Better than any cap can ever do

June 17, 2012

If you need more power and your headlights dim from those darn caps then get one of these because it will solve your issues. 1200 watts rms and under hands down. DON'T GET A CAP GET THIS. My voltage with cap: 11.3 volts drop. With this: 13.5 on 1150rms in a honda civic with stock alt and batt and 4 gauge. Boom! There it is. NO Brainer and Sonic is a great company that supplies great products, thanks guys!!

Awesome battery! Must recommend

June 11, 2012

I used the battery as a second battery for my stereo system in my car. The battery is very compact and it took place of a much more expensive capacitor. Since it's a dry cell its mounted sideways and it has no problems powering my system without draining my main battery. Only downside is that I had to find hardware to mount things to the terminals.

Serious Charge

August 19, 2012

I use this battery to power two on-board air compressors for air bag suspension on my "pimped-out" caravan. The voltage usually sits at about 12.8~13vdc and never sags below 12vdc whenever my compressors kick in. Did I forget to mention, all my audio is powered off this same little battery. I added a disconnect relay between my main battery and the Shuriken which is controlled by a switch so I can charge the battery when I'm driving or I can let it stand alone for a while and it does a good job. Well worth the money, I will buy more as needed for my other vehicles.

Plenty of power

March 6, 2012

I have this little guy in an icechest radio powering a kenwood kac-8405 amp pushing a pair of Polk db6901 speakers and a 10" sub. It will play at super loud volumes for at least 6 hrs. I haven't seen how much longer it will go. It charges fast and weighs almost nothing. I replaced a 45lb marine battery with this and am much happier when I have to lug around my radio. There are 2 audio shops in town with this battery and they want $145 for it. Sonic Electronix has the best prices I have seen anywhere.

One tough battery

May 17, 2012

I bought two of these BT-20's. I installed only one in the back of my CRX with all 4 gauge wiring for power including 4 gauge from alternator and 2 gauge for ground. I was so surprised how well it worked. It handled the main car power and did its best for the car audio and all vehicle accessories.

So, then I installed 2 in line with a power cap. Amazing difference. I have pushed and punished these tough little batteries to the test and not once have I had any issues. Been installed for about 1 year now. If you are thinking about the BT-20 you will be good to go.

In my opinon there is no need for a power cap, but I seem to overkill. The BT-20 will take care of light dimming issues. Buy one or many and use for any vehicle or car audio power needs you might have. The power ratings are true to specs.

Nice little battery!

July 23, 2013

I've had it since January 2013. Ordered from Sonic. I was building my first music system for my car and had the Pioneer DEH-15UB HU,
Pioneer 6 1/2 speakers in the front doors, Sony Xplot 6 X 9 speakers on the Rear Deck, the Alpine MRP-F300 4 ch amp and two 10" Sony
Xplod subwoofers in a sealed enclosure.

I was going through blogs and reviews about Voltage drop, headlight dimming, and the discharge of the main Battery when the Bass hits.
I was considering purchasing a capacitor because I wanted my music to sound great and was afraid of draining the main battery. My
neighbor had a two amp system with a 6 Farad capacitor in his car, and it looked great. He kept telling me that he usually spent
much time listening to music with the engine off and that he would never had a problem.

Going through the Sonic's webpage, I discovered the vast array of AGM batteries available and after some thinking I decided to try.
I purchased this BT-20 'cause of the price and I knew I did not have a 2000+ watt system. I took it to AutoZone for a pro
installation and they installed the battery in the trunk, in parallel with the main battery without an isolator.
The experience was great. My music sounded with an extra punch and I used to test the music at loud volume for extended periods and
it never discharged.

Today I'm using a 2 amp system. I'm still using the Pioneer DEH-15UB. In the front doors I have 6.5" mid woofers, the same 6 X 9
speakers on the Rear Deck. They are connected to the same Alpine V-Power 4 ch. Plus I'm using one of the 10" subs in a vented
enclosure on the floor behind the driver's seat, and it's connected to the Boss Phantom 1502MW Mono power amp. The two amps connected
to this BT-20 which is now located inside the car, hidden, beyond the area where the passenger rest their feet. I have everything
inside the car, the amplifiers under the seats.

I added the NVX BIR80 80 amp isolator. the experience is even better. The music sounds awesome. It's loud and clear, no distortion.
And I always push it, listening to music for 2 hours or so with the engine off. The 4 ch amp is rated at 300 watts RMS and the mono amp,
350 watt RMS when driving a single 4 ohm sub. That's pretty much the load I'm placing onto the BT-20.

I haven't actually measured the voltage when driving the two amps, but according to what I hear when I listen to music, it's all good. I
cannot say how long it takes to fully recharge it, but I've never had a problem.

I recommend this Shuriken BT-20. It works for me. It has never been fully discharged yet. It's driving my two power amplifiers well. The
music sounds great, with that extra punch. Plus the main battery draining is not a concern anymore, hehehe.

These batteries are fantastic. Don't let the small size fool you. I'm using two of these together with my stock battery to run a 2400w rms amp and voltage is always above 12.5 at full (clear) volume. My only issue is that the posts on them are kinda small and use a small Philips type bolt but it works ok.

I've been an installer for over 15 years and definitely recommend these.

GIT-SUM VOLTAGE with this bad boy.

November 2, 2011

My car was having Voltage drop issues. With a capacitor it improved the sound quality but still had the drop . Decided to go with this battery instead of the Kinetic850 because its cheaper. "Not Cheaper in Quality." WOW the Tremor-X124 sounds like its gonna Blast out of the enclosure. Seriously fixed my Voltage issue although now I have loose paneling in my car because its beatin it down.

I was having severe voltage drop in my car running 900w rms on the stock battery so I decided to replace it with two of these wired in parallel. They work great. Before my voltage was dropping down from 14.4 to 11.9 and now it stays around 13.5 with my system cranked and dips down to 13.1 on bass tests. None the less, these batteries pack a punch for a small package.

July 8, 2011

I installed this battery in my trunk to help power a 3000w amp, pushing 2 550w RMS subs, and it has worked WONDERS. I maintain constant voltage over 13.5v with the help of this battery even during the most hard hitting bass sessions. I did have a little bit of leakage from the negative battery post due to insecure mounting, but once I got it secured and took the stress off the terminals I had no issues. Great product, great value, definitely serves it's purpose and does it well.

Great little battery.

April 8, 2011

I bought this battery for my system to stop the dimming and so far it's working. The battery is rated for a 600 watt amp and my system is a little more but with the two caps with it I think it will be just fine. My sub amp is a Phoenix gold RDS 1200 mono and I have a MA 600 (more like 400 if I'm lucky) running the the 6x9's. I have two Kicker 10CVX102 (L7 but round), I just have one the other one I had to send back and they replaced it, so I cant' wait to put in with the other. I also put a 80 amp iso by Stinger so I won't have to worry about a discharge from the main battery. Here's the thing why pay more when you get the same thing for less. It's a good Battery and I would do two things with it, one a breaker or fuse for the second battery and the iso so you won't worry. Almost the whole system I have bought through Sonic, so you can't go wrong.

January 16, 2014

Decided to add an extra battery for my system instead of using a capacitor and it works perfectly! Placed it in the trunk in an mdf box with zip ties to keep it in place. Also don't forget to use a battery isolator relay so you can avoid draining your main battery when the car is turned off!

For occasional use it doesn't hold it's charge very well. I've got it on a boat and we only get out a couple times a month. The charge falls between uses every time. Once the alternator has charged it back up it's fine, and it only powers the radio so that's okay. I wish it held its charge better though...

Ok, let's start off with Sonic getting this to my door step in under 24, that's crazy fast...THANKS. This has been one of the best upgrades to my system. I had a light dimming issue with my 03 Beetle, it has been eliminated after grounding the big three and installing the Shuriken battery. I can easily tell a noticeable difference in how low and tight my low end has gotten and even hear the mids and highs much clearer. FYI I'm running a 5 channel planet audio amplifier.

Works Great!!!!

July 5, 2011

If your system needs more than a capacitor this is great choice. I had 2 Kicker dual coil 10inch subs and a 15inch with a 1800w Kenwood a 760w Pioneer, and 320w Alpine for my speakers. Then a custom computer with touch screen to run it all powered by 900w inverter. The battery ran all of this very well and never let my amps get depleted and none of the lights dimmed. GREAT PRODUCT

Awesome little battery

December 20, 2013

I put this in as a second battery in my 05 mustang gt I'm currently running two pioneer 1500 watt mono amps (850rms) to two alpine type r12 subwoofers at 1 ohm each 1 sub for each amp, and this battery never misses a single beat I was hesitant because it says it's rated to 600 watt systems, however I assure you it's capable of much more than that also a great size so it's easy to hide and or conceal behind an amp rack. To sum it all up another great product from sonicelectronix

Works better than I expected

November 21, 2012

I bought two of these to run over 2000w RMS of bass. Now let me say: before I got these, I was getting severe volt drop (down to 10.9v) and bad light dimming with hard bass (people thought I was flashing them lol). I was kinda "shocked" lol that although I am running these far above what they are recommended for, I no longer get my lights dimming and voltage does not drop below 12.5 EVER. ZERO dimming lights and I still have the stock alternator. Highly recommended!

Nice little battery

April 11, 2012

Half the size and better specs than my main battery. I got this so I can crank longer at parties. Pair it with an isolator and you are good to go. Very easy to connect and mount. I have been able to run the stereo for DAYS (not continuous) on this battery while testing. I am happy with my purchase.

Second Thoughts

January 20, 2012

I'ts now been 6 months since I installed my pair of these batteries, and one is failing already. I'm not sure if I'd recommend them anymore.

Well Packaged

December 15, 2011

I had a cap-cell from SE that I had to replace with this since it burned out after a week of use. First off, I have enough packaging peanuts to last a lifetime now since the battery was buried in a box about 100 times it's size. Definitely better than finding a lead & acid surprise. The machine screws sent with the battery weren't long enough to accommodate my Monster ring terminals, but 50 at the hardware store fixed that. As with the cap-cell, I have no headlight dimming. Finally, the thing that really matters, SPL. Since the only difference in my system is the loss of the "600 W Cap-Cell", exchanging it for this "20 AH Power Cell". To be honest, despite the cap-cell having to work when the subs were brand new and not broken in, my system had more pop with the cap-cell. Maybe adding a capacitor will help.

Crazy power

July 24, 2012

Purchased this battery to power a stand alone head unit, 2x dj speakers, and a 2000 watt amp. Also used a 1.2 farad cap. This battery lasted my entire show duration, 12 consecutive hours, and still had consistent flow. Used it on and off for a few months to show the audio system. Ended up using it to power a friends jetski, and that is where it is atm. Albeit, prob not the best place for a self contained battery, but its taking the abuse well lol.

Power levels are unmatched. I'm super happy I got this, and would/will get another.

Does what it says.

April 23, 2012

Just wired this in along with a yellow top optima and new tsunami wires. It helps the voltage a little but once its drained its drained (with 1500w rms it drains fast). It does help greatly with my voltage while I am driving though and thats all that matters. For the price it's a steal.

OK little battery

December 8, 2010

I bought this battery to run my 100w RMS amp and it definitely did not do what I thought it would. It only had enough power for my sub to hit the high bass notes. I'd only recommend it if you were running a small amp for your door speakers or something.
