XS Power 551 battery adapter was a perfect fit for my XS Power D3400

Am currently using this battery adapter for my XS Power D3400 battery under my hood, easy install and easy to be used all around. XS Power all day, everyday!

EXCELLENT!!

Used it with a D3400 and the fit is immaculate!! My only gripe is that the 3/8 holes were not deep enough for my short Stinger side post adapters but for the flexibility I acheived, I don't care.

Excellent Fit.

Product does exactly as advertised. Looks very nice, and was easy to install. Compatible any new XS Power battery. This was used on a XS S3400 Battery.

Not as advertised

I bought this thinking it would work for my new system install. It did not fit and I did not send it back cuz shipping was more than it was worth.

XS Power 551

Works well, as a started and auxiliary battery. Definitely a good decision.

Perfect for what I needed

I bought a pair of these to use on my full throttle g34. They fit great and got the job done. I did have to drill out the mounting holes because the bolt on my full throttle battery were larger but thats very trivial.
