Great product

I recently installed two new kinetik batteries in my '99 GMC Yukon to boost the power to my sound system. Kinetik recommended this product to me to monitor the condition of those batteries. It is a cheap solution to make sure that my system is being treated well, and I plan on keeping an eye on my batteries in case I need to buy an actual ctek charger. Incredibly easy to install, water tight cover for the connector and the fuse holder.

SPECIAL NOTE: If you have a side post battery, make sure you buy this one (CTEK M8) because the eyelets are larger for the big 3/8 studs that are used on those batteries.
