D4S LTO 6.0 BATTERY
Hi, I'm very pleased with this battery and I'm glad I bought it, it handles the bass very well, I had some other batteries "hc3800 " they were too big and heavy on the other hands the LTO battery is very light and yet plenty of power for any car system and you can mount it anywhere, i love it and in the future I'm sure I will buy more with no regrets but wish the price was a bit lower. Thank you "JP" you're the best.
