Better than most others
Great quality battery I have 3 of these and they work without flaws. Great Buy.
So far so good ! Currently I've purchased Four (4) of the 12v 300ah batteries for my home backup/solar project, and I'm looking to add 4 more. The quality looks to be good, and the built-in Digital BMS & Info Screen are very handy. The only real complaint I have is that I wish the screens 'orientation' could change so I could mount these in different ways to shorten wire lengths, while still seeing the screen in the proper orientation.
Great battery, nice lcd screen information
Love this battery, works as advertised.
