5 out of 5 stars review
I wish I would have known my 12V 200Ah 100Ah BMS batteries required this charger in order to bring them back from the dead. As soon as my batteries died, I had no way to recharge them. So I did the research and ordered this bad boy immediately! 2 day shipping made my life just that much easier and now I have power once again!! I keep it plugged into the charger which is attached to my 5000W generator and I only run it when I need a little extra power in my camper (which I live in - completely off grid - full time) like when I want to enjoy some AC. Anyway, my only recommendation would be to sell a package of the batteries with the required charger so newbies like me see the option and chose it from the beginning. I'd also like to see a package sold with the controller as well. The charger has been a lifesaver for me. I was panicking and now I'm sleeping like a baby.
