I'm building a 12V, 1,120Ah battery bank using 16 280Ah Keheng cells.
I've been strongly considering the Over Kill BMS. Mostly because I know very little about BMSs, and the Overkill BMS is recommended by Will and others in the forums. At the same time I began leaning toward the Overkill BMS I was also considering building a 24V battery bank. Now, I'm pretty sure a 12 V battery bank will be a more practical way to go since it is for my Airstream trailer, which I'm rebuilding. At this time I anticipate that all of the low voltage lighting, appliances, etc. will be 12V. A DC to DC converter just adds another layer of complexity and something else to go wrong. I intend to keep the shore power 120VAC, 30Amp. The trailer is still gutted. I will be redoing the entire electrical service for both AC and DC.
Just this past weekend someone suggested I consider a Victron BMS. I am considering a Victron Energy Hybrid 3000W inverter and solar controllers, shunt, etc. Nothing, is set in stone. For my solar set up, all I have at this point are 16, 280AH Keheng LiFePO4 cells, and 8, Rich Solar (RS-M100, VOC 22.8V) 100W Mono-crystalline PV panels. I've purposely waited to buy solar controllers, BMS/s, and components while I learn more about them. For me it's still all a bit over whelming, but little by little I'm digesting it. I'd appreciate some feed back on this topic, particularly about BMS brands. I do know that I want temperature sensing capability and Bluetooth capability. The Victron Energy 12/200 claims to be able to monitor and control energy coming from the 12V alternator. In my case this would be from the tow vehicle, since I the Airstream is a trailer. I haven't read enough yet to understand all of this completely. That said I know a lot of you have a very good understanding of all of this. I'd like to hear from you.
