I've read several battery pack build threads on this forum, but usually the person already has battery cell in mind when building their pack. In this case, I'd be very interested in hearing from everyone if they were going to build build a sub $500 50-75Ah 12V LiFePO4 battery (with continuous 60A draw) from scratch, how would they do it?
My only bottleneck is with the case since I already have a Hardigg case (13" x 15" x 13") that I'd like to use to put the battery into and then to construct into a PowerBox.
Questions I have are:
1. What battery, voltage, capacity and manufacturer makes the most sense to use for this application? I was thinking 18650 or 38120 since from what I understand they both provide good cycling and are thought to be high on safety performance, but what would you choose?
2. What orientation would you put them in to get a 12V and 50-75Ah battery pack (remembering my dimensional issues)
3. What BMS would you suggest (I'd personally like one with BT so I can monitor and adjust via a smart phone)
4. What charger would you suggest?
5. Is there an off the shelf product available (maybe from China) that would be as reliable, high quality and cost would be similar (say maybe $100 more) vs. building a DIY battery?
Thanks,
