12VoltInstalls
life passes by too quickly to not live in freedom
I have a couple 140Ah LiFePo batteries on their way. Ya, ya, ya, I know: cheap and maybe not dependable. I only see a few BMS failures- no other complaints and the price is right for ~3kWh of storage.
I bought these:
Now that that’s out of the way let’s not ramble into “should’ve bought …” but stick with selecting replacement BMSs.
Wanting to purchase one or two preemptively, I can’t seem to confirm exactly which to order. Going off of this thread excerpt:
Would I not want the 100A version as the oem rates their bms at 100?
Or was it meant to say buy the 120 and set it for the 100A?

As long as you can wait for shipping from China, the Overkill BMS is just a JBD BMS.
You of course get much better support from the USA, and a real warranty with the Overkill.
You want the "4S LFP 120A UART". This comes with a bluetooth dongle so you can use your phone and actually see what is going on.
Same BMS Overkill sells, Overkill just does testing and support better (and will make custom cables, I prefer the threaded connectors to cables soldered on).
