@Haugen -- did you manage to get the connector and its protocol? I have a similar variant (0.6A balancer/100amp bms). My unit also has both the CAN/RS485/GPS ports but not sure where to get the connector box or how to get its protocol. Any help is great, thanks.

Here's a test during discharge (10amp controlled discharge). My pack is 2p16s (total 200ah) built from 32 100ah cells. All cells are compressed using 4 threaded rods for each group (can see below). On the screw itself : On the busbar : Here's what the BMS reports (I'm using 0.6amp active...

I'm reading higher voltage at the busbar when there's active power flowing (i.e 5A charging). 3.25v at the stainless screw/bolt while it's 3.38v (or higher) when touching the copper busbar. Usually its higher in the busbar than the other way around. No idea if the busbars are tinned, so higher...

I'm finally in the process of building my first LifePo4 pack and I bumped into a really weird behavior that I can't quite explain. If I compare voltages between screw terminals, I get reading A. If I compare voltages between busbars (connected to the same screw terminal), I get a different...

Hi everyone! Nameste from India! I've been trying to buy those 280AH lifepo4 prismatic cells from the deals in the other threads (via Alibaba) but unfortunately, none of the sellers are able to ship to my country which has been a very frustrating experience so far. (if anyone of y'all are from...
