In one of the last videos ( • SEPLOS SMART BMS: as g... ), we have fully top balanced the Seplos MASON 6.9 battery with the help of an active balancer.
Now, after a full charge again, we want to have a look how the BMS balances the cells. What can I say?! Even after 2 hours sitting on 56V, the voltage difference has only decreased by a tiny tiny bit. The balancing of this BMS really sucks 🤷♂️ It seems to have far less than 150mA of balance current and has pretty much no effect on these cells. I have charged the pack to 58V, so really in the top steep area of the charging curve, and even here, the Seplos BMS cannot balance the cells effectively.
Even the QUCC BMS in the good old days had a better balance outcome.
I had very little hope in this BMS from the beginning but the reality is even... well, see for yourself!
I don't know what to say about this BMS but it definitely cannot live up to its hype.
