Good morning Jochen from Thailand! Quite a long story to read. To summarize, you found that the charge settings of the Victron isn't matching your LiFePO4 cells and balance. And...

Hello Jochen, Just to be clear, charging to 4.2V is NOT recommend. It will not damage the cells, if you have played some with lifepo4, you know how fast it...

I don't know about your type of cells. 4.3 seems high to me. Lithium polymer has top of 4.2? I'm more LiFePO4 guy (top 3.65) You don't need to start...

I have a "hybrid inverter" so MPPT build in. Edit after the post of @stuartpittaway : The voltage shown on my (Chinese) inverters during usage is roughly one volt lower...

Your controller board can have the relay board.  Each really can disconnect the contactor at a rule. In this situation, when the voltage is above 4.205v (or so)...

At what voltage do you have your balancing set? It seems like they are really close together, and almost reach the balance top of 4.2 at the same time. Even...

The standard 0.8A might be too much for your small pack. It's "easy" to adjust. (@stuartpittaway , please correct me if I'm wrong about this) While you can't really tune...

@axwell Any update if lowering the maximal dumpload temperature helped?

Happy that the workaround did the trick. 20Ah is for this type of BMS "really small" In my experience battery is always too small. For me that stopped after hitting...

It seems like the high Balance capacity is the problem for this (small capacity) setup. With 20Ah, this BMS might not be the best choice. It's functional now, that's most...
