Disadvantages of low capacity cell?
#11
I thought that would be an advantage of having many batteries in parallel. But in practice, I cannot take any battery offline for long while they are being charged(discharged), because when I reconnect them later, it will have the lowest(highest) voltage and thus most of the current will flow into(out of) it, tripping the BMS.
Perhaps it will work better once I have much more battery capacity.

In the meantime, I do maintenance around 1~4pm when all batteries are full. Then they also have similar voltages as my replacement cells, so I can solder them in right away without spending time matching voltages.
