Review on 3.7V 18650 Lithium Battery Cell PCB BMS Protection Board with 5S 50A Balance by David Diaz

The review that talks about increasing the delay for power spikes is correct! These are great little boards but switching between cell numbers with jumpers seems impossible as even a 5 second path on a 4 second board is filled with passives causing a little confusion here to get your 5 batteries to 16 .8 V to balance, which is not very helpful. The capacitor you want to add extra capacitance to (2.2uF worked for my purposes) is third from the left on the passive line, just below the jumper that enables the overvoltage delay feature. If you want to double-check my memory, you can just follow the path leading from the current delay jumper to the confuse chip.
