Yhen you just buy a 8S extended cable, and put the lid back on. I like his cheapo cell log. It is adequate for counting Ah out. Set it to 90 to be safe.

wouldnt you have to cut the power wires also or unsolder them etc, - or maybe not if not connected to the BMS ? just the balance wires seem connected ?
what are those little red wires that are connected to the Red pos large cable that leads outside to the SB120 ?

Over charge detection voltage 3.8~4.4V (can adjust)
This is the voltage it allows a cell to reach before cutting power off from the charger while it attempts to drag the voltage back down to safe levels. Thats way too high even at its lowest setting, and why all BMS hurt cells... PL8 never lets a cell exceed 3.55 or 3.60V during charge and balance. And it doesent keep switching the charger on/off hour after hour as it tries to do this.
Over charge detection delay time 0.5~2.5S seconds.
This is how long it takes after the voltage reaches the 3.8 (minimum) voltage before it switches off the charger. Over and over for hours.

BM - I remember you saying similar about the BMS I posted in the lithium build thread.
I understand what they mean by overcharge protection, but I don't understand why they need it? If the BMS balances the cells at 3.6v +/-0.025v how can the cell voltage ever get up to 3.8v-4.4v
