Hi all,
A follow up after I've been using this modification for a while. How do you guys make sure that the pair of cells stay balanced? I think mine is getting out of balance because when I charge it the charger breaks off the charge before completion, after hitting 8.4V for a while, with a "Disconnection" message. I assume that's one of the cells topping out and the protection circuitry being triggered and going open circuit. Also once the pack's in service the voltage drops really rapidly to 7.4V or 7.5V, then very much slower from there.
So for all you more experienced guys using this modification, how do you charge, and do you fit and use a balance lead?
Thanks, Tony S
