Good catch on the solder ball! I'll be more careful of that next time. That might explain the bad PCB but I doubt that would cause the issue with not charging on Makita Chargers. I'll be extra careful with this next one and see if it charges on OEM. Thanks for the recommendation I just ordered...

I received the replacement board and plan on soldering it in soon. I do have a question about the bars though. The through holes for the bus bars are significantly wider than the bars themselves. Are you going out of your way to fill all the gaps or just enough solder to connect the side of the...

I built 4 of them and think I did a decent job of it. 3 out of 4 charge on aftermarket chargers only. 1 doesnt charge on anything but works fine. Waiting on the seller to send me a new BMS to rework the 1.

I haven't run any of them down far but I just confirmed #1 out of 4 charges. It didnt work a few days ago. I messaged the seller but they have been slow to respond. All they said was to check pack voltage and send a picture of the board. I didnt think i spent too much time with the soldering...

My pack voltage is around 20v. I bought an xtar 8 bank charger and charged all 40 cells before installing them. I haven't run a pack down yet. I ran one of them down just one light bar and decided to give charging a try. Thats when I found out none of them would charge.

Hey thanks for the recommendation. aftermarket? 4 pack battery build kit you linked and built it with molicel p42As. Everything went together seamlessly. The first 2 i didnt realize the thermistor wasnt touching the battery so I desoldered the board and bent down the thermistor so it would touch...
