Yeah, pretty much.
Since that one p-group is lower than the rest, it’s going to take a while for the BMS to bleed all the other groups down to match that one during the first full charge you do - And the BMS may get a little warm due to that extra balancing.
After that, it should be business as usual - Keep an eye on it and make sure that one group isn’t acting up, but otherwise let it do its thing.
Thanks for all the help guys! The current plan is to leave it as it is until the weekend when I get my board up and running, watch it charge through the app and keep and eye on voltages while I ride. Most likely will send it to Artem so he can look at it just to be safe. Appreciate all your guys help!
I think the battery building thread is a good place for this…correct me if I’m wrong. OK, I’m ready to attempt my first battery build. For my first build I’m going with the N.E.S.E modules (flat config). I’m torn between a 12s5p and 12s6p, P42A cells. I’m going with the N.E.S.E system because this will be a learning experience for me also I’d be able to correct problems easily. I have not decided on a BMS yet. I like the DieBieMS again I’ll be able to use bolts for the connections in case I’ll need to correct something. I’m looking for some advice…any will help. Thx.
I just clipped the + wire from the BT and soldered the wires to a small rocker switch. That way I can permanently power down the BT without having to remove my enclosure.
I honestly can’t tell if the welds are good or not, everything is too wrapped up. The fact there is a metal tab sticking up is very concerning though and poses a massive risk for a fire (most other exposed parts are grounded, that means almost any contact is a 43V differential)
Did you to the tear test on the welds before you made the pack? It’s a calibration method where you bump the power on the welder until the weld is just strong enough that the nickel rips apart before it separates from the cell, you need to use the exact same conditions in the pack as the test (same nickel, same cells, same settings) or it might end up too weak
