Hi,
new here but looked around... at any rate I just built my first battery with a vruzend kit
36v 10s6p with new 30q cells Ill break down my process but when I finished full assembly the pack was reading 34v... not biggie..so i charged the pack up and it stopped at 40v not a close to 41.5-42 like my other pre-fabbed batteries
anyways heres everything i did to this point and any thoughts are greatly appreciated..
new 30q cells arrived...i unpacked all and tested each to make sure all had charge and same voltage...all reading 3.7
i start building parallel groups of 6.. add the top caps and compress them all down onto the cells and then re-verify each cell has contact in the caps and showing voltage...YES
I start assembling the parallel groups in series (rectangle shape) ... now before adding the bus bars for parellel and series connections I DIDNT do one last voltage test of each cell as the whole pack was assembled...i assumed all was still good after parallelling them
I add all bars for series and parallel connections... add the BMS and balance wires and all that final wiring stuff... END
so what could it be? all cells cheacked out on the way in... and at the end we are where we are.
thanks
