In normal use, there is no throughput in the leads connecting parallel cells, except for the end cells in series.Spongeworthy said:Why is it more important for the ends of the pack to have more conductive mass than say in between each parallel group? Doesn't the same amount of current run through both? I'm just a bit confused since I see some packs that don't do this at all and just solder leads directly onto the + and - ends of the pack, and other packs with thick copper bus bars at the end.DrkAngel said:Ideally with a reasonably heavy (large gauge) "rail" to provide good equal discharge from each series of cells.
The large end rails allow a fairly equal draw from each series >> cell, meaning that there is no voltage differential between parallel cells, thus, no voltage-amperage throughput on the parallels!
Parallels are to confirm voltage equalization (balance), buffer minute capacity variances and insure against a single series destruction in the event of a single cell failure. - Will 90% buffer voltage deviance in 10 parallel battery.
Spongeworthy said:Not sure if I'm misunderstanding your post, but why's it carrying 10 A from one series group to the next? Like I said earlier, doesn't the whole 80A run through each series connection?
