I’d like to restart this discussion.
Bottom line: there’s gotta be a way to add more batteries in parallel hot swap style to push more amps on the fly.
I’ve done a ton of research and reading on this forum and others, but I haven’t been able to come to a conclusion, so I’d like to restart the discussion here. To be upfront, I know it’s dumb, just build a bigger P pack you say, but I can’t right now and I’d like to put all my extra less capable cells to use if I can.
I remember (I think it was) stooge talking about lipos and liions in parallel, and how the lipos lower resistance allows them to take all the extra amps that the liions can’t safely push, just naturally.
I want to be able to parallel some old cells to push 20-30A more on my 10S setup.
I started to consider safe ways to limit the current drawn from the additional parallel cells, and looked into current limiting resistors. For the right kind, they are either way too bulky, can’t handle enough wattage, or are prohibitively expensive… Like new 12S8P expensive, defeating the purpose… Being cheap!
My thoughts- can the wire itself limit the current? 16 guage to the additional lower amp capable pack, and 10 guage from the main pack that pushes 80A? The idea is that if the current can’t pull from the higher guage wire due to increased resistance under load (gotta get the resistance just right), it will just pull the remaining current from the main pack, just as intended.
Does anyone else have any ideas how to safely limit current over one set of wires to supplement a higher current pack besides higher guage wires or current limiting resistors?
