Awesome trucks. Much nicer than my hack approach. :)

Also, now I see the link in your sig (duh on my part...)

My favorite pic...

that is a pretty great shot!

question: for my 2s2p a123 pack, there's only 1 balance wire coming out to the balance tab. how does only 1 wire balance 4 cells? or is that tiny wire split 4 times and somehow the balancer can see them separately?

[zeropointbug]

Okay, that one wire is a tap to the connection between the 2 cells series connection. Then it uses the main connectors + and 'balance tap'(-), then for cell # 2, it uses 'balance tap'(+) and main battery -.

Understand?

i think so. i at least understand how they're all joined physically. but the charger/balancer only sees 2 cells (series) instead of 4, right? seems to be the case, as the charger will only charge up to 3 cells.

thanks...i'm a balance noob. this is my first set of batts that aren't ni-mh. i guess i don't understand how each of the 2 sets of cells in parallel balance independently of each other... it seems they don't, which doesn't make sense.

hey, as long as they make my truck go fast, what do i care, right?

thanks zpb.
