Lipo Balance
 
My red balance wire broke on my lipo and i was wondering if it was ok to not balance it and just charge it:deathstar

What brand lipo? If this is something like an Orion with high quality cells, you're prob ok. If its something cheaper, you may be Ok for one or two charges, but you need to get the broken wire fixed or better, replaced.

Its a Venom And yes i know there crap:flaming:

Do you have a DVM? You can measure cell voltages and see how bad they are getting - and let that be your guide for how long you can continue to use it.

If you repair the wire and re-connect/splice the red wire, that will throw off the balance readings. Only way to fix this is to open up the lipo and replace the red wire with one of equal guage and length and re-shrink the cells. I'm not sure its worth that much time and trouble.

isn't the red wire typically connected to the positive side of the final battery in the series, meaning the positive connector on the battery is attached to the same point?

if that were true, perhaps you could re-attach the red wire to the positive lead on the pack?

ahhh not a good idea:weird:

Since balancing is dealing with such a small voltage amount (5mv = .005v), the balance wires have to have the same resistance otherwise balancing is not going to work right. Using the main power lead directly as pac positive like that isn't going to work.

Charge it and run it and repeat til it puffs a cell or gives up in some other way. Then buy a better quality lipo.
