2hrs first charge?

[vwdave]

Have a 2s lipo from SPCRacing.com that has been on balance charge for 2hrs. This is the first time charging it, but this can't be right. Bad pack?

Balance charging can take a real long time sometimes, I wouldnt worry. Your charger have a readout?

yeh i did a balance charge on some of my 2200 3s packs and was taking about 2hrs or so. it only trickle charges the last part at like 0.1A which is just balancing each cell. its obviously out of balance tho if its taking 2hrs (like mine were)

Yea it has a readout. Was boucning between .1 and .0. Charger times out at 2hrs. Going to try a storage charge and charge from there

just start a balance charge again. it shouldnt take much longer. my cells were out (4.01, 4.01,3.91 for eg.) and yeh it took a while. let it complete a balance charge. and next time you charge do it again. but after that you only need to balance every 3-4 charges (or every charge if you have the time)

I balance charge my packs EVERY time i charge them, its not healthy for ther cells if you dont balance charge them.

4 hrs now and it still will not balance charge. Time to contact SPC.

cycle the battery, when its charged (even if its not completely balanced) let it cool off, set your charger to storage mode, once its down to storage, take it off, let it sit for an hour or so, and recharge, cycling will help the life of a battery, i do this about 4 times to all my race batteries, before they are pun in my Rc's

 

[vwdave]

By cycling u mean charge it to peak the down to storage?

yes, do that a few times, charge it as far as it will go and run it, when you hit lvc, put it on the charger and see if it balances
