help please,
when charging my lipo's for the first time, the charging battery went flat, my charger is a schulze 6-636 and it displayed car battery voltage low ( words to that effect), so i disconnected it, the lipo's charged to 20.9v, should peek at 21volts, but was only 35 mins into a approx 1-1.30 hour charge, its the fist time using the lipo's and i dont want to damage them, my question is can i continue charging them, or just charge the other pack to the same point, and use them, and recharge them afer that?

thanks

andy

I have the schulze charger they are very good

its not a problem just plug the li-po back into the charger and away you go it will detect the state of the li-po and reduce the current accordingly

I normaly only part charge my li-po batterys then let them settle to balance the cells for about 15 min then finish them off yo dont have to do the full charge all in one hit

As Steph says, these cells don't really care about partial charging. However, if you are considering charging or using two packs in series definitely balance them by fully charging them independently fairly frequently or some unwanted excitement might occur.

Also, when you charge LiPos, you aren't terminating the charge with a peak detector. You are tapering the current with a constant voltage. This is not a subtle distinction!
