SamUk Posted January 15, 2016 Share Posted January 15, 2016 Sorry, sure this has been asked many times... Just needed a quick answer..as I'm charging.. My 2s batteries are storage charged..and I need to charge them up..finding conflicting info about charge methods... Should I always balance charge? Or just a normal or fast charge with balance charge after 5 normal charges? Can I charge at 7a? Charger is a overlander rc6 vsp charger Batteries 2 cell, 5000 - 5600 mah. Thanks Sam Quote Link to comment Share on other sites More sharing options...
SamUk Posted January 15, 2016 Author Share Posted January 15, 2016 Also iv set to to charge @ 7a. But its charging at 0.8a? Been at it for 60 mins still not charged...were storage charged origianlly Quote Link to comment Share on other sites More sharing options...
DannyP Posted January 15, 2016 Share Posted January 15, 2016 I always balance charge my LiPo's. Charge the 5000MaH at 5a and the 5600MaH at 5.6a, these are 1c charge rates. You have your charger set to LiPo? What are the cell voltages now? Quote Link to comment Share on other sites More sharing options...
SamUk Posted January 16, 2016 Author Share Posted January 16, 2016 I was not doing a balance charge..so can't get individual cell volts. Noticed it gets to 8.4v, then the charge drops from 5a to 0.3a and just stays there for ages...? Is this normal? Can I remove and use? Am i okay to assume I can charge at 7a as my charger allows it..but its just not good for the battery? Also what is fast charge? Quote Link to comment Share on other sites More sharing options...
DannyP Posted January 16, 2016 Share Posted January 16, 2016 8.4v is fully charged. Don't know why your charger didn't cut out? Yes you could set charger to 7a, that's up to you. I stick to 1c charging. Quote Link to comment Share on other sites More sharing options...
Fontie Posted January 16, 2016 Share Posted January 16, 2016 (edited) Charging at 7a is ok for the occasional charge (I mean occasional) I certainly wouldn't do it regularly, get in the habbit of charging the night before even if its raining the next day and you cant go out they will be fine for a couple of weeks or more, some people will disagree with this all I can say is ive done this, some of my Lipo's are 3 tears old and are fine. As has been said charge yours at 5.6a for the 5000 and 5.6 for the 5600, I also balance charge mine every time this is more habit that a necessity balance charging does take slightly longer depending how out of balance your lipo's are you could normal charge and just do a balance charge every 5 cycles or so. What ever your running your Lipo's in make sure the ESC is set for Lipo and LVC is set, get your self a battery checker I try never to take mine below 20% if that means getting another Lipo to be able to stay out and play so be it they will last for years.

Tug Posted January 16, 2016 Share Posted January 16, 2016 Lipo chargers are CC/CV, this means they charge at "Constant Current" first, then switch to "Constant Voltage" as the cells near full capacity. This is why you're seeing the charge rate change, it's slowing down towards the end. Yes, it's safe to use now. Always balance charge, it's lazy and bad practice not to. 1 Quote Link to comment Share on other sites More sharing options...
