question about lipo charging
 
I have a Swallow Advance charger and it only can charger upto 5000mh lipo's according to the manual.
I have a battery that is 5600mh will it be ok to charge it or will I need a new charger?

At 5 amps it will be fine (5000mh) I have the same problem with one of my charger.

No, you don't need a new charger.

Chargers are rated at the max charge rate in Amps or mA they can charge at. Think of it like filling a bucket. The bigger hose you use, the faster it will fill. If you wanted to charge a 100,000mAh battery with it you could, it just takes more time.

Remember to always check the battery specification to see what the maximum recommended charge rate is. if you have a low capacity battery, it is possible to do damage to the battery by charging at too high of a charge rate. Kind of like filling a spoon with a fire hose.

I could be wrong but I don't think this has anything to do with charge rate. I think it has to do with charge TIME. Most chargers will only charge till the battery reaches a full charge, is fully balanced (assuming you were balance charging) OR for only a given amount of time based on maximum mah. In other words...if the battery just won't reach a peak charge or balance, the charger will keep trying for a given amount of time before it simply "times out".
I have to wonder whether a 5600 could reach it's peak rate when the charger is only set up for a max of 5000mah. ??

Thats what I was thinking.

I will use the charger until I can afford a newer one.

Thanks for the help guys

LiPo packs charge to voltage not amps, hit full volts on anything and it's charged, amps barely have anything to do with it reaching a full charge.

it will charge fine, unless your discharging your batteries to far you don't use the entire capacity. safe bet is around 80% discharge.
you will probably find you only put 4,000-4,500 mah back in. worst comes to worst if it hits full capacity just restart the charger.
on a side note, just check as some chargers allow you to adjust the capacity up a bit.
