5000 can charge at 5 Amps.

basically the mah/1000 is the charging current.

Sorry to hijack the thread but how many of you actually charge at 2C rate (granted the charger/battery allows)?

Never. Always 1C or less per the mfg instructions.

I look at it like this. Do you want it to rain so the ground gets nice and evenly soaked and your lawn turns green, or do you want torrential downpours and flash floods ripping your house and lawn away.

Besides, charging at a higher rate doesn't really decrease charge time that much. It does not increase potential and can cause damage to the battery which in turn makes for a very dangerous situation.

depends on who makes the pack... most of the top brands say you can charge at 2C which would be 10amps... i charge all my SMC packs at 10amps even my 4500 and it works fine...

some if not most packs claim you can charge at 2c but it will shorten the life of the pack.
I charge all my batteries at 6 amps which is just above 1c.

These batteries do not use a Delta peak but must be charged with a charger that can do lipo and use a CC/CV charge profile.
CC (constant current) / CV (constant voltage)
What this means is that the charger in CC will charge the battery till it gets to the max voltage (4.2v per cell).
At this point it will switch over to CV and hold the voltage at 4.2v per cell and gradually as it fills the battery up, the current will reduce till the pack is full.
