Check with the manufacturer of your cell, but I'm going to say a max of 1.5C (if your pack capacity is 1100 lets say, your C rating is 1.1, so your max charge rate would be 1.65A. This should charge your pack in 40 minutes.) If your cells heat up quite a bit, it usually means they can't handle that level, so you have two options:

- put a fan on them to help keep them cool.
- lower the charge rate

I typically let my cells hit around 120° F, however, I've got one pack with a bad cell, so I have to cool it down using a fan. (FYI - the heat comes from the cells internal resistance while trying to take on power.)


P.s. To calculate how long it should take to charge a battery at a given rate, do the following:

[ Battery Capacity / Charge Rate ] X 60 min = Time to Charge
