good point Duster. I would assume that you are using this pack for a electric car and not a reciver pack for your Nitro cars being as it's a 6 cell right?

Like Duster said if it's a RX pack then I would charger it at a lower rate. I charge mine at about .2-.3amps when I have time and about .5-.6amps when I NEED it right now.

With my IB 1500MAH 2/3A packs that I have for my X-Ray m18 I chrage them at 1-1.5amps like I said in my last post. If your charging your batteries at too high of a rate, they will let you know! They are going to get REALLY HOT! It's ok for Nimh's to get warm-really warm when charging/discharging, so don't freak out if they are. But if your like "man that's pretty hot" stop the charge, let them cool for about 2 hours and then charge at a lower rate.
