since this battery come with E3C, I tried to change to 4mm. However, I got a small spark(short plus and negative) while I clip it off. After connector changed, charging is going well upto 12.4v, but it can not discharge when hook to ESC, ESC no response, receiver no response. Anyone has idea how it might be, or need some procedures to reset?

never cut the power leads together with a metal cutter..short circuit the Lipos and they can burst into flame!! as long as you got lucky and didnt blow it up it should work fine. its not the battery (assuming the pos and neg are correct on the new connector you installed) it should still discharge fine, must be your
ESC. roger

I had charged my Rhino 1050mah 2S 7.4v 20C Lipo for the first time and it worked fine. After discharging, I tried to charge this battery for the second time, all the GREEN LED glows in the charger immedietly I plug the battery to the charger showing that the battery is fully charged. But after charging for over 2 hrs, the voltage in the battery shows only 1.4V. Any idea what is going around?

Hi, Use the 2200ma setting, its only a small overcharge, also I find these packs to be a bit capacity underated anyway.

Can these really handle 20c without puffing?

Newer lipo supposedly can take 2C w/o problem. I use a CellPro4S whose manual say 2C is fine but I still use 1C just in case. Now if I were at the field or in a hurry, I might try 2C.

Would this be a good Lipo to use on a Blade 400? Would it overwhelm or overheat the stock ESC?
|

Overheating ESC is caused by too much current pulled by the motor, not Lipo. Lipo also suffer if motor pulls more current than lipo can put out fast enough. That's the purpose of the C rating...as in 20C, 25C, etc... Multiply C rating by voltage to get max amps that particular lipo can put out, else lipo will be destroyed.

This is WRONG info!!! Multiply the C rating by the capacity (not the voltage). eg, 2150ahr x 20C = 43Amp. (In your example the current would be 222amps! and this is bad)
