Welcome to RC-Monster! Another one who has caught the electric bug!

My LHS owner says he dose not charge any Li-po’s over 1 amp to be on the safe side.
When charging Lipos, the easiest way to determine the charge rate is to get the capacity, divide by 1000, then multiply by the manufacturer's recommended charge rating (the 'C' part - this is usually 1C, so stick with that to be on the safe side).

Example 1
Battery 8000mAh, max charge 1C
8000/1000 = 8
8 * 1 = 8A

Example 2
Battery 2500mAh, max charge 3C
2500/1000 = 2.5
2.5 * 3 = 7.5A

Nickel based batteries can be charged at about 2-3 C safely, but watch the temperatures the first few times, don't let them get too hot.

I don't have experience with that particular charger, but they all work using the same principles as above. Just make sure the charge settings are correct, and you should have no problems.


In the beginning the Universe was created.
This has made a lot of people very angry and has been widely regarded as a bad move.
