Celectra 1S 3.7 Variable Rate DC Li-Po Charger on 120 &150mah batteries?

pcnewman · 07:58 AM

I just received the charger listed below and a 120v x 6v 1500 mah power source from ebay. The instructions only refer to charging a 500mah battery. It says to charge the 500hah at .7 but I plan to use it on 120 and 150mah batterys. It's variable in tenths from .1 thru .7ah. What setting would I use for these batteries? Eventually I hope to get a Parkzone Masquito which comes with a 250mah what would I use for that? Any help would be greatly apreciated.

I spoke with support at Horizon Hobbies. They said 120 and 150mah should be charged at .3 amps and the 250 should be charged anywhere between .3 and .7 amps. Sound right to you folks?

The safe suggestion, to reduce the risk of damaging the batteries, is to charge at 1C. A 1C charge rate is basically the capacity of the battery. A 100mAh (0.1Ah) battery is charged at 0.1A for 1C. A 300mAh (0.3Ah) battery is charged at 0.3A for 1C, etc.

If you want to play it extra-safe, charge the 120 and 150mAh batteries at 0.1A, and the 250mAh batteries at 0.2A. That will be under 1C. Or go to 0.2A for the 120 & 150mAh batteries, 0.3A on the 250mAh batteries, to go over 1C.

Your power source description kind of puzzles me. Do you mean 120V AC to 6V DC, and 1500mA (1.5A)? That's what my 1-port Celectra came with.

That makes sense. Thanks for the info and yes I meant, 120V AC to 6V DC, and 1500mA (1.5A)?
I've charged two of my 120's at .3 and it took the same 25-30 minutes as the charger that came with my Champ. It must be charging at .3 also? The batteries have never even gotten warm to the touch when charging but if a lower rate will add life I'm all for it.
Thanks again.
