However, I think stuball56 has a point.

Grampi, some of the basic questions you have been asking has me concerned that you may need to study up a little, before making your own charger leads and such.

1C is a term that anyone and everyone should fully understand before attempting to modify a LiPo charger, or its leads.

1C is the recommended charge rate for the E-Flite batteries that come with the 120SR. Charging a 500mAh batt at .5 amps equals a 1C charge rate. Charging that same batt at 1 amp would be 2C. Understand? 1C is the exact same rate that you are saying is too slow for you.

I highly recommend that you take a crash course in charging LiPo batts before you get too far into your modifications. For your own safety, if nothing else.

I noticed the input specs on your charger (11v to 15v DC). Does it have an AC input also, or will you just be charging from a 12v DC source? May be a point to consider?

Also wondering if the green connector terminals on the back of the charger are labeled, and if so, what are they labeled?

There's a couple reasons I'd rather use my DN charger than the one supplied with the 120 RTF. I can set the charge rate anywhere from .2 amps to 2 amps on the DN. The RTF charger can only supply .7 amps to one battery, which means charging 4 batteries simaltaniously it will only charge at .175 amps...this would make for some long charge times. I can set my DN to charge 4 batteries at .5 amps each, plus it conditions the batteries while it charges them. I actually used to know all this stuff, but I've been away from it for a while so I'm trying to clear out the cobbwebbs.

I do all my charging with the DN using an AC adapter. Not sure what the green connector is for, I've never used it and I don't have the unit with me to look at it.
