for all of you that own multiple helis,

what LiPo Balance Charger are you using?

The reason I ask is...

after getting my TREX 450 together and flying, I need something to charge the 2100mAh 20C 3s LiPo. For the first couple charges I used the E-Flite 2-3 Cell Balancing Charger that comes stock with the CX2 (EFLC3110), this is a great little charger for the Blade series LiPos. However, it took almost 4 hours to charge my TREX battery.

As you can imagine for a heli addict like myself, 7-10 mins of flight for 4 hours of charge time just doesn't cut it!

So, I ended up purchasing the DN Power G2 Balance Charger. The main reason I decided on this charger is because of the features and price. It charges 1-4 cell Li-Ion and Li-Polymer 1-4 cell batteries. It has a programmable charge current from 0.2 - 2.0A, and the best part is the LCD display with voltage meter for EACH CELL! (which is also a great feature to check the charge of your batteries!)

word of caution...
READ THE DIRECTIONS BEFORE USE!

Charging my 2150mAh at 2A only took about an hour, great!

so then, I thought... the higher the charge amps the faster the charge time!

I charged my MegaPower 7.4v 850mAh LiPo [for my CX2] in just under an hour, at 2A... next I plugged up my stock E-Flite 7.4 800mAh (EFLB0990), After more than an hour and a half, the complete charge indication still did not sound, so I looked at the LCD screen and each cell read 4.2V so I unplugged the battery thinking in was fully chargerd. That's when I noticed some swelling in one of the cells.... D'oh

any ideas?
