I put the new battery on charge as per instructions. I am using the charger that came with the blade 400. The lights never changed color even after a couple hours. I put it in the heli and it spools up fine, did this a few times then put back on charger now charge just flashes green red on the cell lights. Any ideas?

I use a 12 volt field battery (hobico i think) with my eflight charger and it will blink if the field batt. isn't nice and charged. so try charging up your field battery then plug up your eflight charger and lipo. I can get about two charges out of my field batt before i have to recharge my field batt. eflight will also have an ac to dc converter for this balencer/charger avalible soon. you might also try going off your car batt. hope this helps.

Does anybody know if it's possible to hook this charger up to
something like a 4 or 5 Amp DC power supply? I ask because
I have a power supply that I used for my smaller batteries and charger
and I know it wouldn't be a big deal to wire it up.
What do you think?

I have the ac adapter from eflight I should check and make sure the out put is correct. My first charge was on a 12v car battery with out the car running and the lights never changed. The second charge was with the ac adapter and the lights are fine at startup but within a few minutes the lights start flashing red-green
I've got one of those bench variable DC power supplies (1-30VDC @ 3amps) at my desk at work and I've charged my Blade 400 battery on it a few times now. No problem.
It has those banana plug ports that unscrew, revealing a hole through the thread to attach a wire. I just clip the alligator clips to the exposed threaded shaft and fire it all up.

If it is the eflight plug that came with the blade cx/cx2 it will not work. I don't think it puts out enough amps.
If you're using the old 1.5 amp AC adaptor used in earlier Blades, it won't work. It has to be the new 3 amp AC adaptor that E-Flite released a week or two ago.
Or you can look at other chargers, or even other types of 12VDC adaptors that have at least 3 amps.

This charger is very picky. Wouldn't work with My CX wall wart either. I did have some temporary success with an old computer power supply.
On the other hand it does charge quickly - even faster than my Rimax AC charger.

The old Wall Wart Eflite AC adapter IS 12V but it's only 1.5 Amp and that's not enough push for
the 1800 mAh battery that comes with the B400
