here is another question for the pro's.

with this electrifly charger, will I ever get the batteries full potential? since it only has charge settings of 300, 500, 1000mAh and the battery is 7.4V 640mAh. should I be using a different battery or just buck up and purchase a better charger, like triton jr.? and how long should it take a battery to fully charge with this charger?

Thanks
