I recently purchased a set of four 2500mah receiver batteries. I am more than happy with them. One bit of fine print on the pack was to not charge over 1 amp rate. Heading this has keep me happy and back to trusting the NIMH packs again. My charger documentation states that you can charge them at 3 amps and I tried it with a previous couple backs and I killed both of them. Same for a TX battery I bought. I overcharged the first and it almost cost me a plane. Turned the TX on and it showed 11.2V and three minutes into the flight the low voltage alarm went off and when we landed (I was still on the buddy box then), the TX was showing 8.3V.

As for taking to long to charge, an over night charge on the wall wart that came with my radio is all I do for charging most of the time. That and top off the RX at 1.0amp with my field charger after three or four flights. It usually is back up to full after 10 to15 minutes on the field charger.

The RX batteries cost me $10 each on Ebay and the TX batteries were also very low priced. I forget the seller now, but if I need more, that is where I'll buy them.
