Discharing my NIMH packs has always yeilded me better results.
I believe RX packs , you charge @ 1.0amp
TX packs @ .5 (I just use 8 rechargable energizers...there 2500mah nimh
Discharge you want at about 1.0amp so all you need is one automotive bulb and whatever connector you use. Futaba, etc. and wire it up and discharge em. Only problem is your supposed to cut them out before they start to dim. So pay close attention. Never let the light dim.
I think nicd you get them to a low glow?? Not sure I dont have nicd.
Also lots of chargers have up to about low level dischargers which is good enough for about anything small. But yeah never go over 1.0amp discharges on RX/TX packs.
Then you let cool and charge. The main thing is too keep these things cool, dont let them sit too long. When you use it up and they are warm....let them cool then recharge.
If your going to store them , store them at half charge.
Then discharge and re-charge before use. That should keep things nice , keep them running longer and get more uses out of them.
There is also a guide on trinity for nimh batteries and elsewhere on the web.
I really dont like all the literature that always says these batteries dont need anything. They do and they seem to die quickly if you dont treat them just right, store them just right and charge them just right.
