Rx/Tx/ EZ-Start Batt. Charging Questions
I know this might/should go in the 'Radio" forum but since it's about more than just radio batts, and there is a lot more activity over here, I'm hoping this is OK!!
I have a Duratrax Intellipulse Digital Peak Charger that I use to charge my 6V 2700mah NiMH Rx pack, 7.2V NiCad stick packs (for EZ Start), and for sets of 8 AA NiMH batts (for the Tx, charged all together in an 8-cell holder).
What charging AMPERAGES are best for these examples?? The paperwork for my Rx pack was kinda vague & aimed mostly at sub-C packs, the Duratrax manual is completely devoid of suggestions.
I don't want to/need to push these batts to thier limits, like the electric car/sub-C guys need to do, nor am I ever usually in a hurry to get them charged quickly.
I just want good performance/"run time" AND I don't wanna damage them. But I've heard that sometimes using too LOW of an amperage is as bad as using too MUCH!!
Any help would be appreciated!!

RE: Rx/Tx/ EZ-Start Batt. Charging Questions
Basic rules of tumb(s?) thats I've come across:
NiCad's can acept much higher charge/recharge rates than NiMh
NiMh are much more prone to damage from overcharge than NiCads.
CHARGE THEM AT 1/10 RATED AMPs.. So a 2000mA would charge best at .2 A.
1A= 1000 mA.
Heat is your battery's worst enemy.. If your battery is HOT.. You overcharge/discharged it... Oops!!
Hope that helps
