Nimh RX pack charging question

[spamless]

Just moved upto an 6V Orion 1100 mah receiver pack and am wondering if
it is possible to charge this pack using my Futaba slow charger. This is
the dual model which gives either 4.8v at 70 mah or 9.6V at 70 mah.

Would it be possible to use the 4.8v output to slow charge this new pack
or is a new charger in order?

A new charger is in order, one that will charge Nimh.

You will never achieve a full charge using a 4.8 volt charger. You need one
capable of 6 volt charging. And the other poster is not totally correct.
You do not need a designated NiMH charger when you are only trickle
charging. A distinction in charging NiCds and NiMHs really only becomes
significant at high rate charging where the cutoff is more critical for NiMH
than NiCd. NiMH is more subject to overcharging damage and has a smaller
voltage drop off as the charge peaks. That is why peak chargers have
special NiMH cycles.

When you're charging at something like 70 mah rates, the likelyhood of
overcharging is very remote.

My point is, neither one of the chargers he has will work correctly, so he
might as well get the correct charger and do it right. Why spend money on
something that will take hours and hours to charge that battery.....and if
left on by mistake and heats the batteries up will ruin them. The chance
might be remote, but why take the chance at all. I'd rather be up and
running in a hour or less then the next day.

I agree with everything you say. I just wanted to be sure the original
poster understood all his options. Like you, I would opt for a good quality
peak charger.
