I just got a 6 volt Nimh battery . And charger . I am very happy with the long charge, speed, and extra power. The charger cost 35.00 - Batt. 32.
I will never go back to 4.8 volts.
Could someone tell me what this battery needs as far as do's and dont's, compared to NiCd.

OK <div>I found out this battery likes to sit in storage with a full charge.</div><div>and it does not slowly wear down , it will die ,and I will crash.</div><div>Is an over charge bad , even if it is a trickle ?</div><div>

You just look after them like nicads, and you will never have any problems with them. They are like nicads except for the memory thing so some say. They have a better voltage/power curve than nicads and seem to last a lot longer for the same size pack. Enjoy.

Also, you need to pay close attention to not overcharging them. Either us a charger that will shut off when they are charged, or closely monitor the time you have them on charge.

Ni-mh' s do not maintain charge levels very well. They will lose approximately 5% of their charge per day, down to a certain level. So it's best to charge them up the night before you are ready to fly. This does not apply to the new newer Enerloop Ni-mhs that will maintain their charge level for very long times.

I just charge them and leave them on trickle. The only thing to really know about them is they don't like to be fast charged, fast field charging doesn't hurt but they tend to not last as long if you use a fast charger a lot. Fast charging heats them and they don't like that. I charge at home but still fast charge them at the field if needed. When they poop out I just buy another pack. I have been making up my own packs using the Enellops, like Ken mentioned, there claim to fame is they don't discharg themselves when just sitting in my shop doing nothing.

Gray Beard,
 The other claim to fame for Enerloops is that they are very tolerant to being quick charged. If I remember correctly they can be charged at up to 2C rates.

Just to keep things safe, I charge my NiMh packs at 1C and no more. Obviously, that will take an hour for a full charge, which, as far as I am concerned, is a good thing. My packs last pretty long. In fact, in one of my threads about restoring a plane that has been sitting around a while, there was some focus on the battery packs.

I looked at my packs on the Venus II last night. Both were fine. A little low, but they held a charge. I put them on the charger at 1C and they took it just fine. I want to run them through the cycler just to see what their capacity is, but will do that tonite because it takes longer to do that. I use my Accucycle for that, but charge it at 125 mah per hour with that charger, which will take most of the night.

The purpose was not to "cycle" the packs, but to check the charge level aftar a so-called "full charge" at 1C.

I also bought a pair of LiFe packs. The charger, a Triton EQ is due to arrive today.. even UPS will deliver in this crappy weather. Aaaanyway, I'll run these packs through the charger then see how I may use them as a replacement for my NiMh packs. They are 1800 mah by the way, and 6.6 volts nominal (3.3 per cell).
