Which type? I do on my HV's but don't on others. It seems to help a little with voltage but lessens runtime.

Glad to see you came over here nycrc.

But you will need to let people know what the make of your cells are.

Dont know about discharging in general; However, I do believe they need an equalizer.

CT - what's a good equalizer? Been just dumping my pack to 5.6V and then storing 'em. Seem to hold up. Only recently I took to discharging them with an integy individual cell discharger till the bulbs go out.

Thanks.

Seems like everyone agrees, that NiMh shouldn't be deadshort'end. Therefor I would go for an active discharger. Robitronic have a nice one, which auto-stops at 0,9 volt pr. cell. There's LED's for each cell, so you actually can controll that every cell is connected properly and that the cells dump at the same time. Discharge rate is approx. 1 amp. Price seems pretty fair too. You can check it out at www.robitronic.com

I went through the www.team-orion.com and found something on NiMh batteries:

How to treat your 3000 Ni-Mh cells

We've updated the Battery FAQ after having received notice from customers about fast degrading performance on Panasonic 3000 Ni-Mh cells. Now I know that the manufacturer recommends to store them in a charged state, but usage tells a different story.
If you store your packs in a charged state (even partially), performance will degrade very quickly and you will notice a lack of run-time and punch. If you discharge the same packs like you would discharge Ni-Cd cells, race, dump the packs and then put them on an equalizing tray, the performance will be maintained at the original level.


What do you guys think?

I believe that suggestion is meant for the original Panasonic 3000 cells, not the newer SMH or HVs. I'd go with what's good on SMC's website.

This match perfectly with SMC recommendations for Sanyo RC3000HV. www.smc-racing.com -> Products -> Maintenance.

In addition, the guys at our club with Sanyo RC3000HV, has good experience by doing like this.

I still have the Sanyo RC3000H as well as SMHs. Does it apply to them?
