Cycling Question

Question for cycling High Voltage 3000s

On your site you recommend a .07 cutoff, I presume this is per cell and the total pack cutoff would be .42.
Second when you cycle your packs what are the steps that you follow?

Example: charge, rest 5, discharge for 1, rest for 1, repeak, rest 1 then fully discharge.


Thanks

Crash,

A .07 per cell cutoff (or .42 for the pack) would be WAY too much for any cell, even nicads.

For Sanyo 3000HV, most of the fast guys around here use .07 for the pack as the peak threshold, and for Panasonic SMH we use .02 or .03 for the pack.

I'm not speaking for SMC, but I'm pretty sure they'd tell you the same thing.

Default Cycling routine!

I have been cycling my pack using the formatting routine done by the orbit microlader charger with great success.

First, I cycle my packs when I am unable to race for two weeks or more. I try to cycle every two weeks hence.

Secondly, the system I use is as follows:

300ma for charging with .04 threshold
5 amp discharge (lower up to 300 ma if your discharger will allow it)

I do one cycle on my turbo 30. The reason I have adopted this routine is because it does not stress my packs to much at the same time conditioning the cells. I am banking on the fact that nimh cells do not have memory and thus the low charge and discharge rate will not affect the performance of my cells.

I still charge at 5-6 amps .04v for my races.

thus far, my orion hv packs have kept their capacity, IR and voltage.

By the way, one cycle takes about 8 hours. I just leave the turbo to do it while I'm sleeping or when I go to work in the morning.

Your thoughts on this routine requested.

Thanks!

Yes Trips is right we use .07 per pack or 12mv per cell.
