I never seen a zapper that hit a cell with hundreds of volts.....little too much on the cells...

In the end, all of our zappers are similar......everyone has their own magic numbers of how much voltage and how many times....

Jim can build a zapper for you.....he is pretty much the only one who does it.

Danny at SMC, nor Rick at Orion will give out their info on their zapper....doubt if brad will either. Zapper stuff is pretty guarded secrets....

Later EddieO

Looks to me like the only way to find anything out is to do your own testing. I would tell you to share your results, but maybe you'll just go into the matching business yourself!

Iwill say this about zappers....Be careful!!!! A good zapper will posess enough energy to kill you.!!!! If you dont know enough about electronics to be truly safe then leave the zapper alone>

Use a 50000uF capacitor.
For voltage, start with 90V, then experiment with 95, 100, 105, or 110V, until there is no IR reduction in the cells.
Current NiMH cells performs best on 100V.

Seems that the "regular guys" are willing to offer some advise but the "big name matchers" will warn you against it because of volatge, etc. I doubt that Rick from Peak will tell me about a zapper.

Anyway, to the regular guys who have offered their advise: Thanks!

To all others: I will eventually get to the bottom of battery zapping.

GC,

Remember, my offer to you is still open... If you want to experiment with a zapper that was used for initial zapping at a "real" battery matcher (Spyked Racing) just let me know and you can grab it from me at the track. I know it'll go to 90 or 100 volts, and it does have a big heavy cap in it, but I'd have to open it up to find the actual capacitance.

The conversion arrived today, it looks great. Looking forward to driving it on Sunday.

David
