The rotor is from an old 5" floppy drive and the magnets are neo's . I have a vid of the setup here for those that are interested. YouTube - SSG Video 2

I have many q's but at the moment I would like to know if it is better to attain the fastest rpm, or the most rpm for the lowest draw off the primary batts.

Cheers,

P.S sorry about the massive photo.

You can convert the photo to a smaller one with "Faststone Image Viewer" it is free and works great! ( simple right click on photo choose batch convert ) then lower the scale of the jpg quality.

The goal can be what you want it to be But the best is to look for conditioned batteries. Batteries that charge up fast and give their charge slowly.

Here is what I do for a conditioning process.


I will leave the battery on the SSG for days till it reaches the top voltage. Then I will put a load with its c20 rating ( fancy term for 20% of its rating ) till I have went down to 12.5V for standard batteries, 5.5 for my golf cart batteries. Then I repeat, the process of charging them normally gets faster with time. Note this takes months to get up to a "supercharged" battery and you will loose if you use a conventional charge, or.... if you let the battery just sit.

Goal number 1 for me is to get a conditioned battery, then after that you can optimize the energizer. Until the battery is conditioned, it will jump all over the place in voltage and you will be scratching your head thinking.... what did I do wrong on my energizer. This can be normal, the batteries often drop in voltage, then rise then drop until they stabilize with the new method of charging.

Note on your neos to keep it about 1/2 inch away from the magnets, you will find that it will take less amps this way ( at least I did ).

Many methods out there for tunning the SSG, mine is to watch the target batteries voltage, the question is, what I change, does it make it rise faster?

I have found that leaving the batteries on the SSG for days has really helped my good batteries. The bad ones... well ehhh i don't spend the time on them anymore. Too many batteries out there for me to fight the ones that take months to bring back.
