When I set it to self oscillate, the charging batt jumped upwards in voltage instantly and climbed to over 14.60 volts within a couple of minutes.
I found it interesting that I could power the wheel and charge, but as soon as I kicked it into solidstate, the top end (13.5 - 15v) charged rapidly. It doesnt charge that fast when the battery is lower. It seems like a good way to top up the last 10% of the charge cycle. I have still to get a suitable pot to adust the frequencies but amp draw is very similar to its rotational state. The ssg circuit has a bridge to collect to cap and scr.

Ren,
I have seen this happen too, but, my theory is that normal batteries are dead, according to the Radiant charger, so when a normal battery is fully charged, like say it is at 12.7 volts, the radiant charger suddenly bursts it up to 14-15 volts, I think that one should leave it like that to make the battery super charged, with a standing voltage of 13.7v and double the capacity.
Bedini talks about this in the video and states: "A 33 Ah battery may look like a 65 Ah battery".
So, When the voltage of the battery jumps up suddenly to 15 volts, it means that the battery is charged one step and is going to be super charged, if you let it there.
Anyway, only thoughts
