HI Frank,
I have one of these and have no manual for it. Would you have a copy you would email?

Tom, I think I have something - let me look and I'll email off-line.
oops, I thought this was one of my ads. I have one to sell.
Sorry. I confuse too easily!
Let's team up Tom, double the pleasure, double the fun!

What is the charge algorithm for this charger? Im interested.

Is the input voltage just 120 for this size charger?
IIRC it's CC, CV. It's set up so it needs a 12V input (presumably controlled by a BMS) but I fed it straight 12V via the second SB50. I cannot recall what happened end of charge but I can look in the manual and report back. I had the Thunderskys on a commuter bike that I turned into a drag racer in 2014 so it's been sitting awhile.

Yes it's fed from 120VAC.
There are two small adjusting screws: one to control CV voltage and the other to control shut-off current. I liked this charger as it is isolated but once I moved to the higher voltage packs I couldn't use it.
