What's the circuit breaker DC rated at, out of curiosity?
No idea. All I know is that it's rated to 240V AC, 50A trip, and up to 10,000A fault. The bit of wire inside it is 10ga. 72V should be no problem.
Anyway! Modding done! Moar pics!
What I started with. I ended up covering the entire table with boxes, tools, electronics, and batteries, LOL.
Stock controller innards (USB cable for throttle).
Pic of the schottkys. I could find no spec sheets, but I'm very sure they are rated for 20A and 100V based on the naming schemes of identical diodes.
Useless pic of board with caps, FETs, and diodes removed.
4110 FETS, 100V 470ÂµF caps, and stock diodes. Modding done!
Battery block. Wiring was tricky (had to keep the 5Ah and 4.5Ah batts electrically separate, both for protection and charging), but it works excellently.
Controller connector. Puts the batteries in series and adds a 48V tap for the board logic.
And a bigger pic of the bike itself.
Speed tests due within the week.
EDIT: Vid is up.
Predicted speed based on performance in 26" wheel at 48V is just above 30mph.
