I've nearly finished upgrading the controller and battery on my Giant Trance.
I've taken the unusual step (I think it's unusual anyway !) of reducing the shunt cross section to increase the resistance and reduce the max current down from 25 amps to about 18.
I checked the plan with Dave and he's confirmed the idea.
I used a small grinding wheel in my Dremel to grind a shallow curve in the top of the shunt to reduce it's cross section to about two thirds. I've wired a GT power meter in, so I'll be able to see what the max current under load is. (and adjust again if necessary).
I'm very pleased with build quality of the S12S, nice soldering, and neat cable entries and seals with rubber gaskets rather than great gobs of silicon. Very quick delivery as well, just 7 days.
