I built a tandem using a Crystalyte 5303 front hub and 4840 controller running 54V. It has a 3 power level switch, a Clite cruise control and a thumb throttle. Even in low power, it's more than I want and the bike wants to go faster than 20 to 28mph range we like. In high power, it delivers the 40a plus a bit (2400w w full charge). Nice on a big hill, but I think 25 to 30 amps max. would be more suitable.
I know adding solder to the controller's current shunts will fool the controller into providing more amp than rated. How can I fool the controller in to providing less current than rated? It has 2 shunts, cutting one would be too drastic.
Any ideas. Any side effect that I should know.
BTW, I have 2 more 5303/4840 NOS combos, I plan to list for sale in this forum. Wonderful for tandems or if you need a 40mph single.
