October 14, 20196 yr Author I am going to look in the controller this evening! But can anyone recommend a controller to give more power. I am not worried about killing the battery
October 14, 20196 yr I'm going to through another possible option put there.....a booster battery Beg, build, borrow or buy a 2 or 3s battery Cut the main power wire to the controller. Add the booster in series Comes with risks of damaging controller and not always that cheap (if you have a suitable charger , soldering iron and basic skills as well as a multimeter then you are halfway there) I've done this quite a lot in the past and currently occasionally do so on a 36v xf07 front conversion. I splice in a xt60 connector and then make a matching xt60 blank. Leave blank in for 36v or remove and and booster battery for more speed and torque)
October 14, 20196 yr Author Take the end-plate off (4 screws) and have a look inside. There's no need to open the whole thing until you've checked that. In most cases, the shunt is sitting there grinning at you, just waiting to be fed with a blob of solder. No sign of any shunt can you recommend a better controller for more power?

If you change controller then it will also mean a compatible lcd is required, I doubt you will get a Bafang one on it's own. Bafang use Higo connectors (similar to Julet) except the pin outs are sequenced differently. It will mean you need new pas sensor and throttle and 1t4 or 1t5 trunk cable. You will need to get a KT controller one either 6 mosfet 17 or 20a but they do run hot if you climb slowly in PAS 5 or buy a 9 mosfet 22a on (which runs cooler), an LCD 3 will work with both.

October 14, 20196 yr Take the screws off the other end and the three along the side, then slide out the pcb and show us some clear photos. I've shown you the two types of shunt. It'll have one or the other. They're normally near where the black battery wire is soldered.
