Re: UK plug charger for Luna Cycle Mighty Mini

Don't they use the IEC connector on the charger itself, with a separate cord? If so, you can simply use the cord off of anything else that has that same plug (must be a lot of stuff out there).

Re: Prodeco Phantom X2 folding bike

Well, the colors on the wiring harness might match the original throttle wire colors, but there's no reason they would match any other throttle (there is no "standard"). Commonly, from the throttle, red is 5v, and black is ground, and whatever is left is the throttle out signal, but those are not un...

THrottle voltage varies normally and smoothly, even if I tap on it, so it's not something in there causing it. HOwever, the problem *is* worse teh lower the battery voltage gets, though it does not sag enough to be causing this, from waht I can see on teh CA display. I rechecked all the cell voltage...

Re: About Cycle analyst

if the controller already has an internal shunt, would not the external added shunt (from CA) just ad a little more resistance to de circuit? It's so small it's irrelevant. Then, at the V3.0 installation manual it say you just have to plug the throttle cable from the CA to the controller, but what ...

Re: Prodeco Phantom X2 folding bike

Prodeco is your best bet for wiring diagrams. Perhaps the original owner may still have the original battery; even if it's dead you can open it up to determine wiring. If it didn't originally have a throttle, and just used PAS, you may have to change to a different controller to be able to add one. ...

Re: [Help Requested] Reverse-Engineering an undocumented conversion kit

Many (most) common ebike controllers are not FOC; they just use the phases and halls to control the motor. (or just phases, no halls, running entirely sensorless). Some work better than others, and some work better with some motors than ohters, but mostly they just all work. Most of them are trapezo...

Another option is to build your own large hub with lots of room inside, with a plate mounted to the axle for bolting motor batteries and controller to. Then put teeth on the inside of the rotor (spoke flange), and use a small motor with matching teeth on it's shaft to drive the hub from inside. Migh...

Loose sense wire or cold solder joint on the BMS could do it, if the BMS shuts off whenever it loses votlage on the sense wire (some of them just ignore that wire compeltely if there's zero voltage on it, which is why some packs die of overcharging or overdischarging a cell group when sense wires br...

Re: Adding PAS to EM3EV controller

As noted in your other thread, you CANNOT connect the pulse-type PAS directly to the 6-pin CA connector, and have it work as a normal PAS. It will NOT work to run the bike like you want it to. You will have to either use the CA or some other device to interpret the PAS pulses into a throttle signal....

Keep in mind that a 10Ah pack run at 3C is only going to last 20 minutes at that rate. But that *should* be long enough, at 15-20MPH, to cover a round trip of 4-5 miles, easily enough. If you need 30A continous, Headway may not be a good option. They claim high C rates, but may heat up too much runn...

Re: I bought an E Bike for my wife but she says its to slow

If the kit came with a regular throttle, you just replace it with your thumb throttle (unless you want both, in which case yes you'd use a y-cable). If it did not come with a throttle, then you would need to find out if it has a throttle input (not all kits do). If it does not, you may not be able t...

Re: Charging amps through JST balance wires

That's how almost all balancers work--they drain high cells, then restart charging, etc. It can take days, even weeks, for a badly balanced pack with bad cells to rebalance, and as soon as the pack is used again it's going to unbalance a little, and the more capacity is used, the deeper the discharg...
