    QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

    Anyone find a 420 front sprocket that fits this motorshaft? Just built a second frame (w/ 5 more people wanting one) and now the 420 sprockets I have don't fit. I've ordered 6 different variations of the new specs from Amazon, but haven't found one that fits. A link would be super helpful...

    84v input to 84v output dc-dc charger

    I believe so, yes. I didn't build the packs myself, and haven't open them up to see. But yes, that is my understanding.

    84v input to 84v output dc-dc charger

    I bought a 72V inverter – 5000w, so I can run a heater, hair dryer, water heater, etc. This is a very cool setup for winter camping – no genny running or even wood stove in the tent, just a space heater. This is an added bonus, for sure, but ultimately, I want to be able to ride from camp, come...

    84v input to 84v output dc-dc charger

    The main reason is I own these two batteries. I designed an e-moto from the ground up, found a company that would build a battery pack for me (LG Lipo), but as things would have it, the bike design changed, and thus the batteries no longer fit. I have already spent the money on the packs, so...

    84v input to 84v output dc-dc charger

    I like this option best. Where would one find a current limiter? My current setup in my mind (the best way I understand it) would be this: - Trickle charger from the onboard genset – 84v5A. This will charge my "bank" continuously, being regulated by charger limiter, and also BMS. - Use an...

    84v input to 84v output dc-dc charger

    Hi guys... Long time reader, first time poster. I have a couple of batteries I'd like to use as a remote charging station for when I'm in the backcountry and would like to charge my e-moto. Here's my specs: Bike: 72V40ah battery (20s) Charge Pack: 72V80ah battery (two 20s batteries joined...
