Hi all,
I recently entered the world of ebike customisation. Without really understanding how batteries work.
I purchased a Samebike L026, 500w (hub motor) which came with a stock 48v 10.4ah battery, last year. I recently decided that there was not enough power for hills or even flats, at least to support my weight of 90 kilos.
I wanted to buy a new bike, but fancied my chances at upgrading the Samebike instead. I watched countless Youtube vids (as you do), and went and purchased a:
Bafang 48v 1000w BBSHD motor.
I have charged the battery a few times now and on the Bafang 850C display, it only ever charges to 65% and never beyond. I assumed that this was because the controller on the motor had a different set up to the original Samebike controller, and also the bafang motor is compatible with a 52v battery. I also thought that my meagre 48v 10.4ah battery wasn't enough to power the motor sufficiently? I could almost live with that, but when I went for my first ride with a fully charged 65% of power, as I was cycling, the battery percentage dropped really rapidly, I couldn't travel too far as the battery was due to run out of charge. I managed a couple of miles, and returned home with 10% of battery life remaining. From 65% to 10% in not even an hour of riding.
Please help. Do I require more than 10.4ah's? I thought the motor would work with a 48v battery, the motor says it is a 48v 1000w motor.
I would appreciate any help. I am a battery noob, so please explain to me as though I'm a complete novice (which I am). Other than the battery power and depletion issues, the bike rides infinitely better than it did with the original Samebike hub motor.
Regards and thanks
Frank
