Hi. Sorry for the long post.
I ordered a complete 1000w Bafang BBSHD kit with a 48v 17.5ah battery and a dcp18 display from China.
I did a lot of research before choosing the display, battery and BBSHD. I actually wanted a 52v battery, but from what I read, the dcp18 display is inaccurate with a 52v battery, so I went with a 48v battery instead. I was also worried about longevity of the motor, so I figured its better to be safe.
The ebike Im building is supposed to be a complete replacement for a car and public transport.
I haven't started to install the motor kit on my bike frame, I just connected the battery to the motor and the display and I connected the throttle just to check if everything is working. I have encountered som issues.
My battery although it is according to the seller, 48v 17.5ah with 18650 Samsung cells, it only charges up to 54.1 and rops to 53.6v within a couple hours when turned off and not used. Seller says this is normal, is it?
When my battery is fully charged, the display shows 65% battery remaining. From what I read, this wasn't supposed to happen with a 48v battery, only with a 52v battery. But my seller says it's the opposite. A 52v battery will show accurate readings on the display, while a 48v battery will be inaccurate. Is this true?
The seller says that Bafang has upgraded to a 52v controller, so thats why my I'm having battery compatibility problems. Is this true? Any way to verify that the controller is 52v? And even if it is, does that mean the display cant show accurate readings for 48v battery, just because the controller is 52v?
It actually says 48v 1000w on the bottom of the controller, when I showed it to the seller they said its 48v and 52v universal. Dont know what thats supposed to mean, but anyway. I should be getting correct battery readings with a 48v battery right? So since I am not, it means that either Something is wrong with the battery, the display or the controller itself, right?
With PAS set to 1 on eco mode, the display estimates a range of 21km, with PAS set to 5, it estimates 16km. This cant be right. Is it? I expected a minimum of 50km range. My 374wh kickscooter with a max speed of 32km/has a 50km range on paper, and I get about 15km out of it on sports mode riding at 25km/h + most of the ride. I guess it could do 30km on normal mode. 48v, 17.5ah is 840wh. Roughly, my ebike should be able to do 50 km on eco mode without pedaling. 16-21km on eco mode can't be right. Can it?
