voltage

I was curious what impact the voltage reading on the onboard display may have on range. I have 2 step thru xp 2.0 bikes and both seem to show around 53.6v on a fully charged battery. My voltmeter shows closer to the expected 54.6v. If the display is reading 1v low, does that mean I lose some...

Hi, I have a BBS02b kit installed on my bike since a while. Recently I had problem with motor and display switching off abruptly. I'm trying to understand where the problem comes from. It seems to me that the problem is battery voltage drop too much under load. I would like to know if the...

I've been searching for a chart that converts battery voltage into a percentage, and have found some for 48v. But it doesn't show what Ah the chart is for. So I'm wondering if there's any difference in voltage between two 48v batteries that have different Ah? I have a Yonglin 80c display where...

I came across a huge supply cell-protected, 3.7 volt Li-Ion batteries for dirt cheap, (10 bucks for 100 batteries) and they are all good. So I want to use them to make a custom battery pack for an ebike. The issue is, 3.7 volts doesn't multiply neatly to 24 or 48 volts... I could stack 8...
