I'm a newbie to the electric bike world. I just purchased a CS(brand) ES-101(model) i believe. It doesn't actually say in my user manual, if that's what you wanna call it, nor does it on the ownership tag.
When I lift the seat there's a white "control module" looking box and my battery pack.
The battery box is all one big black unit, with a plug on it that leads to the control module.
On the control module it says that it's a 48volt, 500watt scooter.
I've got it up to roughly 28-30 just the way it is. Luckily for me it's chain driven, so I am going to be changing the sprockets to receive more speed. However I would like to increase the longevity of my bike. The charger auto shuts off when charged, so it says, and I got roughly 15 km's our of it before it would no longer even go over 12.
I would like to know if there's something I can check to see if one of the cells in my battery has died, or add a second battery, or set of batteries to increase the longevity as it's supposed to get at least 40 - 50 km's to a charge.
Any advice, tips, help would be greatly appreciated.
I do know the differences between ac, dc, series and parrellel and know a fair bit about electronics. Just unsure about these bikes and certain specifics with them like the controller.
