I'm new here and new to ebikes in general so please excuse me if my questions are frustrating to some of you :|
I built an Ebike and it has two 48v 10Ah in parallel @20Ah total and they are the EXACT same battery from Viset with BMS. The bike has a 350w 15a controller that's rated at 19v/30v low voltage protection and a 1000w rear hub motor. I am going for a 35a controller and expect to have a decent acceleration increase with a slight speed increase. It appears to me that my controller is the bottleneck here so I should expect to see at LEAST a slight increase in everything. At least that's what I am hoping for lol
Specs in a nutshell.
Battery: Viset 48v 10Ah with BMS. 30 amp max continuous. 60+10 amp max peak current each. I have two in parallel for 20Ah.
Motor: 1000w rear hub. No details.
Controller: 350w 15 amp with 19v/30v low voltage protection.
My two questions are.
1) Will I get any speed increase going from 15 to 35 amp controller? I do understand that controllers don't necessitate a speed increase but going from 15 to 35 is significant to running my 1000w motor to it's full potential. I feel that enough force of acceleration will impact my speed to a degree and not just on hills, but tagging my 180 pound weight around easier which would have to give me a speed increase in some way. Right?
2) I have two batteries in parallel and they work great. Each battery runs at 30 amp max continuous and 60+10 amp max peak current. I know running in parallel gives double the amp hour. However, what about running them in a series instead? Technically that should take my voltage from 48 to 92 and give me a nice boost that way. Does that mean I would only get 10Ah? I also heard you can run in both Parallel and Series. Does a series affect the amp max continuous? (If that makes sense hehe)
Interesting side note, I went from a 350w motor to a 1000w motor and I got an extra 5mph with the same batteries and 15a controller. My max speed with the 350w motor got me to 20mph. The 1000w motor got me to 25mph. I expect with the new 35a controller to give me at least 30mph.
