Hi, long time follower first time poster.
I just turned a Razor into an electric scooter. Right now it's using a 60v 4AH battery pack from Walmart for $60 and a $200 scooter kit from L-Faster. The kit is an 8in 45mm 48v wheel and a 60v controller (100v capacitors) and throttle with LED readout with cruise control and regenerative braking (not hooked up). The scooter can do 54kph which is over 30mph however I am not stupid enough to ride it that fast, I've only gotten to about 30kph which was plenty fast for me. Anyway, the idea behind the build was to make everything as internal as possible and retain the functionality of the original scooter. After it's all said and done, it weighs 17lbs with the battery (battery is 4lbs).
I'm thinking about changing out the batteries for something that I can fly with (under 100wh per battery). I was thinking 2 24v Kobalt batteries are the next best thing in terms of price and performance.
I had a couple issues with this build that I'm working on, First it's very difficult to 3D print a enclosure for this battery, it's designed to slide in top down which means printing a huge ugly battery enclosure. I also have an error on my LCD screen it's E-07 (my kit came with no documentation), when I really gun the throttle on the scooter the motor makes noises and rapidly slows down (like braking), my guess is the motor isn't able to handle the extra voltage or that because it doesn't have a hall sensor it simply loses place?
So a few questions...
Assuming that the power tool batteries have BMS's in them, is it possible to charge them in series/parallel safely?
Could I use a 48v Charger?
Would 24v Kobalt batteries be a good choice for my application?
Any other battery alternative that would be safe for travel but isn't ridiculously expensive?
