Yup, dido, What @strattos says is exactly what happened when I swapped out the stock battery for a 10s3p 30q pack. Speed wasn’t incredinly faster but it was noticeably better, range and not getting sag as quickly as I did or as bad were the big changes that are noticed. Those motors and the esc they use aren’t terribly bad. About to dig my koowheel motors and esc out of the bottom of my garage and scrape off the year old dust to make a little mini cruiser for when I walk my frenchie around my condo complex just cause, why not have a 4th or 5th if I have the parts to right…? Lol.
PS - I also friend 2 koowheel batteries just cause I was riding full throttle all the time and live in a hilly area and good luck on getting a replacement one from koowheel depending where he got it originally. I was lucky enough to buy mine from Jerry @ carvon and he just stopped by my house a couple days later and swapped it out for me and dealt with koowheeel himself., Super cool of him.
