Your likely not going to like the answer here but you must spend about $2000 on a upgraded battery for your controllers output to be anything better then the stock controller. Here's what a lot of sellers selling asi controllers fail to tell people is that the asi bac4000 while it can output more kw the motor phase amps are actually not that much higher then the stock controllers and I have a feeling one of these days someone will hack the stock ones to get them outputting more power. I personally own 3 asi controllers from the bac855 for a bbshd ebike to the bac2000 and bac8000. I personally hate the company asi because of.how they do business and treat their customers they make it so hard to get the software to tune the controllers on the phone yet give it away for the computer so what's the big deal there u ask well I don't know. It's ridiculous. Also the stock battery only will support 80amps maybe 85 continuous before the bms will cut the power and doing a bypass only unlocks around 100-120amps max 100amps is more realistic and your going to hurt the battery pushing it any harder. They make tons of great after market batteries from many companies, ebmx, lite speed bikes, chi battery, surron shop, emoto bros all make better batteries for the surrons and segways. Go for the 72v and biggest one they make. It might stick out the top of the battery compartment but if that bothers you there's ways to hide that better by raising the seat and the latch for the battery lid a bit and removing the bottom battery tray to make more room so it will fit and retain mostly a stock look. Don't go 60v what ever you do unless that is really important to you to have that particular voltage (some people it's important for example if they plan to keep stock controller or charger) but 72v is where.you will see huge gains in speed. If you can find it (most likely hard to find) getting a higher then 72v battery is possible and your controllers capable of handling I think a max fully charged battery voltage of either 88v or 100v one of the two. The higher you can manage to get the voltage the faster your top speed will likely be while also keeping the motor cooler too.
Sorry, there was a problem. Please try again later.buy the 25 dollar Battery bypass kit. it will get you more out of your stock battery before investing 2k into a battery
Sorry, there was a problem. Please try again later.72V
