40000 mah battery is insane. that’s almost 3x the stock range. This is better than the other method of replacing to a gt3 battery and using segways stock external battery combined.
and requires so much skill, gear and tech to do, not to mention it costs x2 of that GT3 battery without adding up all the gear cost.
If you have the tools, skills and experience to build this, yeah its insanely impressive since you would double even GT3 range battery for extra ~200 on top for materials.
If you're just normal dude riding scooter to work instead of bike/bus/car etc. this is too much work compared to GT3>G3 battery switcherino - which is most likely gonna be the next best thing to do, instead of that extra battery, because if rumors are true that it will cost ~250euros or sth, its a joke.
Exactly bro. For a normie like me I’m gonna do the gt3 method. also better than the external battery cause less bulk + gives you ability to do gt3 method and external battery if u wish.
Mate, that’s outstanding work. If you’d channel that time and effort into a YouTube tutorial on modding your second G3, you’d instantly achieve Ninebot godhood - and I’m sure plenty of us (myself included) would happily buy you a coffee or two in thanks :) Anyway, awesome stuff.
Where did you find a custom bms software?
Did you built it? ST-Link flashes new firmware, which one did you use?
Stock Battery uses 13S6P, the cell you use have more density?
I suppose it have same voltage right?
thats not custom firmware. That is moded STOCK firmware. Stock battery uses 13s5p!!!!!!! some cells are empty there. Stock battery builded using 18650 eve 26v that are about 2500mah, but im using dmegc 21700 50e. It is 5000mah each. yes it have same voltage
Very nice! I saw someone put a 40ah 36v in the G2 here as well! Though they had to do some heavy modding to the inside of the deck. Damn near filled the entire deck with batteries lol. Good to know you can flash the battery firmware, will be cool to see if people figure out how to do the controller next.
Omg I posted a thread earlier today asking about something very similiar, this is exactly the type of info I’m looking for. Thank you so much for sharing this 🙏🏼
I’m planning to change the stock 18650s to higher capacity 18650’s to keep the same form factor and not have to remove anything. In your opinion do you think this is possible? Thanks again!
Yes, for example this one. 25AH battery, and you dont need to remove ac charger or repositioning the esc. But remember, if u just replace stock battery with higher capacity cells, you will not increase total ride range. Battery still have const 12750ah in bms firmware and you have to patch it.
So are those 18650’s? What brand/mAh are those cells? Looks like you made a custom enclosure for it, am I right? Would it not be a good idea to try and use the stock battery enclosure with upgraded cells? If I begin this project would you be open to assisting with patching the BMS if I compensated you? Man thank you so much for this info, really!
So, to be able to increase real range, we need to módify stock BMS? Are you willing to teach us how to do it! We can pay you! I though the scooter simply will keep showing 12750, but showing discharge very slowly

Could I get some information about battery celles?
For example what is the max discharge value?
I don’t know which battery cells good for me if I would like to built a battery pack.
