A green light means the battery is charged.

Question edited for a lot more clarity. Question moved from 'Power Computers' to model category. Did you just remove the lead acid AGM batteries and replace with Lithium Ion? There is a lot more to it that that, you have to replace the controller as well and for safety you need a LiFePO battery and a new twistgrip because the old one is little more than an On / Off switch..

Have you tried removing plastic chain guard and making sure chain is not off track i had this problem and that is all it was.

I think you can a new dirt bike charger easily on Amazon or on the razor website. Be aware of how you use the battery though, it is the same idea for a lot of mobility equipment (electric scooters, electric wheelchairs, electric bikes, and etc...). You need to use the battery PROPERLY. For example, charge them from time to time, don't leave them there for a long period of time just because you don't need to ride out your electric dirt bike. Your battery's longevity will get hurt. Also, protect it from water and dust. I learn a lot more about outdoor sports equipment on this site: https://mobilityseeker.com/.
