I recently bought a Buffalo A3. It has a defective battery so it only last about 2 km. Its a 22V 4.4Ah battery. I am looking for a new one and found an interesting 6s5p on aliexpress. I am thinking it should be an easy switch. I’ll have to come up with a new enclosure but I have a 3d printer so that wont be much of an issue. The only downside to this battery is probably the way the cells are positioned, making it very bulky. But it will fit the board. I just want to make sure it will work.
