I have a great friend, who had a go at it for me, even though its not his bag, but I believe his work has come loose as he put new hall sensors in and did his best to fix it for me. Testing wise. took all installation off...

    The buggers stole my beast. Got it back no thanks to the Police. (long story) but I found it some young scallywags back yard, by peering over fences on local estate. Bingo! Trouble is they have raped it, they could not get it fired up so just cut the electric bits away. (I nearly cried!) So...

    LiPo to Li-On Battery swap out.

    I have sketched out the battery. The sketch is for one side of my pack, so I will just mirror this. Giving me 16s 6p I have not a clue on correct BMS or charger. If anybody could help? It would be really appreciated.

    LiPo to Li-On Battery swap out.

    A massive thanks for the Input. I see now 24s 4p is "mental" and is close to the controllers maximum. So because my Lipos were total of 62V. I will go for 16s x 6p. 60v 20 ah. That will allow for voltage drop as motor is 48V ? I am happy with 30 miles range and a speed around 28 to 30 mph. My...

    MAC 500/1000W MOTOR Grinding

    Done a rebuild. The grinding has gone, but motor is stalling, then the humming. Spin wheel backwards and yet can get motor revving correctly. Soon as under load motor does the above again. I go over a bump and it kicks in, then loses it again. Its the hall sensors. As you can see from the my...
