Hi, My battery pack is a 22s 5p, made of 26650 cells. Each cell is capable of 25amp continuous and 50amp burst. This feeds into a 150amp ANT BMS. Supply is protected by 100amp fuse. As stated in my post, the wiring is correct, I have checked it many times and this is not the first e bike I have buil...

Hi, I have just completed my new build. I don't want to go into a lot of details, but I am not getting any power to the motor. I have one of those Chinese hall testers. Using that, Motor phases are ok. Motor halls are okay. Plugged into controller, I am not getting any throttle reading. I am using a...

Thank you very much for the advise.

Sorry for all the questions, but one last one. From the controller I have a yellow and red wire in a plug labelled ignition. If I understand the wiring diagram, then the red is battery voltage from the battery supply to the controller and the yellow is battery voltage when connected to the red wire....

Okay.
Thank you very much for the advice.

Okay, thank you. Sorry my post was not clear. My set up is, 12v key switch to precharger. This uses a resistor to charge up capacitors. When charged, the precharger sends 12v to the relay, that then connects the battery to the controller. My question is whether I could connect the ignition power to ...

I am just finalizing my build. I am wiring in the 18F 8kw controller I bought a while back. I have a pre charge system set up. It checks the circuit then charges the capacitors and then switches the relay for main power. This is controlled from a 12v key switch. My question is, can I use the relay p...

I am in the process of building a Stealth type bike. I am using your 7kw controller. My battery pack will be 5p22s (But running at 80% - 90volts), which will be 25amp and 250amp burst capable. My question is, do I need to build a pre-charge circuit to the controller to protect the caps on battery co...

Hello, Quite sometime back I bought your 18fet 7kw controller with built in blue tooth. I am still in the process of building my bike, but am getting quite close to finish. I have a question about the power handling of the controller as I am a little confused. It stats 70amp max and 200amp phase cur...
