Offering two Kelly Controller brushless DC motor controller assemblies. The single-controller assembly features a KHB72701C controller rated for 24-72V and 700A. The dual-controller assembly features two KBL72301C controllers, each rated for 24-72V and 300A. I think these both have the CAN bus option included, but I don't remember for sure. The dual-controller assembly is completely new, never used. The single-controller assembly was installed and used only once for testing, and then removed. Asking $330 for each assembly, or $600 for both. Free shipping within the US and Canada. I also have one Control Box, which I'm happy to include for free with the assembly if you want it ($29 value).
