Compatibility clearly identified: Wispeed T850.
Expert advice
Before purchasing, check the voltage indicated on the battery (36V) and the model number (Wispeed T850) to avoid any incompatibility. When replacing the battery, switch off the power supply, disconnect the battery and check the condition of the connectors and wiring harness (pins, oxidation, overheating): a damaged connector can cause similar failures to a controller. If you have any doubts about the connectors, or if several versions exist on your bike, carefully compare the layout and type of connections on the original controller before fitting.
