This controller utilizes a direct die-to-chassis thermal bridge system . Instead of relying on thermal paste that dries out, the IPX956’s power stages are soldered directly to a copper-core inset within an extruded, finned aluminum housing. In stress tests, the IPX956 maintains operational temperatures 18-22°C lower than the IPX855 at equivalent load (1500W continuous). ipx956 better

For the rider, this means no more “thermal rollback” halfway up a mountain. You maintain peak horsepower for the duration of your battery’s charge. If you live in a hot climate or ride heavy cargo bikes, this thermal superiority alone justifies the upgrade. Many controllers claim to use Field-Oriented Control (FOC), but most use a cheap, modified trapezoidal wave that introduces a “cogging” feel at low speeds. The result? Jerky starts and a motor that sounds like a angry swarm of bees. Have you switched to the IPX956
