The Bosch BES3 Adapter allows you to easily and reliably test Bosch Smart System (BES3) batteries, including the PowerTube 800 BES3.
With some batteries, the standard test frequency may cause early shut-off. Using the latest software (v8.9.0.9) and integrated firmware update (v9.03), this issue can be solved by enabling the PWM-High option.
For full functionality (100%), we recommend always using the adapter in combination with the free PC Software.
