A flat-top IMR 18650 battery, measuring no more than 65.5mm in length, and with a max. continuous amperage of 20Amps or greater, is required.
To charge the SERIES-B Tilt 50W, attach the Micro USB charging cable to the Micro USB port found on the base of the device. While the battery is charging, a charging symbol will appear on the LED screen. Once the battery is fully charged, the SERIES-B Tilt 50W will cease drawing power, but the Micro USB charging cable should still be removed as soon as possible.
DO NOT FORCE the charging cable into the charging connector. It only needs to be inserted far enough that the charging symbol appears on the LED screen. Applying excessive pressure will cause damage to the device.
Alternatively, external IMR battery chargers are available to allow independent charging outside of the device. These external chargers are useful for if you have multiple IMR batteries as they allow you to always have a charged backup battery on hand! If using an external 18650 battery charger, please be sure to follow the device's instructions.
Pass through function
While the device is charging, it can still be used as a pass through (i.e. it can be used and charged at the same time). This function requires a suitable 20Amp IMR 18650 battery.
If you're regularly changing your IMR battery, please see this video to ensure that you're removing the battery safely:
