Rugged, Rechargeable Li-Ion Battery Pack


Doodle Labs' battery pack is designed to be used with our Wearable Mesh Rider products. The battery pack attaches securely to the Wearable Smart Radio using a custom developed simple Lock/Release mechanism for vibration resiliency. It uses an IP67 rugged aluminum casing which is verified to MIL-STD-810H standards.

The battery pack is fully USB-PD compliant and also supports a standard 5-V to 15-V power supply, so it can be charged by a wide variety of chargers for cell phones, laptops and even the USB port of a vehicle. The battery pack uses a smart battery management system (BMS) which supports fast charging and is large enough to support several hours of continuous operation.
