BAT-W01-A
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.

LED and Power Behavior
| USB-C PD Charger NOT plugged in | System is OFF |
| Battery charging, USB-C PD Charger plugged in, Battery capacity < 5% | Fast blink RED LED |
| Battery charging, USB-C PD Charger plugged in, 5% ≤ Battery capacity < 60% | Medium blink YELLOW LED |
| Battery charging, USB-C PD Charger plugged in, 60% ≤ Battery capacity < 100% | Slow blink GREEN LED |
| Battery fully charged, USB-C PD Charger plugged in, Battery capacity 100% | GREEN LED is SOLID ON |
| Press PWR Button - ON mode | Solid YELLOW LED is ON and user shall hold the PWR button. Then solid GREEN LED is ON and user can release PWR button anytime then |
| Press PWR Button - OFF mode | Solid RED LED is ON and user shall hold the PWR button. Then RED LED will go off and user can release PWR button anytime then |
| Battery's temperature exceeds battery warm threshold or battery cool threshold | RED and GREEN LED blinks alternatively |
|
a. Battery's temperature exceeds battery hot threshold or battery cold threshold
|
RED LED blinks twice consecutively then GREEN LED blinks twice consecutively and repeat |
Special Safety Features
| Detachment Protection | Auto power OFF battery box when the battery box is accidentally detached from Wearable MR radio during normal operation |
| Preventive Power Cycling | Battery box will be forced to enter power OFF mode whenever there is no detection of Wearable MR radio even if the power ON button is pressed |
| Forced Manual Shut Down | Battery box will be forced to enter power OFF mode in the event of long press of power button |
