Ubidium uses smart 94 Wh Lithium-ion batteries which are installed into the Battery Compartments. 

RACE RESULT batteries contain a custom firmware adapted specifically to the requirements of the system and can be purchased either directly through the RACE RESULT Shop or through www.inspired-energy.com (request product number NH2054RR34). An alternative battery, from RRC Power Solutions, is compatible with Ubidiums running firmware version 1.5.2 and above.

The batteries will be charged by the system when connected to an external power supply. 

Batteries in Ubidium are "hot-swappable" meaning that they can be removed and replaced without the system shutting down provided that at least one battery or external power supply remains connected. 

Each battery contains an LCD display on the front to indicate the remaining charge. 

Battery Level	Indicator

Expected battery life is as follows according to the number of batteries and different use cases.

	1 Battery	2 Batteries	Power Consumption*
Active Timing (50 % Loop Power)	13.4 h	26.9 h	7 W
Passive Timing (4.6 m Antenna / 6 Segments)	6.7 h	13.4 h	14 W
Passive Timing (7.7 m Antenna / 8 Segments)	4.7 h	9.4 h	20 W
Passive Timing (15.4 m Antenna / 16 Segments)	2.8 h	5.7 h	33 W
Passive Timing (23 m Antenna / 30 Segments)	2 h	4 h	47 W

*Not charging, 4G upload enabled, no ethernet.
Power performance may be reduced above 25 °C (77 °F) / in strong sunlight.

Due to manufacturing processes and differences in the internal cells, the exact capacity of each battery may vary, the exact capacity of each specific battery will be shown on the smaller product label on the rear of each battery. This will always be 94 Wh or higher, but should never exceed 100 Wh in order to comply with international safety regulations.
