2.4 Power supply
N5 GNSS receiver supports internal batteries and external power input.
2.4.1 Internal batteries
The receiver is equipped with two rechargeable Lithium-ion batteries, which can be
removed for charging. The N5 receiver adopts the hot swap battery design that
provides you an effective survey workflow. The internal batteries typically provide
about 12-hour operating time as a rover, about 7-hour operating time if operated as
a base station with internal UHF Tx (transmit at 1-2 watts). However, this operating
time varies based on environmental conditions.
