Three-battery pack with LCD USB charger

This set supplies three 7.4 V lithium-ion batteries rated at 5800 mAh each, plus a charger that can replenish all three units simultaneously. It is intended for survey crews who need reliable power for Topcon total stations during extended field sessions.

42.92 Wh capacity per cell

Each battery stores 42.92 Wh, the single figure that determines whether the pack meets the energy demands of a given instrument. If a job requires more or less runtime, this capacity is the decisive specification.

USB-powered charger frees AC outlets

The LTD2 charger draws 5 V at 2 A from any USB wall adapter, vehicle port or computer, delivering 8.4 V at 0.5 A to each of its three slots. An LCD panel shows real-time status so operators can manage rotation without mains power. Not for users who need a direct AC-input dock or support for non-Topcon battery mounts.

Questions about this item

What does the 42.92 Wh capacity mean for field use?

The 42.92 Wh rating at 7.4 V equals 5800 mAh, giving a full day of power for supported total stations such as the GTS-750 or GPT-9000.

How does the USB charger limit charge speed?

The LTD2 charger draws 5 V 2 A from any USB source and delivers 8.4 V 0.5 A to each of three bays, so all three batteries charge together at 0.5 A per bay.

Will the charger and batteries fit in a standard survey kit case?

Each battery measures 3 by 2 by 3 inches and the charger is a compact LCD USB unit with three bays, designed to sit beside the instrument in a typical case.
