Replacement Battery for Survey Handhelds

The KingSener BA7800S is a 3.8 V lithium-ion pack rated at 8000 mAh and 30.4 Wh. It serves as a direct replacement for the original BA7800 and BA7800S cells used in Stonex UT10, Unistrong RS60, GISBEE A8 and other compatible GNSS or GIS handhelds. Field crews who need a fresh, factory-new power source for daily survey work will find the correct voltage and connector match.

Fits Existing Chassis and Charging Dock

The battery slides into the same compartment as the OEM unit and charges through the device’s standard cradle or USB port, reaching a full charge of 4.35 V. No adapter cables, sleds or firmware updates are required, so the swap keeps the handheld’s IP rating and one-handed balance intact. It frees the user from carrying a bulky external power bank during long traverses.

Capacity and Runtime Headroom

At 30.4 Wh the pack delivers a full day of typical GNSS logging, screen-on navigation and radio telemetry on a single charge. Heavy continuous RTK streaming or cold-weather operation will drain it sooner, so crews planning extended shifts should carry a spare. It is not suited for devices that require a higher voltage platform or a larger form-factor cell.
