Kastar BT-65Q Li-Ion battery pack

This set includes three 7.4 V 5800 mAh lithium-ion cells and a matching AC wall charger. It is built for surveyors and field crews who operate Topcon total stations and data collectors throughout the day. The 42.92 Wh capacity supports extended measurement sessions without frequent swaps.

Foldable plug charger with LED status

The bundled charger accepts 100 to 240 V input and delivers 8.4 V at 600 mA through a foldable flat pin that stores neatly in a gear bag. A red LED shows active charging while green signals standby or a full cell. The compact 3 by 2 by 3 inch form factor keeps the kit light for transport between job sites.

Direct replacement for Topcon BT-65Q series

Each battery replaces the original BT-60Q, BT-61Q, BT-62Q, BT-65Q, BT-66Q and GMS-2 packs used in FC-200, FC-2200, FC-2500, GPT and GTS instruments. It also works with BC-30, BC-30D and BT-30 chargers. Buyers needing higher capacity cells or a multi-bay desktop charger will not find those options in this package.
