Replacement battery for Topcon survey instruments
The Kastar BT-65Q is a 7.4V 5800mAh lithium-ion cell delivering 42.92 Wh, designed to replace the Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q, BT-66Q and GMS-2 packs. It suits surveyors who need a direct swap for total stations such as the FC-200, FC-2200, FC-2500, GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900, GPT-9000 and ROBOTIC models. Buyers whose equipment uses a different battery form factor or voltage should look elsewhere.
LCD USB charger powers up to three cells
The bundle includes a compact charger measuring 3*2*2 Inch that accepts 5V 2A via Micro USB from a wall adapter, vehicle socket or computer. Intelligent LCD readouts show charging status and remaining capacity for each bay. Output is 8.4V 0.5A per channel, allowing three batteries to charge simultaneously. Users without a convenient USB power source will need to provide one separately.
Verify your instrument model before ordering
Compatibility is limited to the Topcon battery, charger and total station models listed above. No other brands or series are supported. Confirm that your device accepts a 7.4V Li-Ion pack and that you have access to a 5V USB supply for the charger. If your instrument requires a different chemistry, voltage or connector, this kit will not work.
