Kastar BT-65Q 5800mAh Li-Ion Kit

The Kastar BT-65Q kit supplies a 7.4V 5800mAh lithium-ion battery rated at 42.92Wh together with an AC wall charger. The charger accepts 100-240V input and delivers 8.4V at 600mA. A foldable flat plug makes the charger compact for transport and an LED shows red while charging and green when complete.

Survey crews needing a direct replacement

Field teams using Topcon total stations such as the GTS-750, GTS-751, GPT-7000i, GPT-7500, GTS-900, GPT-9000 or FC series controllers can swap in this battery and charger without modification. Users whose instruments require a different voltage, a proprietary docking charger or a higher capacity pack should look at other options.

7.4V 5800mAh lithium-ion chemistry

The single specification that decides fit is the 7.4V 5800mAh lithium-ion cell. If the original battery for the instrument matches that voltage and chemistry, this pack will power it; if the instrument expects a different nominal voltage or a nickel-based pack, this unit is not compatible.

Questions about this item

Does the 7.4 V 5800 mAh lithium-ion cell generate noticeable heat or noise during continuous all-day surveying?

The battery is a passive lithium-ion pack with no fan or moving parts, so it runs silently and produces only normal warmth under load.

Which Topcon total-station models must I already own for the BT-65Q pack to power them?

Compatible instruments include the FC-200, FC-2200, FC-2500, GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900, GPT-9000 and robotic variants.

Will the foldable-plug AC charger still charge older Topcon BT-60Q or BT-61Q packs I keep as spares?

Yes, the charger supports the BC-30, BC-30D and BT-30 charging standards used by those earlier batteries.
