Three-Pack Lithium-Ion Replacement

This pack contains three Kastar BT-65Q lithium-ion batteries rated at 7.4 V and 5800 mAh. Each cell stores 42.92 Wh of energy. They are built as direct replacements for Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q, BT-66Q and GMS-2 packs used in survey total stations.

Charger and Instrument Compatibility

The batteries work with Topcon BC-30, BC-30D and BT-30 chargers. They power FC-200, FC-2200, FC-2500, GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900, GTS-900A, GPT-9000 and GPT-9000A robotic total stations. Units that require a different voltage or connector will not operate with this pack.

Capacity Decides Field Time

The 5800 mAh capacity determines how long a station can run between charges. Survey crews needing extended operation without battery swaps should verify this figure against their daily workload. Teams that require higher capacity or a different form factor will need an alternative solution.

Questions about this item

Should I pick the 3-pack or buy single cells for my Topcon FC-200?

The 3-pack gives you three 5800 mAh 7.4 V cells in one box, so you can keep one on the instrument and two charged spares without ordering again.

How long will a 5800 mAh 7.4 V cell run my GTS-900 total station in the field?

At 42.92 Wh each, a single battery typically powers a GTS-900 for a full working day; the three-pack covers multi-day surveys without recharging.

Will these BT-65Q packs charge safely on my existing BC-30D charger?

Yes — the cells are built for the Topcon BC-30/BC-30D/BT-30 chargers and include over-charge, over-discharge, over-voltage, over-current and over-heating protection circuits.
