Kastar BT-65Q Li-Ion Power Kit

Four 7.4 V, 5800 mAh lithium-ion batteries and an LCD USB charger arrive in one pack, giving survey crews a ready-to-go power supply for compatible Topcon total stations and data collectors. The set replaces original BT-60Q through BT-66Q cells and works with BC-30, BC-30D and BT-30 chargers.

Suits field teams needing multiple hot-swap packs

Crews running GPT-7000i, GTS-750, GTS-751, GPT-7500, GTS-900 or FC-200/2200/2500 instruments can keep two batteries charging while two stay in the field. Users whose equipment demands a different voltage, connector or form factor should look elsewhere.

Each cell stores 42.92 Wh at 7.4 V

The 5800 mAh rating decides whether a full day of measurements is possible on one battery; the charger delivers 8.4 V at 0.5 A per slot and shows status on its LCD, so you can confirm charge level before leaving the site.
