Replacement Power Kit

This Kastar kit supplies two lithium-ion batteries rated at 7.4 V and 5800 mAh each, plus an AC wall charger with a foldable flat plug. The set replaces Topcon BT-60Q, BT-61Q, BT-62Q, BT-65Q and BT-66Q cells used in survey total stations.

Build Integration

The charger accepts 100–240 V input and delivers 8.4 V at 600 mA, so it plugs directly into site power without a separate adapter. LED indicators show red while charging and green when the batteries reach full capacity, freeing bench space for other instruments.

Buyer Fit

Survey crews running Topcon FC-200, GPT-7000i, GTS-750 or GTS-900 series units gain a ready spare pair for long field days. Teams needing higher capacity cells or a multi-bay charger for more than two batteries should look elsewhere.
