Warm tips:

1. Successful start-up of the drill requires 2pcs 10℃-20℃ power batteries, 4pcs 5℃-10℃ power batteries (recommended power battery models: for Sony VTC4, VTC4A, VTC5A, VTC6), 0V and 8.4V connections, Using copper wire of more than 2 square millimeters.
2. Connect 0V, 4.2V. 8.4 volts, 8.4 volts strictly according to this figure. When soldering the wire, you cannot touch any on-board components, and do not intentionally short circuit.
3. When soldering or charging batteries, as long as one battery exceeds 4.2V, *430″ resistance will heat and discharge (discharge to 4.19V or so stops heating). If the “430” resistor is heated seriously (too hot to touch), Please check if the wrong connection is made.

Note:
Please allow 1-3mm differences due to manual measurement.
Due to the different displays and different lights, the picture may not show the actual color of the item. thanks for understanding
