Questions about this item

What voltage does the 1800mAh cell deliver for the 7050 and 7059 models?

The replacement battery supplies 3.6 volts, matching the original specification for the 7050, 7059 and Black Knight M9 devices.

What physical size and connector does the 7050 battery use so it fits the Black Knight M9?

It matches the original pack dimensions and uses the same two-pin JST connector, so it slots into the M9 PN 75175 compartment without modification.

How do I install the Cameron Sino 7050 pack, and which step do people most often get wrong?

Open the battery door, unplug the old pack, connect the new JST plug observing the red-positive orientation, then close the door; the common mistake is reversing the polarity.
