Questions about this item

How do I install the 7.4V SM-2P plug battery in my Stadie water gun, and what step is often missed?

Align the SM-2P connector with the gun's socket and press firmly until it clicks; the step often missed is verifying the polarity matches before forcing the plug in.

What maintenance will the 2600mAh lithium-ion pack need later?

After 2 or 3 full charge and discharge cycles the pack reaches peak capacity; thereafter store it around 50 % charge if unused for weeks and avoid temperatures above 60 °C.

What limit appears first during a long water-gun battle with this 19.24Wh battery?

The 2600mAh capacity sets the run-time ceiling; sustained high-current trigger pulls will hit the pack's over-current protection before the voltage drops to the 3.7 V nominal floor.
