Smart Li+ Charger

A smart charger for lithium batteries, built around a recent, advanced US-made chip.

Why it is smart

• Charge check: if the gun's battery is above 7.6 V, still enough for a few games, charging does not start. To charge anyway, connect the tagger first, then plug the charger into the mains.
• Longer battery life: no overcharging, and capacity is preserved.
• Safe charging profile: it never exceeds safe current and voltage, so it can even recover deeply discharged batteries.
• Trickle mode: when full, it switches to micro-currents that stop self-discharge.

8.4 V, 0.6 A, 10 W; for 0.75–3 Ah batteries.
