Three-battery kit with dual USB charger

This set includes three 7.2 V lithium-ion batteries rated at 2200 mAh and a compact LTD2 charger that powers two cells simultaneously. The charger accepts 5 V 2-3 A input through either Micro-USB or USB-C and delivers 4.2 V at 800 mA per slot. An integrated LCD shows real-time capacity and charging status for each battery.

Replaces individual OEM cells

Photographers carrying a single original battery gain two extra 15.8 Wh packs and the ability to replenish pairs at once, cutting downtime between shoots. The swap is worthwhile when a day’s work exceeds one battery or when travel limits access to wall outlets. Users who rarely deplete a single charge will see less benefit.

Plug into any 5 V USB source and insert cells

No tools or firmware are required; the charger auto-detects inserted batteries and begins charging. The only common issue is attempting to charge with a low-current port below 2 A, which slows the 800 mA output or prevents dual-bay operation. Ensure the supplied Micro-USB cable or an equivalent Type-C lead is used for reliable contact.
