Four-Battery Pack and Dual Charger

The Kastar FNP120 set supplies four lithium-ion cells rated at 3.7 V and 2300 mAh each, giving 8.51 Wh per battery. A single LTD2 charger handles two batteries simultaneously and accepts both Micro-USB and Type-C power inputs.

Thermals and Power Draw

Charger input is rated at 5 V with 2-3 A draw for up to 15 W, while each output channel delivers 4.2 V at 800 mA. The intelligent LED display shows real-time charging status and remaining capacity without audible fans or active cooling.

Build Integration

The compact charger measures 5*3*3 Inch and includes a Micro-USB cable, so it fits easily in a camera bag and draws power from common USB sources. Swappable plates let the same unit serve other compatible battery types, freeing you from carrying multiple dedicated chargers.

Questions about this item

How do I install the Kastar FNP120 batteries and LTD2 charger, and what step do people often miss?

Insert each 3.7V 2300mAh battery into the dual-slot charger, connect the Micro-USB or Type-C cable to a 5V 2-3A power source, and ensure the interchangeable plate matches the FNP120/DB-43/D-LI7 form factor; the LCD will then show charging status and capacity for up to two cells at once.

What maintenance or replacement will the Kastar FNP120 pack need later?

The four 8.51 Wh lithium-ion cells will gradually hold less charge after hundreds of cycles; when run-time drops noticeably, replace the affected battery with another FNP120-compatible cell — the charger and its swappable plate remain usable.

What limit appears first during sustained use of the Kastar LTD2 charger?

The charger outputs 4.2V at 800 mA per slot, so two batteries charge simultaneously at that rate; total input is capped at 15 W (5V 3A), meaning a depleted 2300 mAh pack needs roughly three hours per pair before the current taper begins.
