Two-pack NP-FS11 replacement set

The Kastar kit supplies two 1900 mAh lithium-ion batteries and a dual-slot LTD2 charger. Each cell stores 7.03 Wh at 3.7 V and fits Sony NP-FS11, NP-F10, NP-FS10, NP-FS12, FS21 and FS31 packs. The bundle targets owners of compatible Sony Handycam and Cyber-shot models who need spare power for long shoots.

Sustained charging behaviour

The LTD2 charger delivers 4.2 V at 800 mA per slot whether one or two batteries are inserted, so simultaneous charging does not reduce per-cell current. Intelligent LED indicators show real-time capacity for each bay, letting the user monitor progress without interrupting the cycle.

USB power limits

The charger draws 5 V at 2–3 A (15 W maximum) through either Micro-USB or USB-C input, so any standard 5 V USB source can drive it. Output is fixed at 4.2 V 800 mA per channel; faster USB-PD profiles or higher-voltage inputs are not supported.

Questions about this item

Does the LTD2 charger get hot or draw much power when charging both NP-FS11 batteries all day?

The charger runs from a 5 V 2-3 A USB supply at up to 15 W and outputs 4.2 V 800 mA per battery, so heat and power draw stay modest during extended use.

What power source must I already own to run the LTD2 charger?

Any USB power adapter or port that can deliver 5 V at 2-3 A (15 W) via Micro-USB or USB-C will power the charger; a Micro-USB cable is included.

Will these 3.7 V 1900 mAh NP-FS11 packs work in my older Sony DSC-P30 that originally took NP-FS10 cells?

Yes, the batteries are listed as direct replacements for the NP-FS10 and NP-FS11 used in the DSC-P30 and other compatible Sony models.
