USB-C charging and safety circuits

Every battery integrates a USB-C port that accepts a 5 V 2 A adapter so it can be topped up without a dedicated dock. An LED glows red while charging and turns green when full. Built-in protection guards against over-charge, over-discharge, over-voltage, over-current and over-heating, and the cells meet UL 1642 and CE standards.

2280 mAh capacity per cell

The headline figure is 2280 mAh at 7.2 V, giving 16.4 Wh per unit. Buyers who need higher capacity per battery or a different form factor will not be served by this pack.

Questions about this item

What does the USB-C port on the Kastar NP-FZ100PRO charge at?

The USB-C port charges the battery from a 5 V 2 A adapter; a red LED shows charging and a green LED shows full charge.

What are the physical dimensions of each NP-FZ100PRO battery?

Each battery measures 3 by 2 by 3 inches, matching the Sony NP-FZ100 form factor for the listed Alpha and Cinema cameras.

How do you charge the Kastar NP-FZ100PRO batteries, and what is the common mistake?

Plug a 5 V 2 A USB-C charger into each battery; the common mistake is using a lower-current USB port that cannot supply 2 A, so the LED stays red.
