Kastar 4-Pack Battery and LTD2 USB Charger Replacement for Sony

In this review the Kastar 4-Pack Battery and LTD2 USB Charger is evaluated for videographers and camera owners who need reliable spare power for older Sony camcorders. The bottom line is clear: this bundle provides four 7.2V lithium-ion batteries and a flexible USB-powered charger that can fill two cells at once, making it a practical choice when original factory batteries and chargers are no longer available. The package is aimed at users who value capacity and convenience over brand-new OEM accessories.

Key Features

• Battery Capacity: Each 2650mAh lithium-ion cell offers extended run time compared with many original low-capacity replacements, reducing mid-shoot swaps.
• Dual Charging: The LTD2 USB charger can charge two batteries simultaneously, which speeds turnaround when multiple spares are in rotation.
• Flexible Input: With Micro-USB and Type-C input options and a Micro USB cable included, the charger can be powered from portable battery packs or USB wall adapters for field use.
• Interchangeable Plate: The charger accepts different plates to fit several Sony NP-FV series batteries, so it works with multiple battery models without buying extra chargers.
• Visible Status: The intelligent LED display shows charging status and relative battery capacity, letting the user know when a cell is ready to go.
• Practical Output: The charger outputs 8.4V at 800mA per channel, a suitable charging rate for these 7.2V packs without excessive heat.

Who It's For

This kit is best for owners of legacy Sony camcorders and cameras that use NP-FV batteries who need an affordable set of spares and a compact charger for travel or fieldwork. Content creators who shoot for extended periods or who swap batteries frequently will appreciate having four cells ready and the ability to charge two at once.

It is less suitable for users who require direct OEM warranty support or integrated camera charging solutions; professionals who need fastest possible recharge times or a single-manufacturer service plan might prefer official branded options.
