Kastar 3-Pack BN-VF707 Battery and LTD2 USB Charger - Reliable Power

In this review the Kastar 3-Pack BN-VF707 battery set with the LTD2 USB dual charger is judged as a practical, camera-focused power solution for JVC GZ series users who need spare capacity and flexible charging. The review finds the single biggest reason to buy is the combination of three 1600mAh lithium-ion batteries and a compact charger that can top up two cells simultaneously from a 5V USB source, which makes it well suited for extended shoots and travel where mains charging is not convenient.

Key Features

• Triple battery pack: Three 1600mAh batteries give multiple full replacements so shooters can swap cells quickly without waiting for one to recharge.
• Dual battery USB charger: The LTD2 charger can charge two batteries at once, reducing downtime when more than one spare is in use.
• Universal USB inputs: Micro-USB and Type-C input options allow the charger to work with common power banks and phone chargers while traveling.
• Smart LED indicators: The intelligent LED display gives a clear visual of charging status and remaining battery capacity so users know when each cell is ready.
• Portable design: The charger is compact and designed for easy carrying, and the Micro USB cable included keeps initial kit weight and bulk low.
• Switchable charging plate: The charger can change plates to accept different battery layouts, adding flexibility for related JVC models.

Who It's For

This kit is aimed at owners of JVC camcorders that use BN-VF707-type cells who shoot events, weddings, travel, or field video where swapping spare batteries keeps work flowing. The package is also a good fit for hobbyists who prefer carrying multiple pre-charged cells rather than relying on a single camera battery and mains charging between sessions.

It is less suitable for users who already have a single long-life professional battery system or those who require extremely fast charging from high-wattage mains-only docks; the LTD2 is built around USB input and moderate 8.4V output rates rather than rapid industrial charging.

Pros & Cons

Pros

• Three 1600mAh lithium-ion batteries provide extended run time and ready spares for uninterrupted shooting.
• Charger supports two batteries at once and has switchable plates, so it handles multiple battery types used in the same camera family.
• Micro-USB and Type-C inputs plus included cable enable charging from power banks or car adapters during travel.

Cons

• The USB-based charger charges at moderate current (800mA per bay) so full recharge cycles can be slower than dedicated high-power chargers.

Our Verdict
