Kastar 4-Pack Battery + LTD2 USB Charger Replacement for JVC

In this review the Kastar 4-Pack Battery + LTD2 USB Charger is evaluated for videographers and owners of older JVC GR-D series camcorders who need spare power and flexible charging. The bottom line: this pack is for users who want multiple genuine-looking replacements and a compact dual USB charger that can top up two batteries at once, making it a practical kit for shoots and travel. The review focuses on capacity, charging options and real-world convenience rather than brand hype.

Key Features

• High capacity batteries: The 2400mAh Lithium-Ion cells provide extended runtime so users can record longer without swapping batteries frequently.
• Dual battery charging: The LTD2 charger can charge two batteries at once, cutting downtime between shoots and keeping spares ready.
• Interchangeable plate: The charger accepts a changeable plate so it can accommodate the compatible JVC battery models without forcing awkward fits.
• USB power input: With Micro-USB and Type-C input options and a 5V 2-3A input rating, the charger is convenient to power from power banks and modern adapters.
• LED charging indicators: Intelligent LED display shows charging status and battery capacity so users can see progress at a glance.
• Compact and portable: The lightweight charger and four spare batteries are easy to carry for field work and travel.

Who It's For

This kit is aimed at owners of JVC GR-D camcorders that use the BN-VF707, BN-VF714 and BN-VF733 family of batteries who need multiple spares for extended shoots or backup power. It fits small video crews, hobbyists, and anyone who prefers to carry several precharged batteries rather than relying on a single cell during an event.

It is less suitable for users who need manufacturer-branded cells for warranty reasons or who require very fast professional chargers with higher amperage than the LTD2 provides. Also, those who do not own compatible JVC models should verify fit before buying.

Pros & Cons

Pros

• Four 2400mAh Lithium-Ion batteries supply long runtime so fewer swaps are needed on location.
• Charger supports charging two batteries simultaneously, saving time between sessions.
• Micro-USB and Type-C input options plus a supplied Micro USB cable make it easy to power from modern chargers and power banks.
• LED indicators communicate charging progress and remaining capacity clearly.

Cons

• The charger output is limited to 800mA per slot, which is adequate but not as fast as some high-current professional chargers.
• No dedicated case is included, so buyers may want a small pouch to protect spare batteries in transit.
