Kastar 4-Pack Battery and LTD2 USB Charger Replacement - Dual Charge

In this review the Kastar 4-Pack Battery and LTD2 USB Charger replacement is assessed for camcorder users who need reliable spare power. The package aims mainly at owners of older JVC GR-D series camcorders and offers a clear reason to buy: a high-capacity 2400mAh Lithium-Ion battery plus a flexible dual USB charger that can handle two batteries at once. For anyone who shoots long events or travels with limited access to mains power, this kit replaces aging packs and adds an intelligent charger with both Micro-USB and Type-C inputs.

Key Features

• 2400mAh Capacity: The high capacity battery extends run times significantly compared with typical older factory packs, reducing downtime between charges.
• Dual Charging: The LTD2 charger can charge two batteries simultaneously, useful for users who keep a spare ready during shoots.
• Changeable Plate: Interchangeable charging plates let the charger accept different battery shapes for broader compatibility within the supported JVC models.
• Multiple Inputs: Micro-USB and Type-C inputs plus a included Micro-USB cable provide flexible charging from power banks, wall adapters, or laptop USB ports.
• Intelligent LED Display: Built-in LED indicators show charging status and give a quick visual sense of battery capacity while charging.
• Portable Design: The charger is compact and light, making it easy to carry as part of a camera kit for location shooting or travel.

Who It's For

This kit is designed for owners of JVC GR-D series camcorders who need direct replacements for BN-VF707, BN-VF714 and BN-VF733 battery models and who value longer run times and faster turnaround between takes. It suits videographers who travel, cover events, or work on location and prefer carrying multiple ready batteries rather than relying on a single pack.

It is not aimed at users whose camcorders require different battery families or who need a manufacturer-branded OEM charger for warranty reasons; those users should verify model compatibility carefully before purchasing.

Pros & Cons

Pros

• High 2400mAh Lithium-Ion cells provide noticeably longer runtime than many older stock batteries.
• Charger can handle two batteries at once, speeding workflow between shoots.
• Flexible Micro-USB and Type-C inputs mean you can charge from modern power sources and include a cable in the box.
• LED indicators make it easy to see charge progress without guessing.

Cons

• Compatibility is limited to specific JVC battery and GR-D camcorder models, so it is not universal.
• The charger output is modest (8.4V, 800mA per slot), so charging two batteries simultaneously takes longer than a high-current single-bay fast charger.
