Kastar CGA-D54 4-Pack Battery and LTD2 USB Charger - High Capacity

In this review the Kastar 4-Pack CGA-D54 replacement battery kit is assessed for videographers and power users who need long runtime and flexible charging options. The bottom line: this kit is for anyone using older Panasonic camcorders who needs reliable spares and a compact dual USB charger; the single biggest reason to buy is the combination of high 6600mAh lithium-ion capacity per cell and the ability to charge two batteries at once from USB power. It is practical, portable and designed to replace the common CGA-D54 family of cells.

Key Features

• High Capacity: Each battery offers 6600mAh at 7.4V for extended recording time compared with typical stock cells, reducing downtime between shoots.
• Dual Charging: The LTD2 USB charger can charge two batteries at the same time so you can keep a pair ready without needing separate chargers.
• Interchangeable Plate: The charger plate can be swapped to accept different battery plate types, which adds compatibility and convenience for mixed workflows.
• Multiple Input Options: The charger accepts both Micro-USB and Type-C input and includes a Micro USB cable, so it can be powered from power banks or common USB chargers.
• Intelligent LED Display: LED indicators show charging status and battery capacity, helping you manage power and know when a pack is ready.
• Low-power USB Input: The charger runs from 5V 2-3A input and provides 8.4V 800mA outputs, allowing field charging from many portable power sources.

Who It's For

This kit is aimed at camera operators, event videographers and owners of Panasonic camcorders that use the CGA-D54 family of batteries who need multiple spares and a charger that works from USB power. The extra capacity and dual charging make it a good match for shoots where mains power is not guaranteed.

It is less relevant for users who already have a high-performance dedicated AC charger or for those whose camera uses a different battery family; also users requiring manufacturer service or original-brand batteries for warranty reasons should look elsewhere.

Pros & Cons

Pros

• High 6600mAh capacity provides noticeably longer runtime between swaps.
• Dual-bay LTD2 charger charges two batteries simultaneously from USB, saving time.
• Interchangeable plate and dual input (Micro-USB and Type-C) add flexibility for travel and mixed equipment setups.
• LED indicators give a clear view of charge progress and remaining capacity.

Cons

• The charger output is 8.4V at 800mA per bay, so charging is not as fast as some high-current dedicated AC chargers.
• This is a third-party replacement; users preferring original-brand packs for manufacturer support should consider brand-name options.
