Kastar 4-Pack Ni-MH 6.0V Camcorder Batteries + Smart USB Charger

In this review the focus is on practical power for older JVC camcorders and compatible devices. The Kastar 4-Pack includes four Ni-MH 6.0V 2650mAh batteries and a compact smart USB charger, and the single biggest reason to buy is simple: it replaces multiple proprietary batteries and adds a convenient USB-charge option so users can keep shooting without hunting for rare packs. The reviewer found the kit especially useful for travel and extended recording sessions where carrying extra cells and a single USB charger beat bulky dedicated chargers.

Key Features

• Battery Type: Uses Ni-MH chemistry which offers dependable, rechargeable capacity suited to repeated camcorder use.
• Capacity: Each battery supplies 2650mAh which provides longer runtime than many stock replacements in the same voltage class.
• Smart USB Charger: The included charger has an intelligent LED display that shows charging status and estimated battery capacity for easier monitoring.
• Multiple Inputs: Charger accepts Micro-USB and Type-C input and ships with a Micro USB cable, so it works with common power banks and phone chargers.
• Portable Kit: The set of four batteries plus one compact USB charger makes it straightforward to carry spares for trips without extra bulky gear.
• Charger Output: Charger output is 6.0V at 800mA, a balance between safe charge rate and reasonable recharge time for Ni-MH cells.

Who It's For

This kit is aimed at camera owners using JVC models that accept BN-V11U, BN-V12U, BN-V14U, BN-V18U, BN-V20U, BN-V22U, BN-V24U or BN-V25U style batteries, and for hobbyists who prefer carrying multiple spare batteries rather than swapping to a single high-capacity unit. It suits travelers and event shooters who need reliable runtime and the flexibility to charge from USB power sources.

Users who should look elsewhere include those who require fast professional charging bays with higher amperage per channel or those who need batteries with different voltages or chemistries. Also, if proprietary fast-chargers and manufacturer service are essential, an OEM solution may be preferable.

Pros & Cons

Pros

• Four replacement Ni-MH batteries provide ample spare capacity for extended recording sessions.
• Smart USB charger with LED status makes it easy to see charging progress and approximate capacity at a glance.
• Multiple charging inputs (Micro-USB and Type-C) increase compatibility with modern power sources and power banks.

Cons

• Charger output is limited to 800mA which means charging each cell is not the fastest option for users who need very quick top-ups.
