Kastar NP-F960 NP-F970 Battery 2-Pack Replacement - High Capacity

In this review the Kastar NP-F960 / NP-F970 2-pack is evaluated as a practical replacement battery set for a broad range of GVM bi-color and RGB video lights. The bottom line: this pair is for photographers and videographers who need substantially longer run times from their on-camera or panel lights without paying for factory-branded cells. The reviewer found the most compelling reason to buy is the high capacity 8700mAh cells that deliver extended use between charges while including built-in protection circuitry for everyday safety.

Key Features

• High Capacity: The 8700mAh rating provides noticeably longer run time, so lights stay powered through longer shoots without frequent battery swaps.
• Wide Compatibility: Designed to replace NP-F960 and NP-F970 style batteries for many GVM LED panels and on-camera lights, making it a convenient spare for multiple fixtures.
• Safety Protections: Cells meet UL1642 and CE standards and include over-charge, over-discharge, over-voltage, over-current, and over-heating protection to reduce risk in regular use.
• Cost Effective: Buying a 2-pack saves money over repeated purchases of lower quality replacements and reduces downtime on location.
• Stable Voltage: The 7.4V lithium-ion chemistry provides consistent power delivery for LED panels that expect NP-F960/970 style cells.

Who It's For

This replacement pair suits content creators, indie filmmakers, and photographers who already own compatible GVM LED panels such as the GVM-800D series, 480S/520S panels, or on-camera lights that accept NP-F series packs. It works well as a backup or primary set when longer run time and reliable protection circuitry matter.

Those who should look elsewhere include users who require official manufacturer warranties tied to OEM batteries for professional rental houses, or those needing batteries with integrated LCD charge meters or proprietary contacts not present on standard NP-F960/970 replacements.

Pros & Cons

Pros

• High 8700mAh capacity extends shoot durations and reduces swap frequency.
• Built-in safety protections meet common standards for safer everyday use.
• Two-pack provides instant redundancy so you can cycle one while charging the other.

Cons

• Not an OEM branded cell for users who need manufacturer-verified warranty alignment.
