Kastar 2-Pack BP-U98 Battery Replacement for Sony Cameras - Long Run

In this review the Kastar 2-Pack BP-U98 battery replacement is evaluated for videographers who need reliable extended runtime when using Sony XDCAM and PMW camcorders. The bottom line: this pair delivers higher capacity and USB power-bank versatility so shooters get longer continuous recording and a convenient USB output for charging accessories. The review focuses on real-world runtime, safety features, and compatibility with a long list of Sony BP-U series models to help camera operators decide if it is a practical, cost-conscious swap for their original batteries.

Key Features

• High capacity: Each 14.4V, 7200mAh battery provides noticeably longer run-time than many original BP-U packs, which reduces mid-shoot battery swaps.
• Broad compatibility: Designed as a replacement for numerous Sony BP-U models and works with many PXW and PMW camcorders listed by the manufacturer.
• USB output: The built-in USB port lets the battery act as a power bank to top up smartphones and small USB devices on location.
• Safety protections: Internal circuits protect against over-charge, over-discharge, over-current, over-voltage, and over-heating for safer daily use.
• Charger compatibility: Works with common Sony BC-U1 and BC-U2 style chargers for straightforward recharging on set.

Who It's For

The Kastar 2-Pack is aimed at event shooters, ENG crews, and independent videographers who run longer shoots and need dependable battery life without carrying multiple smaller packs. It is useful for anyone who values the convenience of a USB output to keep phones or small accessories powered while working on location.

Those who should look elsewhere include operators who require manufacturer-certified batteries for warranty or service reasons, or users who need integrated camera telemetry that some OEM batteries provide. If weight and the absolute smallest form factor are critical, a lower-capacity OEM pack may be preferable.

Pros & Cons

Pros

• High 7200mAh capacity yields longer run time and fewer swaps between takes.
• USB output port doubles as a power bank for phones and accessories.
• Built-in safety circuits meet common CE standards, reducing risk of failure during use.
• Good value for a two-pack, lowering replacement cost compared with buying singles separately.

Cons

• It is a third-party replacement, so users who require OEM certification for studio support may prefer original-brand batteries.
• The batteries add some extra weight compared with lower-capacity cells, which can matter for handheld or gimbal setups.
