Kastar 2-Pack BP-U98 Replacement Battery for Sony Camcorders - Long

In this review the Kastar 2-Pack BP-U98 replacement battery is assessed for videographers and camera operators who need reliable extended power for compatible Sony camcorders. The main reason to consider this pack is straightforward: it replaces common Sony BP-U series batteries while offering a higher capacity and a USB output so each cell can double as a power bank. For editors, ENG shooters or anyone on long shoots who needs extra runtime and USB charging flexibility, this kit aims to reduce battery swaps and keep accessories powered without carrying separate power banks.

Key Features

• High capacity: The 14.4V, 7200mAh rating provides longer run time than many original batteries, so cameras run longer between swaps.
• USB power bank: The built-in USB output lets you charge a smartphone or other USB device directly from the battery, adding utility on location.
• Compatibility: Works as a replacement for a wide list of Sony BP-U series batteries and is compatible with BC-U1 and BC-U2 chargers for convenient charging options.
• Safety protections: Integrated protection circuitry guards against over-charge, over-discharge, over-voltage, over-current and overheating for safer field use.
• Cost effective two-pack: Shipping two batteries together gives extra runtime and reduces the frequency of buying single expensive OEM cells.

Who It's For

This 2-pack is aimed at professionals and advanced amateurs who use Sony PXW and PMW series camcorders and need extended on-camera runtime without frequent battery swaps. The USB output is useful for run-and-gun shooters who also need to keep phones, LED lights or small accessories charged on set.

People who should look elsewhere include users who require manufacturer warranty-backed OEM cells for rental houses with strict policies, or those who only need a single spare battery and do not need the power-bank feature.

Pros & Cons

Pros

• Higher capacity than many originals, providing noticeably longer recording sessions per charge.
• USB output adds versatility by powering phones and accessories without a separate power bank.
• Built-in safety circuitry and compliance with common safety standards improves peace of mind on set.
• Two-battery pack reduces downtime and is more economical than buying singles.

Cons

• Not OEM-branded, so some rental houses or workflows that require factory batteries may not accept it.
• The increased capacity adds some weight compared with lower-capacity replacements.
