Kastar LCD Dual Smart Fast Charger & 2 Batteries for Sony FV100/FH100

In this review the Kastar LCD Dual Smart Fast Charger with two replacement batteries is evaluated for video shooters and photographers who need dependable spare power for Sony NP-FV100 and NP-FH100 series cameras. The bottom line: it is a practical, cost-effective kit that pairs two high-capacity cells with an intelligent dual charger, making it a good choice for users who want longer runtime and straightforward charging management without fuss.

Key Features

• Ultra-high capacity batteries: The included batteries use high quality Japanese cells to deliver longer runtime and avoid memory effect compared with older cell chemistries.
• Dual fast charging: The charger can simultaneously charge two batteries, helping keep multiple spares ready for shoots and reducing downtime between sessions.
• Wide voltage compatibility: The charger accepts batteries from 6.8V to 16.8V and the control MCU automatically identifies voltage to apply the correct charge profile.
• LCD status display: An LCD shows charging status and battery capacity so you can monitor progress without guessing whether a cell is ready.
• CC/CV charging with safety features: The CC/CV algorithm plus pre-charge and 0V activation functions improve efficiency and help extend Li-ion battery life.
• Manufacturer support: The package includes a 30-day money back guarantee and a 3-year manufacturer warranty for added peace of mind.

Who It's For

The Kastar charger and batteries are aimed at independent videographers, event shooters and hobbyists using Sony cameras that accept NP-FV100 or NP-FH100 style packs who need reliable spare power without paying for OEM packs. It suits users who value longer battery life per charge and the convenience of charging two batteries at once.

This kit is less suited for professionals who require the absolute fastest charge times or integrated camera-brand charging solutions for studio workflows; a dedicated OEM fast charger or camera-mounted power option may be preferable in those cases.
