NP-F550/F570 4-Pack 2900mAh Batteries with LTD2 USB Charger - Dual

In this review the reviewer looks at a 4-pack battery bundle designed for older camcorders and cameras that take NP-F550/F570 style cells. The bottom line: this kit is for videographers and hobbyists who need long runtime and flexible charging on the go. The combination of four 7.4V 2900mAh lithium-ion batteries and an LTD2 USB charger that can charge two batteries at once delivers reliable extended power for shoots and travel, and the review focuses on real-world battery life and the convenience of the dual USB inputs.

Key Features

• High capacity cells: 2900mAh per battery provides extended runtime so users shoot longer between swaps or recharges.
• Standard voltage: 7.4V lithium-ion chemistry matches the original NP-F550/F570 form factor for broad camera compatibility.
• Dual-bay charging: The LTD2 charger can charge two batteries at the same time, reducing downtime when multiple spares are used.
• Flexible USB input: Micro-USB and Type-C input options with a supplied Micro USB cable let you charge from power banks and USB adapters.
• Intelligent LED display: LED indicators show charging status and give a quick sense of remaining capacity while charging.
• Swapable plates: The charger can change plates to accept different battery styles, adding versatility for users with mixed batteries.

Who It's For

This bundle suits independent filmmakers, event shooters, and casual camcorder owners who keep a set of spares ready. Photographers who use older camera models listed as compatible will appreciate carrying four full batteries rather than hunting for proprietary chargers during a shoot.

Those who need the absolute fastest charger or who require manufacturer-backed warranty support may prefer an original-brand fast charger. Also, users who do not own NP-F550/F570 style batteries should look for a package that matches their specific battery family.

Pros & Cons

Pros

• High 2900mAh capacity gives noticeably longer run time compared with many low-capacity replacements.
• Charger charges two batteries simultaneously, saving time between shoots.
• USB input options and a supplied Micro USB cable make field charging from common power sources easy.

Cons

• Charge rate is modest at 800mA per bay, so full recharge can take several hours compared with fast chargers.
• The kit does not include a Type-C cable despite supporting Type-C input, so users may need to supply one for that option.
