2-Pack Upgrade 7000mAh Rechargeable Batteries for Trail Camera

In this review the DMMNS 2-Pack Upgrade 7000mAh Rechargeable Batteries are evaluated for owners of SPYPOINT Flex series and similar cellular trail cameras. The bottom line: these replacement LIT-22 PRO packs are for users who want significantly longer runtime and fewer maintenance visits, because the upgraded 7000mAh capacity and USB-C charging reduce downtime compared with standard alkaline sets. The reviewer found them most useful when cameras are deployed for weeks at a time and appreciated the convenience of built-in charging and broad temperature tolerance.

Key Features

• 7000mAh capacity: Provides extended runtime to cut the frequency of battery changes and reduce camera downtime on long deployments.
• Wide compatibility: Works as a direct replacement for LIT-22 style batteries in Flex-M, Flex-G-36, Flex-PLUS, FLEX-S and Flex-Dark models, simplifying inventory for users with multiple cameras.
• Rechargeable longevity: Rated for more than 800 charge cycles, which lowers long-term operating cost compared with disposable batteries.
• USB-C charging: Built-in USB-C port makes topping up packs straightforward and the charging indicator shows when the pack is fully charged.
• Temperature adaptability: Designed to function in a wide temperature range so cameras remain powered in varied field conditions.

Who It's For

This battery pack is best for hunters, wildlife managers, and property owners who place cellular trail cameras in the field for multiple weeks and want to reduce time spent swapping disposable batteries. The high capacity and USB-C rechargeability make it suited to users who can return to a camera occasionally to recharge rather than replace many alkalines.

Those who should look elsewhere include users who need a single-use disposable solution or those whose cameras require a different physical battery form factor. Also, anyone who only ever runs cameras for very short bursts may not benefit from the larger capacity.

Pros & Cons

Pros

• Longer runtime from the 7000mAh capacity reduces maintenance trips to field cameras.
• Built-in USB-C port and charging indicator make recharging convenient and clear.
• Good value over time thanks to up to 800+ charge cycles compared with single-use batteries.
• Compatible with a broad range of Flex series cameras, easing replacements across a fleet.

Cons

• Some customers report mixed charge-retention behavior, so a small number of packs may not hold charge reliably.
• Using a low-output 5V2A charger may lengthen charge times or prevent a full charge; a 5V3A or higher charger is recommended.
