DenCo 12V 5.5Ah Flat Pack LiFePO4 Battery

This is a the mainstay DenCo Batt: A 12.8-volt 5.5 amp-hour custom hand-built DenCo 4S Lithium Iron Phosphate battery. The cells were sourced directly from LiFePO4 cell suppliers and tested/verified in-house. This battery uses a DenCo common port 20A BMS (battery management system). The DenCo provides short-circuit protection, overcharge protection, over-discharge protection, over-current protection, and charge passive cell balancing. These cells are capable of 18A continuous discharge, 60A pulse peak discharge, and the BMS is capable of 20A discharge. This is a powerhouse in a little package.

It has passed quality control testing for charge/discharge cut-off and delivers 5.5+ amp-hours in our tests.

This battery has a single Anderson Powerpole 30A connector for output and input (charging). It is a flat battery pack that works best in scenarios where the battery is in a pocket or compartment out of sight. It has no further buttons, ports, or displays that can be accidentally pushed while stowed away.

It is best used with QRP (low watt) radio transmitters, but can go up to 18 amps in current for powering mobile and portable QRO rigs. The battery was designed by DenCo primarily as a companion battery to portable VHF mobile radio deployments, but can be used for all sorts of other devices that need 12-13 volts of consistent reliable power. Recommended consumption rate is around 6 to 12 amps.
