## Overview

SBLFP50 is a compact deep-cycle power source for portable radio systems, solar installations and other demanding field applications. Its lithium iron phosphate chemistry provides stable 12.8 V power while offering substantially more usable energy than a comparable lead-acid battery.

An integrated battery management system provides fault protection, cell balancing and optimized performance throughout each cycle. The battery also supports series and parallel connections for applications that require increased voltage or capacity.

Use a compatible LiFePO4 charger with a 14.4 V charging profile. Contact Satel USA to confirm charger, cable and enclosure compatibility for your system.

## Highlights

- 640 Wh of deep-cycle LiFePO4 energy in a compact 13 lb case
- Integrated battery management system for fault protection and cell balancing
- Up to 50 A continuous discharge and 100 A peak discharge for ten seconds
- Rated for 2,500 cycles at 100% depth of discharge and up to 7,000 cycles at 50%
- Supports series and parallel connections for expandable battery banks
