Lithos Low Voltage Packs
Lithos Low Voltage battery packs are high-density general purpose batteries that meet the needs of a broad set of applications, including mobile robotics and specialty vehicles. These low voltage systems feature passive cooling and are easy to integrate into existing applications.
Lithos Energy Low Voltage battery packs are fully-integrated, 18650-based battery packs that offer excellent performance in a compact design. The low voltage packs can be ordered as either a 2.1 kWh NCA pack for high energy density or as a 700 Wh LFP pack for high power density in order to serve a wide variety of applications.
This pack features a light-weight polymer enclosure that is factory sealed and IP67 rated. These batteries may be configured for connection in parallel up to 12 units to meet a variety of application needs.
Each unit includes an integrated Battery Management System (BMS) that monitors the operation and health of the battery pack. The BMS calculates the State of Charge (SOC) and State of Health (SOH) and broadcasts these values in real time over a CAN 2.0B network. The BMS also handles cell balancing and provides protection from over/under voltage, temperature and excessive current draw. Each pack also includes an internal fuse, current sensor, contactor (on +) and pre-charge cicuit.
All Lithos Energy packs are designed, assembled and tested in our manufacturing facility in California.
