SZ300 - Uses specialised electrolyte formulas to enable ion movement in extreme cold, preventing lithium plating found in standard LiFePO4 cells. Paired with a smart BMS these batteries ensure safe, reliable operation in harsh conditions.

High Capacity - SZ300 offers 3840Wh of high-capacity power, ideal for demanding applications and long use.

Grade A Cells - Beyond Batteries uses only Grade A cells for reliable, long-lasting performance.

BMS - Our high-integrity Battery Management System (BMS) ensures safe, reliable performance, with low temperature protection to keep cells safe in cold conditions.

Ultra Low Temperatures - Charge from -20℃ & discharge as low as -30℃ without the need for battery heaters.

Safety First - LiFePO4 - the proven, safe lithium option. Protected by an advanced BMS for maximum longevity.

Charge & Discharge - 2 hour fast charge, 250A continuous output, and 500A peak for high-use power start-ups.

Long Cycle Life - Provides 3000 cycles at 80% depth of discharge.

Size & Weight - Compact battery, 38kgs, Ideal for large security towers, traffic signals & VMS. For use with inverters for AC power.

Dimensions - L:525mm W:242mm H:224mm (widest parts of casing)
