Designed for Outdoors

High-strength fiber composite polypropylene with rib reinforcements for enhanced durability and rigidity

High-density EVA foam protects the lithium cells and electronics against shock and vibration

Multiple temperature sensors enhance safety and protect the battery through constant monitoring of the inner cell temperatures, automatically switching the battery off if high or low temperature thresholds are exceeded

Passive charge level equalization between the cells promotes even consumption and rebalancing which leads to optimal performance and preserves a long battery life

High-density EVA foam protects the lithium cells and electronics against shock and vibration

The internal pressure relief valve provides additional safety

Permanently elastic, proven Sikaflex® 291i sealant for additional sealing of all openings in the housing

IP67 waterproof and dustproof switches and connectors
