Using the technology of lithium iron phosphate cells this battery has superior safety, lasts for thousands of cycles, and can be run to 100% DOD (Depth of Discharge) under normal conditions.
Has built in automatic protection for over charging, over discharging, high current and high temperature.
Free of maintenance.
Internal cell balancing.
Lighter weight: About 40% - 50% of the weight of a comparable lead acid battery.
Can be charged using most standard lead acid charges (set).
Opperates in wide temperature range: -20℃ to 60℃
Support for Series application expansion (up to 51.2V) and two in parallel.
