Product Description

The M12 series are lithium iron phosphate batteries with high continuous discharge current and one of the most feature rich lithium modules available on the market.

The M12-400 supports a high continuous discharge current of 300A which makes it perfect to handle heavy duty appliances like air-compressors or coffee machines.

Using LiFePO4 cells, each module provides 5120 Watt Hour (WH) of energy with capability to parallel up to 8 units – delivering a Monumental total of 40,9600 wh of energy storage if required. Each module weighs just under 42KG which makes them far lighter than a conventional AGM battery bank.

200A (0.5C) charging and 0.75C discharging capability even under parallel configuration ensures the lithium modules can be fast charged and provide high discharge current to the inverter. Meaning with just 1 module you can discharge at 300A, and with 8 connected in parallel 2400A!. The integrated shunt provides real time state of charge (SOC). As an example the Kinergier Mobile CM3.0L with integrated 180A charger can fully charge 4 modules (5120Wh) in a 150 minutes.

CAN connection between each lithium module ensures safe, efficient and intelligent monitoring so maximising charge rates and life cycle – this allows 100% depth of discharge (DOD) without compromising battery and system life.
