Ark Battery, 100AH, 51V (48V nominal) 5.12kwh lithium iron phosphate battery with terminals on front and back, Impactiv balancing system, LCD, handles on front and side. Supports vertical installation or horizontal using the Ark flex racking system.
FLEX RACKING
ARK Battery Flex Racking is laser-formed from 3/16 and 1/4” steel and supports battery stacks up to seven high.
MODULAR DESIGN!
Modular design! Flex racking supports adding additional ARK Batteries to your bank down the road. The assembly hardware is included with each battery.
Every ARK Battery is equipped with a special balancing system to ensure that all cells are charged and discharged equally. This serves the same purpose as ‘equalizing’ does for a lead-acid battery. While LiFePO4 batteries may not be equalized externally, it is critical that all cells within maintain the same voltage. An ‘imbalanced’ battery will result in nuisance BMS shut-offs, lower capacity and a drastically reduced cycle life.
Most batteries in today’s market come with a small balancing system known as passive balancing. In passive balancing, a set of resistors begin to dissipate (burn off) power from any cell that has an individual voltage higher than 3.6V. This dissipation typically occurs at 50-100 ma (5% to 10% of 1 amp). We have found this balancing method to be ineffective to meet the stringent requirements of cell balancing. In short, it is too slow as well as inefficient.
IMPACTIV balancing, used in all ARK Batteries channels extra power from high-volt cells to low-volt cells, and deploys additional dissipative consumption should a cell reach critically high voltage.
