DKW SERIES WALL MOUNTED LITHIUM BATTERY
Features
● Long Cycle Life: 10 times longer cycle life time than lead acid battery.
● Higher Energy density: the energy density of lithium battery pack is 110wh-150wh/kg,and the lead acid is 40wh-70wh/kg,so the weight of lithium battery is only 1/2-1/3 of lead acid battery if the same energy.
● Higher Power Rate: 0.5c-1c continues discharge rate and 2c-5c peak discharge rate ,give much more powerful output current.
● Wider Temperature Range: -20℃~60℃
● Superior Safety: Use more safer lifepo4 cells,and higher quality BMS,make full protection of the battery pack.
