Lithium battery pack is with more than 2000 cycles life,lead acid battery is only with around 500 cycles,you need to buy 3-4 lead acid battery that as long life as lithium battery.
Lead acid battry is much bigger and heavier than lithium battery,lithium battery pack is used in more applications.
Lithium battery pack,why Deligreen?
Lithium battery pack is a system of lithium batteries,containg lithium battery,BMS,outer box.Battery pack is widely used in many applications,such as RV,caravan,solar system,camping,energy storage system,Led street lamp,golf cart,marine,boat,e-car,motorcycle etc.
Battery pack needs to be customized,before placing the order,we need some important parameter.ex.
This is the requirement/customized sheet for you to fill in to get a most precise price.
