Big Battery 36V 4X GATOR MAX KIT – LiFePO4 – 480Ah – 20kWh - K0593
MAX OUT YOUR MACHINE! BigBattery’s 36V 20 kWh Forklift Kit is the ultimate all-in-one solution for your forklifts and other industrial machines, guaranteed to operate 200% longer than any other lead acid alternative, with ZERO decline in performance as the batteries discharge.
Unlike lead acid or gas-powered options, our Forklift Kit requires ZERO maintenance, emits ZERO toxic fumes or other harmful substances, allows for opportunity charging during breaks, and has a lifespan of up to 10 years, compared to lead acid batteries that need to be replaced every 2 -3 years, and propane that needs to be replaced regularly. With brand
new LFP cells, an advanced BMS in each unit, and extensive safety features, you can rest assured that this Forklift Kit will provide safe, reliable power for your industrial applications for years to come. Upgrade today!
“Forklift Counterweights” are NOT included in this kit and are required for this installation. Our batteries are newer, stronger and lighter than lead acid. You must add a counterweight to the back of your forklift to retain payload balancing per your maximum carrying capacities.
