Golf Cart Upgrade, Lead to Lithium Battery, EG4

Let’s put a new waterproof lithium battery in this old Golf Cart.
This is a 2003 Club Car Golf Cart that came with a 48V lead acid battery. We are swapping out the old lead acid batteries for a new 48V (51.2V) Lithium. The battery is a 100 Ah, 5.12kWh, LiFePO4, sold by Signature Solar under the brand EG4. The type we are using is waterproof.
