WIRING GUIDE
The illustrations below show how to properly wire lithium batteries.
Batteries should be installed upright for mobile applications.
BATTERY BANK TERMINAL CONNECTIONS
All battery interconnects, busbar, and device connections to resist vibration by using nylon insert lock nuts, thread locking fluid, or lock washers (split lock or external tooth).
250AH LITHIUM BATTERY BANK PARALLEL CONNECTION
Note: Up to a maximum of 4x 250Ah lithium batteries may be connected in parallel. Lithium batteries may not be connected in series. New batteries should never be connected to old batteries. All batteries should be charged to a minimum of 13V before connecting them together.
All busbar connections to external devices (inverter, converter, solar controller, etc.) to be equal length and gauge, sized appropriately for each device with suitable positive circuit protection (fusing or breakers).
