Quick Start Guide (GP-LIFEPO4-100-12V)

Wiring Guide
The illustrations below show how to properly wire lithium batteries.
Batteries should be installed upright for mobile applications.
100Ah Lithium Battery Bank Parallel Connection
Note: Up to a maximum 4x 100Ah 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 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).

Ensure correct strip length and that
stripped wires are completely inserted
into terminal before crimping
Positive busbar
Torque battery terminals to
11-14.7 N*m ( 97.3-130 in*lbs)
Minimum 1in gap inbetween batteries and
between batteries and battery enclosure walls
Connect positive terminals 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).
