Wiring Guide
The illustrations below show how to properly wire lithium batteries.
Minimum 1in gap inbetween batteries and
between batteries and battery enclosure walls
All battery interconnects to
be equal length and gauge
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.
Connect negative terminals together
Connect positive terminals together
All battery to busbar
connections to be equal
length and gauge
Ex) Inverter
Ex) Converter
Ex) Solar Controller
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).
Positive busbar
Negative busbar
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).
Split lock washer

Do NOT stack smaller
terminals under large ones
Battery Bank Terminal Connections
Ensure correct strip length and that
stripped wires are completely inserted
into terminal before crimping
Minimum 1in gap inbetween batteries
Torque battery terminals to
11-14.7 N*m ( 97.3-130 in*lbs)
Terminals with open-end crimp
barrels may be used to verify wires
are fully inserted before crimping
