1 Installation
Although our batteries can be installed in an outside battery box, be sure to confirm the battery box has drain holes to
prevent water from filling the box. Unlike lead-acid, our batteries do not exhaust any harmful vapor and may be installed
inside a trailer, motorcoach, truck camper, or boat cabin. Installing the batteries within an insulated or conditioned space
is always recommended, especially if the batteries will ever be used in temperatures below 32°F.
The custom-molded case of our batteries includes rigid internal support structures to hold cells in place in any
orientation. This allows our batteries to be installed in any position, opening up a range of creative mounting solutions
our competitors are unable to accommodate. We recommend using our unique tie-down system with every installation
to eliminate unwanted movement and reduce vibration. Check our website for more information on tie-down solutions
for your Expion360 batteries.
When connecting multiple batteries with the Expion360 Bus Bars or power cables, tighten the M 8 x 1.25 hex bolts to 8
lb-ft (96 lb-in) using an adjustable torque wrench. Make sure all connections are bundled and well organized to prevent
short circuits. Ensure all cables and circuit protection (fuses and/or circuit breakers) are properly sized for the entire
system. See details about circuit protections in Section 5.2: Circuit Protection .
1.1 Battery Bank Configurations
Do not mix batteries of different ages and sizes in one battery bank.
Use the Expion360 Bus Bars or 4/0 AWG cables of the same length when connecting multiple batteries.
Before installing batteries for use in series, all batteries must be parallel connected and charged to 100%.
Parallel Installation:
Connecting multiple batteries in parallel will increase the available energy (watt-hour), charge and discharge rates
(current), and add capacity (amp-hour) to use your battery bank. The voltage is not increased. Up to (4) batteries may be
connected in a single parallel string. To further increase the battery bank’s overall capacity, additional strings may be
connected to a common bus bar with equal-length cables.
Important: Any batteries wired in parallel using cables must be connected by cables of equal length and gauge (AWG).
