Sizing Cables
Battery cables (sold separately) should be appropriately sized to handle the expected load.
Please refer to the following table for the ampacities of copper cables with different gauge
sizes.

The above values are from the NEC Table 310.15(B)16 for copper cables rated at 75°C
(167°F), operating at an ambient temperature of no more than 30°C (86°F). Lengths in excess
of 6 feet (1829 mm) may require heavier gauge cable to avoid excess voltage drop in under
-
sized wiring.
Connecting Batteries in Bank
●
DO NOT connect batteries in series. Doing so can cause catastrophic failure.
●
DO NOT connect batteries with different chemistries, rated capacities, nominal voltages,
brands, or models in parallel.
●
Please avoid excessive voltage difference between parallel connected batteries to avoid
triggering the over-current protection.
●
The cables between each parallel connected battery should be of equal length
to ensure
that all batteries can work equally together.
●
DO NOT connect more than 8 batteries in parallel.
