It is important to note that the temperature of the battery and the ambient temperature can differ significantly. As
an ambient temperature can be changed rapidly, the battery temperature is slower to change due to the thermal
mass of the battery. Batteries that are exposed to colder climates should be kept at a higher State of Charge
(SOC) to prevent freezing. A frozen battery must be completely thawed prior to any use.

ONNECTIONS
WARNING:
Faulty connections can lead to poor performance, terminal damage, and possible fire.
Battery cables provide the link between the batteries, equipment, and charging system. The battery cable
should be sized for the maximum load of the system where the voltage drop on the cable will not exceed 0.2
volts. To ensure proper connections, please use the wire gauge reference in Sec 3.2.1. Please note: UL and
NEC electrical cable amperage ratings are lower than the chart below.

Terminals
The BattaMax comes with two terminal options, a standard 5/16” course thread or SAE Automotive post as
shown below.
Select the appropriate terminal for the battery cable you will be using.
3.2.2.1
SAE AP (Automotive Post)
Screw the AP post adapter onto the 5/16” threaded stud and torque to 85-95 (in-lbs), 10-11 (Nm).
Fit the AP Clamp connector (not included) onto the adapter and torque to 50-70 (in-lbs), 6-8 (Nm).
