4. BATTERY INSTALLATION
4.1. Battery Connections
To maximize the performance and to ensure safe operation of your battery, use
the appropriate cable size and tighten connections using the proper torque value.
Refer to the data sheet for your particular battery's torque value. It is recommended
to use a washer. Place the washer between the cable lug and nut, not between the
cable lug and battery terminal surface.
4.2. Cable Size
Choose the appropriate cable size
based on the expected load of
your system. See the table below
– ENEC 310.15 (B)(16) – Allowable
Ampacities for copper cables
rated at 167°F (75°C) operating at
an ambient temperature of 86°F
(30°C).
4.3. Torque Values
Terminal connections should
adhere to the appropriate torque
values for the specified terminal
type to provide optimum electrical
conductivity. Refer to the data sheet for your particular battery's torque value. Over-
or under- tightening the connections can result in terminal breakage, over-heating
and/or terminal melting. Use a rubber handled or insulated wrench when making
terminal connections to avoid an external short circuit.
4.4. Terminal Protection
Battery terminals may be covered with a plastic cap to prevent an external short
circuit. Terminals must be covered with a protective cap or non-conductive tape
prior to battery disposal to a lithium recycler.
