4. Warnings & Precautions
Lithium Iron Phosphate (LiFePO4) batteries are an inherently safe chemistry.
However, safety measures should always be taken. Adhere to the instructions within
this User Manual for safe handling and operation.
Warnings:
Do not charge with a charge voltage above 58.8V.
Do not charge nor discharge battery when ambient temperature is above 55 °C
(131 °F).
Do not install battery where it may contact conductive materials, water, seawater,
strong oxidizers, nor strong acids.
Do not install battery in a location exposed to direct sun, hot surfaces, nor hot
locations. Do not install batteries in a tight clearance compartment, overheating
may result.
Keep any flammable/combustible material (e.g. paper, cloth, plastic, etc.) that may
be ignited by heat, sparks, flames, or any other heat source at a minimum distance
of two feet away from the batteries.
Disconnect batteries immediately if, during operation or charging, they emit an
unusual smell, develop heat, or behave abnormally.
Have a Class ABC or Class BC fire extinguisher on the premises.
Precautions:
Handle batteries and/or battery-powered devices cautiously to not damage
the battery casing or connections.
Do not charge battery if ambient temperature is below 0°C (32 °F), nor
discharge battery if ambient temperature is below -30 °C (-22 °F).
Before storing battery for more than 6 months, charge the battery to 53V or
above.
For long-term storage, disconnect batteries from your power system.
Always wear protective gear when handling batteries.
Do not place any objects on top of batteries.
Make sure all cable connections are properly tightened.
Install and remove batteries using the handles provided.

5. Parts & Components
WARNING: Before installing, make sure to review all warnings and
precautions in Section 4, as well as the installation safety guidelines in
Section 5.1 below.
5.1 Installation Safety Guidelines
●Inspect batteries upon receipt for any signs of damage before use.
●Check to ensure that all cables are in good condition.
●Use a screwdriver with a rubber coated handle.
●When your battery has been charging and has come to maximum charge (up to
58.8V max.), your battery may experience a slight voltage drop either immediately or
within the hour after unplugging. This is normal and should be no cause for concern.

5.3 Battery Installation
Tools needed:
- Screwdriver
Step 1:
Determine the best location to
accommodate your battery unit
for operation.
Step 2:
Unscrew thin metal panel on the
backside of your KONG Elite unit,
using a mini screwdriver.
Step 3:
Connect the standardized
connector side of your 175-amp
Ring Terminal connector cable to
the receiving connector located
on the battery unit.
Step 4:
Place the battery in the space
where you will store it and
operate it.
Step 5:
Lock the wheels so they are not
free to move. This will make your
battery unit more stable in place.
Step 6:
Turn the battery on by pressing
the power button located on the
LED screen.
