1 INTRODUCTION
Deep cycle batteries are a key component in various types of renewable energy systems and the primary
method to store direct current (DC) power produced from sources like solar panels and wind generators. A
battery bank can provide a relatively constant power source when the grid is down or during periods when your
renewable energy system is not producing power and the BattaMax Lithium offers longer life cycles, lighter
weight, higher power, and superior safety over traditional lead acid batteries.
This manual contains vital information regarding proper care and maintenance of your BattaMax Lithium battery.
Read through this User’s Guide carefully and completely BEFORE using and installing your battery.
The manual will provide safety guidelines and procedures for using your battery to ensure optimum performance
and long life. The manual will not provide details about any of the connected equipment to the battery (e.g.:
charge controllers, inverters, etc.). Information concerning any connected equipment should be available from
the equipment manufacturer.

3 INSTALLATION
The BattaMax can be used in any orientation as long as the terminals are accessible and are completely clear of
all objects that could cause short circuiting of the battery terminals.
Important: Batteries deliver large amounts of power that can cause injury and even death. Please observe the
rules set forth in Section 1.1 when working on or around batteries.

Caution: Risk of fire, explosion, or burns. Do not disassemble, heat above 70°C (160°F) or incinerate.
3.1 ENVIRONMENT
Batteries should be installed in a clean, dry area, keeping water, oil, and dirt away from the batteries. The
accumulation of these materials on the batteries can result in self-discharge and possible short-circuits.
If the battery will be used in an enclosure with no air circulation, it is recommended to ventilate the enclosure to
prevent heat buildup.
3.1.1 Temperature
Temperature is a major factor in battery performance and battery life expectancy. The recommended operating
temperature range is between 0oC to 45oC (32oF to 113oF) with a humidity of less than 90%. A minimum
clearance of 0.50” (12.7 mm) between the battery and any other object is recommended to minimize heat
accumulation and avoid heat transfer between batteries.
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.
3.2 CONNECTIONS
WARNING: Faulty connections can lead to poor performance, terminal damage, and possible fire.
Important: Do NOT connect batteries together of different types or vintages.
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.

3.2.2 Threaded Terminals
The BattaMax has two threaded terminals and comes with the necessary bolts and washers to secure a cable
connection.
Place battery connection cable lug (not included) over the threaded insert of the battery terminal ensuring that
the cable lug connection is contacting the metal surface of the terminal. Place the flat washer on top of the cable
lug, followed by the lock washer. Do not place washer between the terminal lead and the battery wire, which
creates high resistance and can cause terminal meltdown.
Add the hexagonal bolt and tighten to a torque of 98-107 (in-lbs), 11-12 (Nm)
