Important information regarding possible personal injury.
▲ CAUTION
Important information regarding possible equipment damage.
Additional information concerning important
procedures and features of the battery.
1.2 General Warning
▲ CAUTION
It is important to operate the device with care
to avoid undesirable consequences.
Do not throw in the garbage. Do not dispose in re.
Use personal protective equipment when working with batteries.
▲ NOTE
Additional information concerning important procedures and features of the battery. Read all the instructions before
installation, operation and maintenance.
This product must be recycled and is made of recycled products.
▲ CAUTION
Do not disassemble or modify the battery. If the battery housing
is damaged, do not touch exposed contents.
1.3 Fire Risk
▲ WARNING
Risk of re - No user serviceable parts.
• Battery has a Battery Management System (BMS) with integrated solid state relay to reduce re risk.
• Primary suppression for lithium battery res is water, the secondary suppression is CO2 powder and halon.
1.4 Electric Shock Risk
▲ WARNING
For wet and electrically uninsulated working conditions, electric
shock risk is high, and can cause injury and death.

mishandled or abused.
1.8 DC Motor Connection
Direct connection to DC motors, without proper safety protection including motor controllers, and external motor voltage clamping
systems (such as high power anti-parallel diodes or braking resistor systems), may result in damage to the internal battery
pack protection system which may result in unsafe situations. Please consult Discover Battery technical support before directly
connecting any motor loads.
1.9 Transportation
If the battery is not installed in equipment, it must be transported in the original package or equivalent.
Batteries are tested according to UN Handbook of Tests and Criteria, part III, sub section 38.3 (ST/SG/AC. 10/11/Rev.5). For
transport the batteries belong to category UN3480, Class 9, Packaging Group II.
2. Battery Operating Limits
2.1 Maximum Battery Operating Limits
The battery should not be operated outside the Maximum Operating Limits, the BMS will open its internal relay and disconnect
the battery if any of the following limits are exceeded.

▲ NOTE!
Intentional bypassing of BMS to operate the battery
outside maximum and minimum limits voids warranty.
2.2 Recommended Battery Operating Limits
Although the battery is capable of performing up to the Maximum Battery Operating Limits noted, the following settings are
recommended to maximize battery health and account for unforeseen external conditions.
