About the aentron Lithium-ion Battery
Using the Lithium-ion Battery
Page 8/53 Lithium-ion Battery aentron GmbH
Version 1.3
2. About the aentron Lithium-ion Battery
2.1. Using the Lithium-ion Battery
The aentron lithium-ion battery has been designed so that it can be used as
a modular assembly, either as a single device or in a parallel configuration
with other appropriate lithium-ion batteries of the same capacity and power
of up to 60 V.
The modular concept of the lithium-ion batteries enables scalable
configurations of up to a maximum of 4 modules in parallel of up to 60 Vdc,
without a higher-level control system being required. The lithium-ion
batteries in conjunction with our integrated Battery Management
System (BMS) are therefore designed and configured for high performance
and safe operation.
All lithium-ion batteries have galvanic isolation to ground > 1,000 Vdc.
Thanks to the integrated BMS, all safety-related parameters of the lithium-
ion battery - such as over / undervoltage, over-current, over / under
temperature, cable breaks and charge level - are continuously monitored.
2.2. Intended Use
The lithium-ion battery is equipped with the latest Li-NMC cell technology
and is designed for the following applications:
■ E-Industry
■ E-Maritime
■ E-Mobility
■ ON / OFF grid
The lithium-ion battery can be operated as a stand-alone solution or used in
a parallel connection with a maximum of 4 x lithium-ion batteries. Should you
require greater capacities, please contact your authorised aentron dealer.
The limits to use described in this user manual must always be complied
with.
The lithium-ion battery must only be used for purposes described in this user
manual.
2.3. Foreseeable Misuse
Use of the lithium-ion battery other than or in addition to that described in
chapter 2.2. Intended Use is considered to be improper use, meaning
incorrect use, and this leads to warranty invalidation.
This applies in particular to the use of the lithium-ion battery for applications
in medical or aerospace industries.

You can find a detailed explanation of the safety and warning symbols in
chapter 1.3. Explanation of Symbols.
Special safety regulations may apply to particular activities. Safety and
warning signs for such activities can be found in the respective chapters of
this operating manual.
3.1. Basic Functional Safety
For the operation of the lithium-ion battery, safety, accident prevention and
environmental protection regulations must also be followed.
Only use the lithium-ion battery:
■ For its intended purpose, in a safe and hazard-conscious manner and by
paying attention to this operating manual.
■ If all safety equipment is present and fully functional.
■ If the lithium-ion battery is in a technically flawless condition.
This also includes:
■ The warning signs and labels attached on the lithium-ion battery must
always be complete and in a legible condition. Replace damaged or
illegible signs. Please refer to your authorised aentron dealer.
■ Only perform installation, cleaning and / or disassembly work when the
lithium-ion battery is switched off.
NOTICE
Physical damage to the lithium-ion battery due to excessive current
flow through voltage compensation.
 Prior to connecting in parallel, measure the respective voltage of the
individual lithium-ion batteries.
Make sure that the voltages between the individual lithium-ion
batteries DO NOT deviate > 1 Vdc.
3.2. Warnings of a General Nature
■ ONLY take the lithium-ion battery out of the original packaging if it is
required for use.
■ DO NOT subject the lithium-ion battery to any excessive mechanical
shocks; e. g. from dropping.
■ DO NOT remove the attached handles which are required for preventing
accidental drop damage.

Safety
Thermal Hazards
Page 14/53 Lithium-ion Battery aentron GmbH
Version 1.3
■ The pressure-equalisation membrane must NOT be blocked or covered.
The lithium-ion battery does not need any extra ventilation under normal
operating conditions.
■ In addition, you should fit your application with an electric fuse which is
rated lower than the fuse of the lithium-ion battery (e. g. 10 % to 20 %
lower). Please note the technical data of the lithium-ion battery in this
regard.
Type M fuse: 63 A
■ If the internal fuse of the lithium-ion battery fails, please refer to your
authorised aentron dealer for support and repairs.
DO NOT attempt to replace the fuse, otherwise the warranty for the
lithium-ion battery will be invalidated.
■ ONLY use chargers which have been authorised by aentron GmbH.
■ Ensure correct polarity when connecting the lithium-ion battery and the
charger.
■ DO NOT combine or mix different manufacturers, capacities, sizes or
types of other battery technologies with the lithium-ion battery.
■ ONLY use the lithium-ion battery for the intended application and power;
see chapters 2.2. Intended Use and 2.4. Technical Data.
■ Ensure that the voltages between the individual lithium-ion batteries
DO NOT deviate > 1 Vdc for every parallel connection.
■ The lithium-ion battery boasts IP protection class 66, and is thus splash-
proof. It should, however, not be subjected to wet conditions
continuously for its own protection.
■ Switch the lithium-ion battery off when not in use.
■ Store away the original packaging for servicing / repairs / disposal at the
end of the service life.
3.3. Thermal Hazards
