Series & Parallel Configuration
During the wiring of sequenced batteries, it is imperative to adhere to the following guidelines to ensure optimal
safety and performance:
• Avoid Connecting to a Single Battery: Do not connect both negative and positive wires from your electrical
system to a single battery. Also, avoid connecting them to batteries located in the middle of the sequence.
• Wiring Multiple Batteries in Parallel: When connecting several batteries in parallel, it is important to ensure
that the negative and positive wires from your electrical system are attached to the battery bank correctly.
The first battery in the sequence should have its negative terminal connected to the negative wire of your
system, and the last battery in the sequence should have its positive terminal connected to the positive wire
of your system. Please note that these batteries cannot be connected in series.
Wiring Considerations
Our system supports expansion with up to 10 batteries connected in parallel, achieving a robust 48V 1000Ah setup.
10 In Parallel - 48V 1000Ah
EP48100 batteries cannot be used in series.
6. Regular Maintenance: Annually, the batteries should be individually charged after being detached from
the series. Upon reassembly, the voltage difference should not exceed 0.5V.
Compliance with these precautions ensures reliability and longevity for this LiFePO4 battery system.
Warnings
1. Do not immerse the battery in water or allow it to get wet.
2. Do not use or store the battery near sources of heat such as a fire or heater.
3. Do not reverse the positive (+) and negative (-) terminals.
4. Do not connect the battery directly to wall outlets or car cigarette-lighter sockets without proper charging equip-
ment. Do not allow exposed ends of cables connected to opposite terminals to touch.
5. Do not put the battery into a fire or apply direct heat.
6. Do not use the battery if the battery casing has been pierced, broken, cracked, or otherwise visibly damaged.
Do not forcibly open the battery casing for any reason.
7. Avoid severe physical shock. Do not throw the battery or heavily strike the battery in any way. Do not put
excessive pressure or step on the battery.
8. Never solder anything directly to the battery terminals.
9. Do not attempt to disassemble or modify the battery in any way.
10. Do not place the battery in a microwave oven or pressurized container.
To ensure the effectiveness and longevity of your battery configuration, adhere to these essential guidelines:
1. Battery Consistency: Utilize identical batteries for parallel connections.
2. Uniform Voltage Levels: Prior to connecting in parallel, guarantee that all batteries share the same
voltage level by fully charging each individual battery. The permissible voltage difference is less than 0.2V.
3. Avoid Mixing Batteries: Do not combine old and new batteries within the same setup.
4. Parallel and Series Separation: Avoid simultaneous parallel and series connections for the batteries.
5. Circuit Limitation: Do not exceed connecting more than 10 batteries per circuit.
