How to connect Benergy Battery packs into parallel?　

Benergy Lithium batteries can be connected in parallel to make a high capacity battery packs. 

Take an example, customer buy a 48V 230Ah battery pack from Benergy and he wants to increase the capacity. 

Firstly, let us know that you need the parallel when you order battery packs from us.

Secondly, connect the battery pack correctly with professional instructions. And here's the steps:

When connecting several 48V lithium batteries in parallel, it's essential to follow some key steps to ensure safety and efficiency. Here's a general guide on how to connect multiple 48V lithium batteries in parallel:

1. Battery Selection: Ensure that all the lithium batteries you are connecting in parallel are of the same voltage (in this case, 48V) and have similar capacities and chemistries.

2. Safety Precautions: Before working with batteries, make sure to wear appropriate safety gear, work in a well-ventilated area, and avoid creating short circuits.

3. Battery Interconnections: Connect the positive terminal of each 48V battery to the positive terminal of the next battery using thick gauge wires. Similarly, connect the negative terminals of the batteries together using separate wires.

4. Balancing: To prevent imbalances between the batteries, consider using a battery management system (BMS) that can help monitor and balance the charge among the batteries in parallel.

5. Fuse Protection: Install fuses between each battery and at the connection points in the parallel setup to protect against overcurrent situations.

6. Monitoring: Implement a monitoring system to keep track of the voltages and overall health of the batteries in parallel to ensure they are functioning correctly.

7. Proper Insulation: Insulate all connections properly to prevent accidental short circuits and ensure that the connections are secure and tight.

8. Testing: Before putting the batteries into regular use, perform thorough testing to ensure that they are working as intended and that there are no issues with the parallel connection.

Thirdly, check the whole system to make sure the battery pack group is running well.
