How do you assemble the battery pack step-by-step?
Here’s a step-by-step guide to assembling your 12V 560Ah lithium battery pack:
- Prepare the Cells: Gather your LiFePO4 cells and ensure they are all at similar voltage levels before starting assembly.
- Connect Cells in Series/Parallel: Depending on your configuration, connect the cells using nickel strips:
- For a 12V configuration, connect four cells in series (each cell typically provides about 3.2V).
- Ensure proper polarity when connecting.
- Solder Connections: Use soldering equipment to secure connections between nickel strips and cells, ensuring no short circuits occur.
- Install BMS: Connect the BMS according to its wiring diagram, ensuring it monitors each cell’s voltage correctly.
- Insulate Connections: Use heat shrink tubing to cover all exposed connections for safety.
- Encase the Battery Pack: Place the assembled battery into a protective casing to shield it from physical damage.

What safety precautions should be taken during assembly?
Safety is paramount when assembling lithium batteries. Follow these precautions:
- Wear Protective Gear: Always use gloves and goggles to protect against accidental spills or short circuits.
- Work in a Ventilated Area: Ensure good airflow to avoid inhaling fumes from soldering or potential gas release from batteries.
- Avoid Overheating: Be cautious not to overheat cells during soldering; excessive heat can damage them or cause thermal runaway.
- Keep Flammable Materials Away: Maintain a clean workspace free from flammable items to reduce fire risk.
- Inspect Components Regularly: Check for any signs of wear or damage throughout the assembly process.
