4. Setup

Initial Inspection:

Upon receiving your battery, inspect it for any signs of physical damage. Verify that all included accessories (e.g., terminal caps, bolts) are present.

Terminal Connections:

Connect cables securely to the battery terminals using the provided M8 bolts. Ensure positive (+) terminals are connected to positive and negative (-) to negative. Overtightening can damage terminals.

Series and Parallel Configuration:

This battery supports up to 4 batteries in series (4S) and 4 batteries in parallel (4P). For series connections, it is recommended to use TCBWORTH batteries specifically designed for higher voltages (24V, 36V, 48V) for a more stable system and longer service life, avoiding complex connections.

Parallel Connection: Connect positive terminals together and negative terminals together to increase overall capacity while maintaining the same voltage.

Series Connection: Connect the positive terminal of one battery to the negative terminal of the next battery to increase the overall voltage. Ensure all batteries are of the same voltage and capacity when connecting in series or parallel.
