This document provides essential safety and configuration guidelines for installing Eco Worthy 12V LiFePO4 lithium batteries in series or parallel systems. Adhering to these specifications is critical to ensure personal safety and system integrity.
Series-Parallel Rules
When connecting batteries, you must strictly follow the voltage-specific limitations to avoid safety risks. The maximum number of batteries allowed depends on the system voltage:
- 12V Systems: Maximum 4 in series, 4 in parallel (Total series-parallel connection ≤ 8).
- 24V Systems: Maximum 2 in series, 4 in parallel (Total series-parallel connection ≤ 4).
- 36V/48V Systems: Maximum 1 in series, 2 in parallel (Total series-parallel connection ≤ 2).
Busbar Configuration Standard
When connecting batteries in parallel, current concentration in specific branches can create safety hazards. To balance the current across all parallel branches, it is strongly recommended to use a busbar for connection whenever the number of parallel-connected batteries reaches 3 or more.
Battery Switch and Circuit Breaker Configuration
For systems utilizing batteries with a single-battery capacity of 100Ah or higher, specific circuit protection is required:
- Series Connection: It is recommended to install a circuit breaker in the main circuit.
- Parallel Connection: It is recommended to install additional circuit breakers in each individual branch circuit.

Common problems
Current concentration in parallel branches
Use a busbar for connection if you are connecting 3 or more batteries in parallel to balance the current.
Safety risks in high-capacity systems (100Ah+)
Install a circuit breaker in the main circuit for series connections, or in each branch circuit for parallel connections.
Before use
- Verify the total system voltage (12V, 24V, 36V, or 48V).
- Check the maximum allowed series and parallel quantities for your specific voltage.
- Ensure a busbar is available if connecting 3 or more batteries in parallel.
- Confirm if your battery capacity is 100Ah or higher to determine circuit breaker requirements.
Specs in practice
- Series-Parallel Connection Limit
- The total combined limit of batteries allowed in a specific configuration to maintain safe operation.
Images and diagrams
- The busbar diagram illustrates how to connect multiple batteries to a common load using busbars to ensure balanced current flow.
- The circuit breaker diagrams show the correct placement of breakers in the main circuit (for series) versus individual branch circuits (for parallel) for high-capacity systems.
Model compatibility
- Rules vary significantly based on system voltage (12V vs 24V vs 36V/48V).
- Specific circuit breaker configurations are mandatory for systems using batteries with 100Ah capacity or higher.
