What's the best way to safely connect multiple Li-ion batteries in parallel to boost power capacity?

[SanAurora]

To safely and effectively increase your power system's capacity by connecting Li-ion batteries in parallel, consider these key points. Firstly, it's crucial to use batteries that are identical in brand, model, age, and state of charge (SoC). This ensures balanced performance and minimizes risks. Secondly, pay close attention to the wiring. The gauge of the wires must be appropriately sized to handle the total current the parallel battery bank can deliver. Properly sized wiring prevents overheating and potential hazards. Thirdly, implement a connection method that ensures equal current distribution among the batteries. This approach prevents individual batteries from being overstressed, thereby extending the overall lifespan of the battery bank and maintaining optimal performance. Avoid setups that lead to uneven current distribution, as this can cause premature battery degradation and safety concerns.
