Open in editorWiring batteries in parallel is one of the most common ways to increase your system's capacity. This diagram shows two 100Ah lithium batteries connected in parallel, giving you 200Ah total capacity while maintaining 12V. The parallel bank feeds through a 200A main fuse to a 1000W inverter for AC power.
When connecting batteries in parallel, it's critical to use identical batteries (same chemistry, capacity, and age) and equal-length cables to ensure balanced charging and discharging. The fuse between the battery bank and inverter protects against short circuits and overcurrent.
