Yes, you can connect 18650 batteries in series to increase the overall voltage of your battery pack. However, it is crucial to ensure that all batteries are of the same type, capacity, and charge level to maintain safety and efficiency. Proper balancing and protection circuits are essential to prevent damage and ensure longevity.
Understanding Series Connections of 18650 Batteries
Connecting 18650 batteries in series involves linking the positive terminal of one battery to the negative terminal of the next. This configuration adds the voltages of each battery while maintaining the same capacity (Ah). For example, connecting two 3.7V 18650 batteries in series results in a total voltage of 7.4V.
| Configuration | Voltage Output | Capacity (Ah) | Applications |
|---|---|---|---|
| Single 18650 | 3.7V | 2-3 Ah | Small electronics |
| Two in Series | 7.4V | 2-3 Ah | eBikes, power tools |
| Three in Series | 11.1V | 2-3 Ah | Electric vehicles |
