Quick Answer
Meshtastic devices typically work best with lithium-ion batteries, specifically those with a high discharge rate and a capacity of at least 1000mAh. Suitable battery types include 18650 cells, 3S 18650 packs, and lithium-ion power banks.
Choosing the Right Battery Chemistry
When selecting a battery for your Meshtastic device, consider the specific power requirements of the device. Meshtastic devices, which use the LoRaWAN protocol, typically require a high discharge rate to maintain reliable communication. Lithium-ion batteries with a high discharge rate, such as those with a C-rating of 10C or higher, are well-suited for this purpose.
Battery Capacity Considerations
To ensure reliable operation, it’s essential to choose a battery with sufficient capacity. A general rule of thumb is to select a battery with a capacity of at least 1000mAh, but preferably 2000mAh or more. This will provide ample power for extended use and minimize the need for frequent recharging. For example, a 3S 18650 pack with 2000mAh capacity per cell would provide a total capacity of 6000mAh.
Real-World Examples and Guidelines
A good example of a suitable battery for Meshtastic devices is the 3S 18650 pack with a capacity of 6000mAh. This battery pack can provide up to 12 hours of continuous operation, depending on the specific device and usage patterns. Another option is a lithium-ion power bank with a capacity of 20,000mAh or more, which can provide extended power for multiple device charges. When choosing a battery, also consider the device’s voltage requirements and the battery’s compatibility with the device’s charging circuit.
