Battery 3.7v 2600mah

3.7v 2600mah battery
a 3.7v 2600mah battery is a lithium-ion (li-ion) or lithium-polymer (li-po) rechargeable battery commonly used in electronic devices, iot projects, robotics, and portable power applications. it provides a stable voltage of 3.7v and has a capacity of 2600mah, meaning it can supply 2600ma (2.6a) for one hour or 260ma for 10 hours.

this type of battery is lightweight, compact, and offers a high energy density compared to other rechargeable batteries like nimh or lead-acid. it usually comes with built-in protection circuits to prevent overcharging, over-discharging, and short circuits, ensuring safe operation.
