18650 12V 1/2/3/4 series polymer Lithium Battery Power Level indicator board

Description

The 1/2/3/4 series 18650 polymer power indicator board 12V lithium battery power indicator board is designed to measure and display the power level of three lithium batteries, including lithium battery packs with three strings and multiple parallels. It detects the current voltage of the batteries and controls the illumination of different LEDs to indicate the corresponding voltage value.

The specifications include an over-discharge detection voltage range of 2.3V to 3.0V with a precision of ±0.05V, a maximum working current of 3A, a transient current handling capacity of 5A, and an operating temperature range of -40°C to +80°C. The board is compatible with input voltages ranging from DC 3V to 20V and is specifically suitable for 1/2/3/4 series 18650 or polymer lithium batteries, serving as a power indicator for 12V lithium battery systems.
