BG21 is a high-performance battery fuel gauge module suitable for various common batteries such as 6V to 48V li-ion batteries, LiFePO4 batteries, lead-acid (SLA, VRLA, GEL, AGM) batteries, NIMH/NICD batteries, and so on. She can measure battery voltage, charge/discharge status, charge/discharge current, state of charge (SOC), SOH, true battery capacity (Ah), charging curve, discharge curve, operating time, and other data. BG21 uses a Coulomb integral algorithm to accurately calculate the Ah capacity value of the battery and draw a charge discharge curve. BG21 is embedded with an automatic learning algorithm that can automatically learn the parameters of the currently connected battery, making it convenient for users to connect various types of batteries.
