Renesas launches a Li-ion battery management platform, including fuel gauge ICs, MCU and pre-validated firmware at APEC 2025.

Renesas introduced all-in-one solutions for managing lithium-ion battery packs in a wide range of battery-powered consumer ...

The typical way of doing a low battery detector is throwing a comparator in the circuit, setting it to measure a certain threshold voltage, and sending that signal off to a microcontroller or ...

It also has a "fuel" gauge which will show 56V 5000mah battery's level of charge, letting you know when they reach 15%, you can always be able to compare the battery's condition as they age.
