This Battery Management System (BMS) functions as both a power supply and a Li-Ion battery charger type 18650 and has 3 slots and a complete protection system. Very compact, it can power small systems or become a real portable battery. With its MPPT regulators, this module can therefore also operate as a charger, once powered by a voltage of 15-24V. The module has 4-level indicators to display the battery charge level.

Battery BMS Power Supply / Charger Module Lithium 18650 with Protections
This Battery Management System (BMS) functions as both a power supply and a Li-Ion battery charger type 18650 and has 3 slots and a complete protection system. The module provides an output voltage of 12V DC. Very compact, it can power small systems or become a real portable battery. With its MPPT regulators, this module can therefore also operate as a charger, once powered by a voltage of 15-24V. The module has 4-level indicators to display the battery charge level.
The integrated protection system operates constantly and monitors each cell voltage, load and discharge current, and environmental temperature to provide protection against overloads, overcurrents and excessive temperatures.
Li-Ion batteries are sold separately. We recommend these batteries LG Electronics NR18650F1L of very good quality.
In this video, the Wondom brand presents the product as well as its features and protections but also its possible applications. In the middle of the video, a series of tests allows to highlight the values measured on this charger.
