Welcome to the BatteryTester wiki!
This is a tester for 18650 lithium batteries. Each tester board has an ESP32 chip that manages the testing functions for two cells. Each tester board communicates with an MQTT broker running on a raspberry Pi. The number of tester boards per test system is limited by the power supply, each tester requires a maximum of 2 amps, so a test jig with 10 boards would require at least a 20 amp 5V power supply and would be able to test 20 cells at a time.
