These round high capacity cells have been mainly used in flashlight type applications but with its capability to be used as a drop-in rechargeable cell at 3

FSR Integration Guide

Industrial 4-Channel Relay Module Shipping:2-4 Weeks GPS Real Time Kinematics (RTK)The module adopts the standard Modbus RTU protocol, the communication interface supports RS485 or RS232 and supports communication baud rates of 2400, 4800, 9600, 19200, 38400 (default 9600). Each relay output is independent and can be connected to different load devices, such as 24V solenoid valves, etc. Both AC and DC devices can be controlled. Each relay output contact is isolated and can set 0 255 device addresses. It can be switched on and off
