To connect a lithium iron polymer battery, gather materials like lithium cells, wires, a soldering iron, and safety gear. Identify the terminals on each cell. For a parallel connection, connect positive to positive and negative to negative. Use a resistor to balance the cells. JST SH connectors make plug-in connections easy.
Connecting Lithium Iron Polymer (LiPo) batteries requires careful attention to configuration. In a series configuration, you connect the positive terminal of one battery to the negative terminal of the next. This setup increases the overall voltage while maintaining the same capacity. For example, connecting two 3.7V batteries in series yields a total voltage of 7.4V.
In a parallel configuration, you connect all positive terminals together and all negative terminals together. This approach keeps the voltage the same but increases the overall capacity (amp-hour rating). Two 3.7V batteries in parallel will still output 3.7V, but they can deliver double the amp-hours.
Ensure you use battery connectors that match your needs to facilitate a secure connection. Always check the batteries are of the same type, age, and capacity before connecting. This practice helps maintain battery health and performance.
After establishing the connections, it’s crucial to test the setup with a multimeter. Checking voltage levels ensures safety before utilizing the battery in applications.
