Prototyping and Engineering Tips from Robogears

• Quality Verification: Always use the weight as a benchmark. Low-quality cells often weigh between 25g and 32g; this 42g original cell ensures you aren't using a "sand-filled" or low-capacity counterfeit.

• Battery Pack Assembly: If you are building a 12V pack (3S configuration), always use cells of the same weight and capacity. This 2000mAh cell is perfect for 12V drones or small RC cars when paired with a 3S BMS (Battery Management System).

• Over-Discharge Warning: As an "unprotected" industrial cell, it does not have internal circuitry to cut off power. Ensure your project has a low-voltage alarm or a protection module to prevent the cell from dropping below 2.5V, which can cause permanent chemical damage.

• Safe Soldering: If you do not have a spot welder, use a high-heat soldering iron (60W+) and pre-tin the wire. Apply heat for no more than 2 seconds to the terminal to prevent the internal separator from melting.
