2x 18650 or 21700 cells (they must both be exactly the same cell!) Let’s first list the tools that I used: Making a battery pack is dangerous. Ensure that you have a basic understanding electricity and lipo & li-ion battery tech. This guide might not be perfect, so proceed at your own risk.
21700 batteries are lithium rechargeable batteries that come in various versions with differences in battery capacity, pulse rate, drain current, charging current, and battery terminals, among other things.
The device has spring-loaded battery holders to accommodate various battery sizes. However, 21700 batteries are 3 millimeters wider and 5 millimeters longer than 18650 batteries. For safety, use chargers that explicitly state they are compatible with 21700 batteries.
Hold the lipo by all of its wires and use the heat gun to carefully heat the shrink tube. Your pack is now finished: Since we used Samsung INR21700-50E cells, this battery pack is a 2S pack with 5000 mAh. Even though these are Li-Ion cells, they are charged to 4.2 V. The cut-off voltage is a mere 2.5 V!
Making a battery pack is dangerous. Ensure that you have a basic understanding electricity and lipo & li-ion battery tech. This guide might not be perfect, so proceed at your own risk. Using battery cells incorrectly may lead to fire and physical harm. Treat them with the respect that they deserve.
Even though these are Li-Ion cells, they are charged to 4.2 V. The cut-off voltage is a mere 2.5 V! You can charge at maximum 4900 mA, but it’s advised to charge them slower. They can be discharged at 9800 mAh continuously, or 14700 mA pulse. (according to this page)
The global industrial and commercial energy storage market is experiencing explosive growth, with demand increasing by over 250% in the past two years.
