Unlike NCR18650PF and NCR18650B cells used in e-bikes, laptops, portable scientific or medical devices, the NCR18650GA and NCR20700B / NCR20700A haven’t built-in a PTC switch. Without this are truly bare-bones cells releasing all power for the drone! Note: A PTC switch (positive temperature coefficient) adds internal resistance (Ω), thus reducing performance.

Instructions
How can you prolong the lithium-ion battery lifespan. A partial discharge reduces stress and prolongs battery life, so does a partial charge. Batteries charging to 85% have a longer lifespan than enabling full charge. Although longer lasting, a less than full cycle does not fully utilize a battery. 100% DoD is a full cycle; 10%…

Silicon has the potential to help lithium-ion batteries meet 350 Wh/kg on the cell level and 235 Wh/kg on the pack level
One thing noted in Tesla’s Model S update announcement back in July is the introduction of silicon in the anode of the cell. This change enables the battery pack to deliver 90 kWh of energy on a single charge, a roughly 6% boost from the previous 85 kWh system. Although Elon Musk was trying to…
