Panasonic NCA Li-ion battery cells: the PTC switch

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%…

NASA: Li-Ion Batteries – Managing Risk to Secure Reward

Source: NASA   Li-Ion batteries perform well in packing a lot of energy into a small package. That is why NASA was one of the earliest adopters of the Li-Ion battery for use in space, where the advantages of smaller batteries with a long life expectancy are numerous, from fitting nicely into the confines of…
