Charger Not included! Listing is for 1 off, 18650 battery. Sodium-ion High Discharge, Cells, They provide energy efficient power with fast charging, stability against temperature extremes and safety against overheating or thermal runaway.& nbsp

In contrast, the safety of sodium batteries is much higher than that of lithium and NMC batteries.In tests such as overcharge and discharge, short circuit, acupuncture, etc., it can be achieved without fire or explosion. The biggest advantage of sodium batteries is not only safety, but also low cost.
