QUETZAL MINI, USB-C powered Sodium-Ion compatible battery charger performance evaluation

Andrei FOCA

Abstract:

Hobbyists and the RC industry have relied on Lithium batteries for years as their primary source of power, but with the emergence of a new technology, based on Sodium-Ion, there is now a greener alternative (Cai et al., 2024). Yet, few have replaced their batteries, and for good reasons, because most of the hobby chargers available today do not state to be supporting the new chemistry. This paper evaluates the results of several tests done on a custom theoretical maximum 66W battery charger and balancer, the QUETZAL MINI, using batteries ranging from 1 to 4 cells in series. The highest stable output recorded on a sodium-ion battery is approximately 62.4 W (16 V at 3.9 A), maintaining temperatures below 85°C.
