12.6V 5A 63W Desktop Li-ion Battery Charger for 3S Packs | Guangdong QINX

The Guangdong QINX 12.6V 5A Li-ion battery charger is designed for 3-cell lithium-ion battery configurations used in portable electronics, embedded systems, and compact power solutions. With a 5A output capability, it significantly improves charging speed while maintaining stable electrical performance and safe temperature control.

This charger adopts an advanced CC/CV charging algorithm optimized for lithium-ion chemistry. It ensures stable current delivery during the initial charging phase and precise voltage regulation during the final stage, effectively preventing overcharging and protecting battery longevity.

A wide 100–240VAC input range allows global compatibility, making the charger suitable for international markets without additional voltage adaptation. It is widely adopted by OEM manufacturers for integration into consumer electronics and industrial devices requiring reliable standardized charging modules.

Compared with lower-current models, the 5A version is ideal for medium-to-large capacity battery packs where reduced charging time and stable performance are critical. Guangdong QINX provides flexible customization services, including connector selection, cable length, housing design, branding, and packaging solutions.
