From retro-style desk fans to modern circulating fans, XUNFEI manufactures the control PCBA that delivers quiet, energy-efficient and reliable operation — proven in real mass-produced products.
High-current, high-reliability PCBs for energy storage BMS, solar PV inverters, PCS, EV charging piles, onboard power, lithium battery protection and wind power control modules.
The "energy manager" of new-energy vehicles is this very board. The BMS battery-management PCBA integrates a main controller, high-current MOSFETs, and cell-sensing and balancing circuits to monitor the voltage, current and temperature of every cell in real time — balancing charge/discharge and delivering precise protection for a safe, long-lasting, efficient battery pack. AEC-Q100 automotive design, high-temperature and vibration tolerant — responsible for the safety of every watt.
Charging should be this simple. Our AA USB rechargeable lithium battery comes with a built-in TYPE-A/USB plug — pull it out, align it with a USB port, plug it in, and charging begins.
9V devices never lack applications — they lack a battery that truly understands them. We specialize in the electronic design and manufacture of rechargeable lithium batteries, built on protection PCBs, charging-management ICs and constant-voltage output circuitry.
Charge four at once, in perfect order. Four independent charging slots top up 4 AA/AAA batteries simultaneously without interference, intelligently detecting battery type — compatible with 1.5V lithium as well as Ni-MH and Ni-Cd rechargeables.
We specialize in the electronic design and manufacture of portable car jump starters, built on intelligent protection PCB, super-capacitor / high-rate cell technology and compact PACK engineering.
We deliver complete power solutions for every kind of electronic device — from individual cells to fully assembled battery packs. Every cell passes automated production, capacity grading and rigorous quality control, giving your products a more stable, longer-lasting energy core.
