Secondary protection fuse
- Protects Li-ion batteries
- In addition to Secondary protection fuse that reliably shut off overcharging and overcurrent in lithium-ion batteries, we also offer high-current Current Fuse to protect electronic devices from overcurrent.
We offer a range of options to suit your needs, from low-resistance, low-profile types ideal for PCs and smartphones to high-current types for use in power tools, electric motorcycles, and drones.
