Lithium-Battery Switching Chargers

This is a family of switching chargers designed specifically for the safe, controlled charging of lithium batteries (Li-ion and LiFePO4). Thanks to switching technology, they offer high efficiency, a compact and lightweight build, and precise charge control.

How does it work?

• CC — constant current: a controlled constant current charges the battery quickly.
• CV — constant voltage: the voltage is held precisely while the current tapers.
• Automatic cut-off: charging stops when the battery is full — unlike lead-acid, lithium is never held on float.
• Switching efficiency: compact, lightweight and low-heat operation.
• Chemistry-aware: designed to work with lithium packs and their battery-management system (BMS).

Why does lithium need precise charging?

Lithium chemistry is powerful but unforgiving — the charger is the key safety component:

• Overcharging is dangerous: exceeding the correct voltage causes overheating and, in the worst case, thermal runaway and fire.
• Imprecise voltage shortens life: even a small over-voltage accelerates capacity loss and ageing.
• No proper cut-off: pushing current after full charge stresses and degrades the cells.
• Wrong charge profile: a lead-acid-style charger (with float) is unsuitable and unsafe for lithium.
