Features and Construction

This charger combines essential electronic safeguards with a robust build. Its core functions are supported by clear input and output parameters, ensuring consistent performance with compatible batteries.

Pulse Repair and Auto Power-Off

The pulse repair function sends regulated pulses to break down sulphation crystals on lead-acid battery plates, which can otherwise reduce capacity and life. The automatic power-off feature stops charging when the battery reaches full voltage, protecting both the charger and battery from overcharge damage.

Alloy Shell and Build Quality

The alloy shell is chosen for its strength and ability to dissipate heat generated during charging. This material helps keep the internal components cool during extended charging cycles, contributing to reliable operation. The charger's compact dimensions (192 x 98 x 66 mm) make it portable and easy to store.

Electrical Specifications

Operating on an input voltage of AC180-240V, the charger outputs 88.8V ± 0.2V at 2.6-2.9A. This output is specifically designed for 72V20Ah lead-acid battery packs, delivering a controlled current that balances charging speed with battery safety.

Uses and Placement

This charger is intended for household and light commercial use with compatible electric vehicles. Its versatile compatibility and multiple plug options make it practical for different regions.

Event or Professional Use

For delivery riders, warehouse operators, or fleet managers using electric scooters or bikes with 72V20Ah lead-acid batteries, this charger provides a consistent charging solution. The automatic power-off reduces the need for supervision, allowing overnight or between-shift charging without risk of overcharge.

Everyday Home Use

Home users can charge their electric scooter or bike daily with confidence. The pulse repair function may help maintain battery health over several months of routine use. The compact alloy case sits neatly on a garage shelf or floor and can be unplugged when not needed.

Compatibility and Portability
