Our Dual Battery Discharge Converter is a professional parallel balance adapter specially designed for electric bicycles and scooters, solving the problem of short cruising range by connecting two battery packs safely. With wide 20V-72V universal voltage coverage and three current options:20A/30A/40A, it fits 24V/36V/48V/52V/60V/72V lithium battery & controller systems from 250W to 3000W ebike motors. Equipped with independent charging head port, users can charge two batteries separately without detaching wiring.

✅ Intelligent Active Balance Discharge

Real-time voltage detection for dual batteries; auto discharge higher-voltage battery first until voltage consistent, then dual batteries output power synchronously, avoid reverse charging & single battery over-damage, extend battery service life greatly.

✅ 3 Current Specs Optional:20A /30A /40A

✅ Built-in Independent Charging Port

Exclusive charging terminal reserved, charge two batteries respectively without pulling out battery plugs, convenient for daily maintenance.

✅ Premium Aluminum Alloy Housing

Integrated heat dissipation shell, high temperature resistance, stable output current, compact size easy to hide inside frame tube.

✅ Wide Universal Compatibility

DC 20V~72V full voltage range, compatible with lithium-ion / LiFePO4 batteries, most Bafang, Ananda, standard ebike controllers.

✅ Safe Multi-protection Design

Over-current, low-voltage cutoff & anti-reverse connection protection, stop output automatically when battery undervoltage to prevent cell scrap.
