Eurorau Internal Battery 48V14Ah

EUNORAU 48V 14Ah Battery (Samsung 35E) — Direct Fit for Max Cargo, G20 Cargo, G30 Cargo

Overview

This 48V, 14Ah replacement battery uses genuine Samsung 35E 18650 cells in a 13S4P configuration (440 mm pack length). It provides 672 Wh of usable energy with an integrated BMS for cell balancing and common safety protections — designed as a compact, drop?in pack for supported cargo e-bikes.

Benefits

• Go farther between charges — 672 Wh delivers more usable range so you stop to recharge less often.
• Carry heavier loads reliably — consistent performance under load and on climbs keeps trips predictable.
• Spend less time on maintenance — about 500 cycles of usable life reduces replacement frequency.
• Charge and ride with confidence — multi-layer safety protections help reduce risk during normal use.
• Simple installation — compact 440 mm pack and matching electrical limits make it a straightforward swap for supported cargo models.

Features

• Genuine Samsung 35E 18650 lithium?ion cells for consistent chemistry and performance.
• 13S4P cell layout providing a 48V nominal system and 14 Ah capacity.
• 672 Wh total energy for extended range on a single charge.
• Built?in BMS with cell balancing and protections for charge, discharge, current and temperature.
• Designed charge limit of 54.6 V compatible with standard e-bike chargers.
• Rated continuous discharge for sustained riding and higher short bursts for acceleration or steep hills.
• Compact 440 mm pack length sized to fit the listed cargo bike models.
