Product Overview

The 72V 50Ah LiFePO4 battery is designed to address common challenges in electric tricycles, including limited driving range and excessive battery weight. Optimized PACK configurations help control the battery’s weight and dimensions, keeping the complete battery pack at approximately 36 kg while improving energy density.

Compared with a lead-acid battery of similar specifications, it offers easier installation with a compact 450 × 330 × 185 mm enclosure. Its optimized internal structure provides more usable energy within a similar footprint, while the integrated high-performance Battery Management System (BMS) delivers stable power and comprehensive protection for daily commuting and light cargo applications.

Why Choose This Lithium Ion Battery?

This battery uses advanced nickel-manganese-cobalt chemistry, delivering 20% higher energy density compared to LiFePO4 (LFP). It works reliably across a wide temperature range, from -20°C to +60°C, making it a safe lithium ion battery for both extreme cold and hot conditions.

Higher Energy Density: 20% more capacity than LiFePO4 in the same size.
Wide Temperature Range: Operates from -20°C to +60°C without losing stability.
Fast Charging: Standard 3A charging (4–6 hours full) or optional 5A fast charging (just 2.5 hours).
Cost-Effective: Over a 5-year period, the per-charge cost is as low as $0.05, four times cheaper than lead-acid.
Eco-Friendly: Fully recyclable and compliant with EU ELV standards, reducing heavy metal pollution and supporting sustainable supply chains.
