This high capacity 72V LiFePO4 battery pack uses automotive-grade cells that hold up under heavy loads. The built-in BMS protects against overcharge, deep discharge, overcurrent, and short circuits. You can monitor real-time battery health and status through optional Bluetooth connectivity, giving you peace of mind every mile you ride.

Why Choose the 72V 40Ah LiFePO4 Battery?

Safer and more reliable thanks to top-grade cells and a durable design
Long service life with thousands of charge cycles—ideal for daily use
Lightweight at just 210 x 165 x 320 mm, making installation and transport easier
Built-in smart BMS with precision voltage monitoring (2.7V–4.2V ±3mV)
Optional features like RS485, CAN communication, GPS, heating, and display

This 72V 40Ah rechargeable lithium iron phosphate battery shines in harsh environments. It performs reliably between -20°C and 50°C. When paired with heating films, it remains stable even in freezing climates. If you compare a 72V 40Ah LiFePO4 battery vs NCM, you’ll find LiFePO4 offers better thermal stability and longer life, making it perfect for high-frequency charging scenarios.

Applications Include:

Industrial vehicles like electric forklifts and airport tugs needing strong torque and consistent voltage
Heavy-duty trikes carrying over 500kg—where a 72V lithium battery for golf cart or cargo vehicle can extend range by up to 25% compared to 60V systems
Off-grid energy storage setups where 72V LiFePO4 battery deep cycle capabilities support solar inverter efficiency

Charging & Maintenance

This 72V 40Ah lithium battery with BMS charges quickly and is virtually maintenance-free. Unlike lead-acid batteries, there’s no need to top off fluids or worry about sulfation. If you plan to replace lead acid battery with 72V LiFePO4, you’ll notice reduced downtime and fewer hassles.

Choosing 60V vs. 72V Batteries

If you often drive long distances or haul heavy loads, the 72V 40Ah LiFePO4 battery for electric scooters or utility vehicles is your best bet. It delivers higher torque and better efficiency. For budget-conscious users or environments with extreme cold, a 60V battery might be more practical.

If you’re ready to buy a 72V 40Ah LiFePO4 battery, we can help you customize it to fit your needs. From communication protocols to heating options, AnengJi makes it simple to build a battery that performs exactly how you want.

What makes the 72V 40Ah LiFePO4 battery a better choice over lead-acid batteries?

The 72V LiFePO4 battery weighs less, charges faster, and lasts thousands of cycles without losing significant capacity. It’s safer, maintenance-free, and delivers stable power for electric scooters, e-bikes, and golf carts.

Can I use this battery for my electric scooter or e-bike?

Yes. The 72V 40Ah LiFePO4 battery for electric scooters and e-bikes is designed to handle high power demands while keeping weight down. It provides long range and high torque.

How long does it take to fully charge the 72V 40Ah lithium battery?

Depending on your charger, full charging typically takes 4–6 hours. Fast chargers can reduce this time. Always use a charger compatible with LiFePO4 chemistry and BMS settings.

Is it possible to customize the battery pack?

Absolutely. You can order a custom 72V LiFePO4 battery pack with features like Bluetooth monitoring, CAN communication, heating, or specific dimensions to fit your vehicle.

What’s the expected lifespan?

With normal use, you can expect over 2,500–3,500 charge cycles—much longer than standard lead-acid or NCM batteries. That’s why so many people replace lead-acid batteries with 72V LiFePO4 options.

How do I know if this battery fits my vehicle?

Before you buy a 72V 40Ah LiFePO4 battery pack, check your motor’s voltage and current specs. Make sure your controller and charger are compatible with a 72V lithium iron phosphate battery. If you’re unsure, our team can help you confirm.
