Massive Weight Savings: You’ll cut up to 75% of the battery weight, which means faster speeds and less wear on your tires/brakes.
Zero Maintenance: No more watering batteries or cleaning acid corrosion. Just charge and go.
Flat Voltage Curve: Your cart won’t slow down as the battery gets low. It stays fast until the very end.
Extended Range: Our lithium tech lets you “play harder and last longer” compared to old-school batteries.
Fast Charging: Optimized for rapid turnaround times—get back on the road in a fraction of the time.
Lower Total Cost: It lasts 8-10x longer, so you actually save money over the life of the vehicle.
Direct Drop-in: It’s designed to fit existing 72V battery compartments with minimal effort.
Superior Safety: LFP chemistry is the safest lithium on the market. It won’t catch fire under harsh conditions.
No Hidden Fees: Our DDP shipping means the price you see is the price you pay. No surprises at customs.
Scalable Design: We can parallel multiple units if your project needs 150Ah, 225Ah, or more.
Cold Weather Performance: Better discharge rates in chilly weather than lead-acid competitors.
Eco-Friendly: No lead, no acid. It’s the “green” choice for modern brands.
Real-Time Data: Use the CAN/RS485 port to see exactly how much “juice” is left.
High Efficiency: 98% efficiency means almost no energy is wasted during charging.
Expert Support: You’re talking to engineers, not just salesmen. We help you integrate the battery perfectly.
Electric Vehicles: Ideal for Golf Carts, Utility Vehicles (UTV), and Low-Speed Vehicles (LSV)
Marine & Boats: High-power source for outboards and electric propulsion systems
Material Handling: Perfect for Electric Forklifts and warehouse equipment
Industrial Mobility: Reliable power for Electric Wheelchairs and Power Systems
* Based on field testing in Golf Carts and Marine environments, our BMS is optimized to handle the peak surge currents required for heavy-duty propulsion
“Is the Bonnen 72V 75Ah battery a direct fit for my EZGO or Club Car?”
Yes! We designed this to be a drop-in replacement. You just swap the old batteries out and put this one in. It fits most standard 72V compartments.
“How many cycles can I expect from this LiFePO4 battery?”
You’re looking at 3,500+ full charge/discharge cycles. For most users, that’s over 10 years of daily use.
“Does the BMS support high-performance motor controllers?”
Absolutely. Our BMS handles a peak of 225A, so it works perfectly with brands like Navitas or Curtis controllers.
“Can I monitor battery status via RS485 or CAN?”
Yes, we can customize the communication protocol to match your vehicle’s dashboard or controller for real-time monitoring.
“What is the weight difference between this lithium battery and lead-acid?”
It’s a huge difference! A 72V lead-acid bank usually weighs around 300+ lbs. Our 72V 75Ah pack is about 75-80 lbs.
“Are customs duties and VAT included in the shipping to Europe/USA?”
If you choose our DDP shipping option, yes. We handle all the paperwork and taxes so it arrives at your door ready to use.
“Can I use this 72V battery for an electric outboard motor?”
Yes, it’s great for marine use because it’s sealed and provides the high current needed for electric propulsion.
“What happens if the battery arrives damaged during sea freight?”
We use heavy-duty packaging, but if anything happens, our 5-year warranty and shipping insurance cover it. We’ll get you a replacement ASAP.
“Is it possible to connect multiple 72V 75Ah units in parallel?”
Yes, you can connect them in parallel to increase your total capacity (Ah) for even longer range.
“What are the storage requirements for the battery during winter?”
Lithium loves being stored at 50-70% charge. Unlike lead-acid, it won’t die if you leave it for a few months, but keep it in a cool, dry place.
“Does Bonnen Battery ship to remote regions like the Canary Islands?”
We ship globally! Just let us know your location, and we’ll find the best route.
“How does the 5-year warranty work if I have a technical issue?”
Simply contact us with the battery ID. We provide remote diagnostics first, and if there’s a hardware fault, we ship parts or a replacement.
“Is LiFePO4 safer than other lithium chemistries for RV use?”
Definitely. LiFePO4 is much more stable than the NCM lithium used in phones. It doesn’t have the “thermal runaway” risks.
“How long is the handling time for orders shipping from China?”
Usually, production takes 2-4 weeks depending on customization, and shipping takes another 4-6 weeks by sea.
“Do I need a special charger for this LiFePO4 battery?”
Yes, you need a LiFePO4-specific charger (set to 14.6V per 4-cell block, or roughly 87.6V for a 72V system). We can provide this with your order!
“How to charge a 72V lithium battery safely?”
It’s easy: use a dedicated LiFePO4 charger, plug it into a standard outlet, and the BMS will automatically stop the charge when it’s full.
“72V battery installation guide for golf carts?”
It’s a 3-step process: 1. Remove old batteries. 2. Place the Bonnen pack in the center. 3. Connect the positive and negative leads. Done!
