BIG JOE Lithium Battery Conversion:  Lead-to-Lithium Upgrade 

At our facility, we embrace a singular engineering philosophy: "Simpler is More Reliable." By stripping away the maintenance-heavy burdens of lead-acid and replacing them with our cutting-edge LiFePO4 (Lithium Iron Phosphate) technology, we provide a "drop-in" solution that turns your fleet into a high-efficiency powerhouse.

Designed Specifically for BIG JOE

• Zero Maintenance: No watering, no cleaning, no equalization. Just install, charge, and operate—freeing your team for higher-value tasks and cutting labor costs dramatically.

• Opportunity Charging: Charge during breaks, lunch, or any short downtime without damaging the battery. One lithium pack often replaces 2–3 lead-acid batteries in multi-shift use.

• Consistent Power Delivery: Full voltage and torque from start to finish of every shift for reliable lifting speeds, acceleration, and productivity.

• Faster Charging: Full charge in 1–2 hours (or less with fast chargers) versus 16 hours total for lead-acid. Reduce or eliminate battery rooms entirely.

• Longer Lifespan: Super Long 8,000+ cycles, often 5 times longer than lead-acid, meaning lower total cost of ownership and fewer replacements.

• Energy Efficiency & Savings: Up to 60% more energy efficient, with reports of 30% lower electricity costs and thousands saved annually on maintenance.

• Safety & Environment: No acid spills, no toxic fumes, reduced fire risks with advanced BMS (Battery Management System), and better for indoor air quality.

Reliability in Every Environment

From high-throughput distribution centers to -40°C cold storage facilities, our BIG JOE-compatible packs deliver consistent voltage and high-amp discharge. You get full travel speeds and lifting power from 100% down to 5% charge—no more "sluggish" performance at the end of the day.

Upgrade your BIG JOE fleet to Lithium today for a cleaner, faster, and more profitable operation.

BIG JOE Frequently Asked Questions

Q1: Do I need to modify my Big Joe walkie stacker or adjust the counterweight to fit your lithium battery?

A: Not at all. Our lithium batteries are engineered as a true drop-in replacement tailored specifically 

for all major Big Joe models, such as the CB22 or PDH series. They match the exact dimensions 

of your original lead-acid battery compartment and come equipped with an integrated counterweight. 

Installation is as simple as lifting out the old battery, dropping ours in, and plugging in the Anderson connector. 

No chassis modifications, no rewiring, and zero impact on vehicle stability—

you can complete the swap in under 15 minutes.

Q2: Our daily warehouse workflow is unpredictable. Lead-acid batteries take 8 hours to charge; how much faster is your lithium solution?

A: You will experience a charging speed up to 4 times faster. 

Unlike lead-acid batteries that require a strict "8 hours charging + 8 hours cooling" routine, 

our lithium batteries support opportunity charging. Your operators can plug in the truck during 

a 15-to-30-minute coffee break or shift change to instantly claw back 20% to 30% of power. 

A full charge takes less than 2 hours, completely eliminating the risk of trucks sitting 

idle and delaying critical shipments during peak operational hours.

Q3: We don’t have a dedicated maintenance technician. Our old lead-acid batteries often failed due to missed water topping. How does lithium compare?

A: Our lithium batteries require absolute zero maintenance. 

The system is completely sealed, meaning no water topping, no acid-level checks, 

and zero risk of acid spills corroding your Big Joe chassis. Furthermore, the integrated 

smart Battery Management System (BMS) automatically protects the battery against over-discharging, 

over-charging, and short circuits. Even when operated by temporary or inexperienced warehouse staff, 

there is no risk of damaging the battery through improper use.

Q4: The upfront cost of a lithium battery is higher than lead-acid. How can I justify this investment to my finance team?

A: While the initial purchase price is higher, your Total Cost of Ownership (TCO) drops by over 50%.

 A standard lead-acid battery lasts only about 1,500 cycles (typically 2 to 3 years before severe degradation). 

In contrast, our industrial-grade lithium battery delivers over 8000 cycles and comes with a 10-year warranty, 

lasting 15 to 20 years. When you factor in the elimination of maintenance labor, zero watering costs, 

and significant electricity savings due to higher energy efficiency, 

you will fully recover the premium within 12 to 18 months.

Q5: Our Big Joe electric pallet jacks run heavily during peak hours. Can lithium handle continuous, heavy-duty cycles?

A: Not only can it handle it, but it also delivers far better performance. 

Lead-acid batteries experience voltage drops when the capacity falls below 50%, 

causing the forklift’s travel and lifting speeds to slow down significantly. 

Our lithium batteries feature a flat discharge curve, providing constant power output. 

Whether the battery is at 99% or 10%, your Big Joe will maintain its maximum travel 

and lifting speeds, keeping your warehouse efficiency at its peak throughout the entire shift.

Q6: We operate a compact facility without a dedicated battery room. Is it safe to charge lithium batteries right on the warehouse floor?

A: Yes, it is perfectly safe and highly convenient. Lithium batteries 

emit zero gas, zero acid mist, and zero noise during charging. 

We use premium Lithium Iron Phosphate (LFP) chemistry, 

which is the most thermally and chemically stable lithium technology available. 

The built-in BMS monitors the temperature and voltage of every single cell 24/7 

to prevent overheating. You can save valuable warehouse square footage by

 charging your Big Joe directly at the workstation, eliminating the need

 for expensive ventilated battery rooms.

Q7: Will my Big Joe’s original dashboard and Battery Discharge Indicator continue to work accurately after the switch?

A: Yes, we have achieved deep controller protocol compatibility. 

Our battery systems communicate seamlessly with the Curtis controllers 

commonly found in Big Joe trucks. Your original dashboard will accurately display 

the real-time State of Charge (SoC), completely eliminating the "floating voltage" 

or sudden gauge drops common with old lead-acid batteries. For added convenience,

 we also offer an optional external smart screen or Bluetooth App connectivity, 

allowing you to check precise battery health right from your smartphone.

Q8: We occasionally use our Big Joe in cold storage or unheated cross-docks. Will cold weather drastically kill the lithium battery life?

A: We have designed a specialized solution specifically for harsh and cold environments. 

For cold chain or freezing operations, we offer a low-temperature version equipped 

with an integrated smart self-heating system. When the BMS detects freezing temperatures, 

it utilizes energy from the charger or the battery itself to warm the cells before charging or operating. 

This ensures stable performance and seamless charging even at temperatures as low as -40℃, 

with significantly less degradation than traditional lead-acid batteries.

Q9: If a technical issue arises, how is the warranty and aftermarket support handled for an aftermarket battery brand?

A: We back our products with a comprehensive 10-year or 10,000-hour industry-leading warranty. 

Our batteries are engineered to meet strict industrial safety compliance standards and do not alter 

the mechanical or electrical integrity of your Big Joe truck. We have established a robust local 

service network and spare parts inventory. Thanks to our cloud-connected BMS, 90% of minor 

software diagnostics can be resolved remotely, while any hardware requests are handled 

by our field technicians within 24 to 48 hours.

Q10: My Big Joe truck is 4 years old. The mechanical parts are fine, but the lead-acid battery is dead. Should I upgrade to lithium or just buy a new truck?

A: Upgrading to lithium is the most cost-effective way to give your existing fleet a second life. 

Big Joe trucks are famous for their rugged, durable mechanical chassis, 

which often outlive multiple lead-acid batteries. Spending a fraction of 

the cost of a new forklift on a lithium upgrade instantly grants your older 

truck performance that surpasses a brand-new lead-acid equivalent. 

Furthermore, even when the mechanical truck eventually reaches 

its end-of-life years down the road, this lithium battery can easily be transferred

 to your next compatible Big Joe model.
