🚨 Heading to the 138th Canton Fair? Let’s Meet!
📍 Hall 14.3, Booth C28-29
📅 Oct. 15–19 | Guangzhou, China

Excited to invite you to our booth at this season’s Canton Fair — where we’ll be showcasing a diverse range of LiFePO₄ battery systems tailored for real-world applications:

🔋 LiFePO₄ replacements for SLA batteries
🧱 Wall-mounted energy storage batteries
📡 Communication base station battery systems
🏌️ Golf cart batteries – high performance, long cycle
🏠 Stacked/home energy storage systems (ESS)
🔌 DIY DC expansion modules for custom builds
🚨 Portable/mobile emergency power (trolley box style)

Whether you're an installer, distributor, or project integrator, we’d love to explore how we can support your storage needs.

📩 DM me to schedule a time, get an invitation letter, or request exhibitor access.
Let’s build smarter, safer, and cleaner energy systems — together!

Can Your Battery Really Run a 2HP Air Conditioner for 10 Hours?

One of our clients just tested this combo in a real off-grid system:

Battery: 51.2V 314Ah LiFePO₄ (≈16kWh)
Inverter: 5kW Hybrid
❄Load: 2HP Vertical Inverter Air Conditioner
Discharge Current: 30A
Runtime: Nearly 10 HOURS continuous cooling
Location: Villa project, Riyadh (Middle East climate, 35°C)

✅ No tripping
✅ Stable BMS current
✅ Battery voltage held throughout discharge
✅ Customer was extremely satisfied

Why does this matter?
Because most “on paper” battery setups can’t deliver what the customer expects when heavy loads like air conditioners are involved.

We don’t guess.
We measure.
And we help you size your system properly — based on actual current, not brochure numbers.

📩 Want us to estimate how long your A/C can run on battery?

Just comment "RUNTIME" below or send me a DM — I’ll send you our calculation sheet + real-world examples.

I keep hearing the same thing from fleet managers across Southeast Asia: lead-acid batteries are a constant source of pain.

Dead starts. Idling just to keep the A/C running. Fuel bills that don’t make sense. And unhappy drivers.

Is your fleet dealing with the same issues — or have you found a way around them?

👉 Why does a 24V 230Ah battery only power an air conditioner for about 4 hours?

Here’s the truth:
🔹Rated capacity is tested in controlled lab conditions (low current, 25°C).
🔹Real-world loads like AC units demand higher, fluctuating current.
🔹Safety settings (like our 10% reserve for engine start/stop) protect the battery but reduce usable time.

Our approach:
🔹Provide realistic runtime estimates based on application.
🔹GPS monitoring to track real-time current, voltage, and SOC.
🔹One-click start/stop to avoid deep discharge and extend lifespan.

buyers know not just “how long”, but also “why”.

👉 How do you currently calculate expected runtime when sourcing batteries?

Hot.
Humid.
Non-stop.

That’s how fleets in Southeast Asia run every single day.

And the big worry I hear?
👉 “Will LiFePO₄ batteries really last in 45°C… and what if they fail on the road?”

The truth?
✅ Stable at high temps (45–55°C).
✅ 2000+ cycles under heavy start-stop.
✅ Backed by 5 years warranty + local support.

Reliability isn’t optional here — it’s survival.

Would you still trust lead-acid in these conditions?
