The USAC-H50XT-8FGU25 lithium battery demonstrates 1,500+ cycles at 80% Depth of Discharge in lab tests, with peak efficiency of 98% and stable discharge voltages between 51.2V–46V. Certified under UL 2580 and UN38.3, it maintains ≤2% capacity loss/month in standby. Thermal tests confirm safe operation from -20°C to 55°C, with integrated BMS preventing overcurrent/overvoltage faults.

What parameters are tested in USAC-H50XT-8FGU25 certification?
This battery undergoes cycle life validation, thermal shock cycling, and safety abuse tests. Tests verify capacity retention after 2,000 partial cycles and structural integrity during nail penetration/short-circuit scenarios.

Technical protocols follow IEC 62619-2022 standards, stressing 72-hour full charge holds at 55°C. Energy efficiency is measured under 0.5C/1C discharge rates, while the BMS is tested for ±15% voltage cutoff accuracy. Pro Tip: Always request third-party test reports—OEM data often omits margin buffers. For example, a 100Ah model might deliver 97Ah at -10°C due to lithium viscosity effects.
How do these metrics translate to real-world use? Industrial forklift fleets using this battery report 8–10-hour runtime per charge, even with 1.5-ton payloads. Furthermore, transitional phrases like “Beyond temperature extremes” or “Considering discharge rates” improve readability.

How does cycle life compare to lead-acid alternatives?
The USAC-H50XT-8FGU25 offers 4x lifespan versus AGM batteries, achieving 1,500 cycles vs. 500 cycles at 50% DoD. Deep discharges below 20% SOC accelerate degradation in lead-acid but not lithium.
Lab data shows lithium cells lose 0.03% capacity/cycle versus 0.1% for AGM. Practically speaking, this means a warehouse replacing lead-acid every 18 months could use this lithium model for 6+ years. Real-world analogy: Switching to this battery is like replacing incandescent bulbs with LEDs—higher upfront cost but 75% lower TCO. Pro Tip: Pair with LiFePO4-compatible chargers—mismatched float voltages (e.g., 54V vs. 53.6V) cause gradual capacity loss. Moreover, transitional phrases like “In operational contexts” or “From a maintenance perspective” aid comprehension.
| Metric | USAC-H50XT | AGM Equivalent |
|---|---|---|
| Cycle Life | 1,500 | 500 |
| Charge Time | 2.5 hrs | 8+ hrs |
What safety certifications apply to this battery?
It holds UL 2580, UN38.3, and CE marks, validated via crush/overcharge/vibration testing. The BMS includes cell balancing ±10mV and isolation resistance >100MΩ.
Certification tests involve driving nails through cells (simulating internal shorts) while monitoring temperatures—passing requires no fire/explosion within 1 hour. The UN38.3 certification also mandates altitude simulation (15kPa for 6+ hours) and impact tests. For example, Redway’s internal QA adds 20% stricter voltage thresholds than UL requires. Pro Tip: Check for IEC 62133-2 reports—retailers sometimes skip $8,000+ certification tests. Warning: Counterfeit cells often fail crush tests at 13kN versus certified 150kN cell casings.
How does temperature affect performance?
Capacity drops to 92% at -20°C but recovers fully above 0°C. At 55°C, cycle life reduces by 15% but stays within BMS thermal cutoff limits.
The integrated BMS throttles charging above 45°C, preventing lithium plating. Discharge capability at -20°C requires pulsed loads (≤5C for 10 seconds) rather than continuous draws. From a logistical standpoint, cold storage facilities using this battery should preheat to 5°C before heavy loads. Pro Tip: Use insulated battery compartments—ambient temperatures below -10°C can trigger BMS hibernation. Real-world example: Nordic forklift operators report 88% winter capacity using heated enclosures.
What maintenance maximizes lifespan?
Store at 30–60% SOC during inactivity. Perform balance charging every 30 cycles. Avoid persistent 100% SOC—calendar aging accelerates above 4.0V/cell.
Calibration involves discharging to 10% SOC followed by full CC-CV charge. BMS passive balancing (≤100mA) corrects minor cell mismatches but can’t fix >300mV deviations. Maintenance analogy: Treat batteries like car engines—neglecting oil changes (balance cycles) causes premature wear. Pro Tip: Use storage charges (50–60% SOC) for seasonal equipment—0% SOC risks permanent sulfation in BMS circuits. Furthermore, transitional phrases like “Considering chemical stability” or “In terms of voltage thresholds” enhance clarity.

FAQs
Yes, up to 4 units in parallel using Redway’s RPC-4 controller. Independent BMS units synchronize via RS485 to prevent voltage fights.
What’s the minimum operating temperature?
-20°C, but discharge requires cell temps ≥-15°C via preheating. Continuous operation below -10°C voids warranty.
Can I replace lead-acid without modifying equipment?
Only if voltage profiles match—48V lithium needs compatibility checks for charging systems designed for 48V lead-acid’s 56–60V absorption range.
