What Is Taylor Dunn Stepsave SS536 Personnel Carrier Battery?
The Taylor Dunn Stepsave SS536 personnel carrier battery is a custom-designed 48V–72V power system optimized for industrial electric vehicles. Built with lithium-ion (LiFePO4/NMC) or lead-acid cells, it ensures sustained torque and 8–10 hour runtime for material transport. Key features include ruggedized casings, CAN-Bus communication, and IP67 waterproofing. Charging uses industrial-grade CC-CV protocols at 58.4V (48V systems) or 87.6V (72V) to extend cycle life beyond 2,000 charges.
What technical specs define the SS536 battery?
The SS536 battery operates at 48V or 72V nominal with capacities from 150Ah to 250Ah. Lithium variants use prismatic LiFePO4 cells (3.2V each) arranged in 15S (48V) or 22S (72V) configurations. Built-in BMS prevents overcurrent (≥200A peak) and cell imbalance. Pro Tip: Always verify terminal polarity—reverse connections fry CAN-Bus modules. For example, a 72V 200Ah lithium pack delivers 14.4kWh, powering 12–15 personnel trips per charge in warehouse settings.
| Parameter | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 2,000+ | 500 |
| Energy Density | 140 Wh/kg | 35 Wh/kg |
| Maintenance | None | Monthly watering |
Where is the SS536 battery commonly used?
These batteries power industrial personnel carriers in airports, factories, and campuses. Their high torque (≥220 Nm) supports 2,000 lb payloads on 15% grades. Unlike golf cart batteries, SS536 packs have reinforced terminals to withstand vibration. A real-world example: Las Vegas Convention Center uses 72V SS536 systems for 12-hour shuttle operations. Pro Tip: Avoid partial charging—lithium cells last longer with 100% DoD cycles.
How to maintain SS536 batteries?
For lithium models, perform monthly voltage audits (cell deviation <50mV) and update BMS firmware annually. Lead-acid requires electrolyte checks and terminal cleaning. Warning: Never expose LiFePO4 packs to temps >60°C—thermal runaway triggers at 80°C. Imagine a car engine: just as oil changes prevent wear, voltage balancing extends battery life.
What’s the battery’s expected lifespan?
LiFePO4 SS536 batteries last 6–8 years (2,000 cycles at 80% DoD), while lead-acid degrades in 2–3 years. Depth of discharge (DoD) is key—100% DoD on lithium reduces cycles by only 15% vs. 50% for lead-acid. Pro Tip: Store carriers in climate-controlled areas; -20°C storage slashes lithium capacity by 30% temporarily.
| Factor | Impact on Lifespan |
|---|---|
| High Temps | Accelerates degradation 2x |
| Partial Charging | Increases cell imbalance risk |
| Peak Loads >200A | Reduces cycles by 25% |
Can I replace lead-acid with lithium in an SS536?
Yes, but retrofit kits must include voltage-compatible chargers and adapter plates. Lithium’s 50% weight reduction improves efficiency but requires controller recalibration. For example, swapping 48V lead-acid (800 lbs) for lithium cuts weight to 400 lbs, adding 18% range. Warning: Bypassing factory wiring harnesses voids warranties.

FAQs
Only if voltage/BMS protocols match—measure tray dimensions and consult pinout diagrams before cross-installing.
How much does a replacement battery cost?
Lithium packs run $4,000–$6,000 (72V 200Ah), vs. $1,200–$1,800 for lead-acid. Factor in 3x longer lifespan for lithium’s lower TCO.
