What Are the Key Specifications of the 36V 40Ah LBS Lithium Battery?
The 36V 40Ah LBS Lithium Battery features a nominal voltage of 36V, capacity of 40Ah (1.44 kWh), and a weight of approximately 15-18 kg. It operates efficiently between -20°C to 60°C, supports up to 1C continuous discharge, and includes built-in BMS for overcharge, over-discharge, and short-circuit protection. Its 80% depth of discharge (DoD) maximizes usable energy.
The 36V nominal voltage is ideal for applications requiring moderate power with extended runtime, such as trolling motors or solar storage systems. The 40Ah capacity provides 1,440 watt-hours of energy, enabling sustained operation of high-demand devices. The battery’s lightweight design (50% lighter than equivalent lead-acid models) simplifies installation in mobile setups like RVs or marine vessels. Its wide temperature tolerance ensures reliable performance in harsh environments, from freezing winters to desert heat. The built-in Battery Management System (BMS) actively monitors cell balance, preventing voltage spikes and ensuring optimal charge distribution across all cells.
| Specification | 36V 40Ah LBS | Lead-Acid Equivalent |
|---|---|---|
| Energy Density | 150 Wh/kg | 40 Wh/kg |
| Cycle Life | 2,000+ | 500 |
| Charge Time | 3 Hours | 8+ Hours |
How Does the LBS Battery Outperform Lead-Acid Batteries?
Unlike lead-acid batteries, the LBS lithium battery offers 50% weight reduction, 3x faster charging, and 5x longer lifespan. It maintains consistent voltage under heavy loads, suffers no memory effect, and requires zero maintenance. With 95% efficiency versus 70-85% in lead-acid, it ensures more usable energy per cycle, reducing long-term costs.
What Safety Features Protect the 36V 40Ah LBS Battery?
The battery includes multi-layered safeguards: flame-retardant casing, cell-level fuses, temperature sensors, and a BMS monitoring voltage, current, and state of charge. It automatically disconnects during short circuits or overheating. UL1973 and UN38.3 certifications validate its compliance with international safety standards.
The flame-retardant casing uses composite materials that self-extinguish at 800°C, significantly reducing fire risks. Each cell is equipped with individual fuses that isolate faults, preventing cascading failures. Temperature sensors embedded in the core cells trigger automatic shutdown if internal temperatures exceed 65°C. The BMS provides real-time diagnostics, tracking voltage fluctuations as small as 0.05V and current deviations above 2A. These redundancies ensure compliance with marine ABYC standards and solar NEC guidelines.
| Safety Feature | Function |
|---|---|
| Cell-Level Fuses | Isolate faulty cells within 0.1 seconds |
| Thermal Sensors | Monitor 8 critical points per battery pack |
| BMS Protections | 12-layer protection against voltage/current anomalies |
“The 36V 40Ah LBS battery represents a paradigm shift in deep-cycle applications. Its modularity and adaptive BMS allow seamless integration into hybrid energy systems, while the cobalt-free LiFePO4 chemistry enhances thermal stability. For marine and solar users, it’s not just a battery—it’s a long-term power ecosystem.” — Dr. Elena Torres, Energy Storage Solutions Architect
FAQ
- How Long Does the 36V 40Ah LBS Battery Last on a Single Charge?
- Runtime depends on load: a 500W device runs ~2.8 hours at full capacity. At 50% DoD, it delivers 720Wh, sufficient for 14 hours of 50W LED lighting.
- Is the Battery Compatible with Standard Chargers?
- Yes, but use a lithium-specific charger (42V output, 20-30A) to optimize lifespan. Avoid lead-acid chargers, as their voltage curves may undercharge or damage cells.
- Can It Be Shipped Internationally?
- Yes, UN38.3 certification ensures safe air/sea transport. Some regions require MSDS sheets—confirm with suppliers beforehand.
