What Are The Specifications Of The 105Ah MD Lithium Battery?
The 105Ah MD lithium battery is a high-performance LiFePO4 power solution characterized by its 51.2V nominal voltage and 105Ah rated capacity, delivering 5.38kWh energy storage. Designed with prismatic cells in a 16S1P configuration, it supports 200A continuous discharge (peaking at 300A) and achieves over 4,000 cycles at 80% depth of discharge. Critical specifications include a 58.4V charging cutoff, -20°C to 60°C operational range, and integrated 300A BMS with thermal protection. Compact dimensions (470×296×280mm) and 49kg weight enable easy integration in golf carts and solar storage systems.
What is the voltage profile of the 105Ah MD battery?
This LiFePO4 system operates between 44V (cutoff) and 58.4V (full charge), maintaining stable 51.2V nominal. Why does voltage range matter? The 3.2V/cell chemistry prevents voltage sag during high-current demands—critical when powering 5kW+ golf cart motors. Pro Tip: Use active balancing BMS to maintain ≤50mV cell variance during rapid charge/discharge cycles. For example, a 48V-105Ah golf cart battery typically delivers 80-100km range per charge at 25km/h cruising speeds.
How does temperature affect performance?
The MD battery maintains -20°C to 60°C operational range with optional heating pads. Below -10°C, discharge capacity drops 15-20% due to increased internal resistance. Thermal management becomes crucial in desert climates where ambient 45°C temperatures can push cells beyond 60°C without cooling. Practical Example: At 40°C ambient, runtime decreases 8% hourly due to BMS throttling. Always monitor temperature via the mobile app during extreme conditions.
| Condition | Capacity Retention | Cycle Life |
|---|---|---|
| 25°C | 100% | 4,000+ |
| 45°C | 92% | 3,200 |
What safety features are integrated?
Advanced 300A BMS provides seven-layer protection: overcharge (58.8V cutoff), over-discharge (44V cutoff), short circuit (10μs response), overcurrent, temperature extremes, and cell balancing. The fire suppression system activates at 150°C using aerosol-based extinguishers. Pro Tip: Replace extinguisher cartridges every 3 years—degraded suppressants won’t contain thermal runaway effectively.
How does cycle life compare to lead-acid?
The MD battery achieves 4,000+ cycles versus 500-800 in AGM counterparts. Even at 100% daily cycling, it outlasts lead-acid by 6-8 years. Cost analysis shows 72% lower TCO over a decade. Example: A 105Ah AGM battery requires 18 replacements to match one MD lithium unit’s lifespan, costing 3.2× more in total.
| Parameter | LiFePO4 | AGM |
|---|---|---|
| Cycle Life | 4,000 | 700 |
| Weight | 49kg | 68kg |
| Efficiency | 98% | 80% |
What charging infrastructure is required?
A 22A smart charger achieves 0-100% in 5 hours via CANbus communication. The CC-CV protocol transitions from 58.4V bulk charge to float at 54.4V. Why avoid generic chargers? Non-synchronized units cause BMS conflicts, triggering error codes. Pro Tip: Implement multi-stage charging with temperature compensation (3mV/°C) to prevent overvoltage in cold environments.

FAQs
Yes in 90% of applications, but verify alternator/charger compatibility—AGM systems often lack voltage precision for lithium chemistries.
What’s the shelf life when not in use?
3% monthly self-discharge vs. 15% in AGM. Store at 50% SOC and 15°C for optimal longevity during extended storage.
