What Are The Features Of The 60Ah MD Lithium Battery?
The 60Ah MD lithium battery is a high-capacity energy storage solution designed for demanding applications requiring stable power output and extended runtime. With a nominal capacity of 60 ampere-hours (60000mAh), it delivers consistent performance across electric vehicles, solar storage systems, and industrial equipment. Built with lithium-ion chemistry, it offers a 20-40% weight reduction compared to lead-acid equivalents while achieving over 2000 cycles at 80% Depth of Discharge (DoD). Its proprietary Management System (MD) ensures thermal stability, cell balancing, and overcharge protection.

How does capacity define 60Ah MD battery performance?
The 60Ah (60000mAh) capacity indicates energy storage potential—capable of delivering 60A for 1 hour or 6A for 10 hours. This C-rate flexibility supports both high-current automotive starts and sustained low-power loads. Pro Tip: Avoid continuous discharges above 1C (60A) to prevent premature capacity loss.
Three key factors optimize capacity utilization:
- Depth of Discharge: Limiting to 80% DoD extends cycle life by 3x compared to full discharges
- Temperature Management: Capacity drops 15% at -20°C but MD’s active balancing maintains ±2% cell variance
- Charging Efficiency: Accepts 0.5C (30A) charge current, reaching 90% SOC in 2 hours with CC-CV protocol
What voltage range does the 60Ah MD battery operate within?
Configured as a 20S lithium-ion pack, it delivers nominal 72V (67.2-84V working range). The MD system dynamically adjusts voltage output during peak loads, maintaining ±3% regulation under 100A surges. Comparatively:
| Parameter | 60Ah MD Lithium | Traditional Lead-Acid |
|---|---|---|
| Voltage Sag @ 60A | 2.1V | 4.8V |
| Recovery Time | <0.5s | 3-5s |
Real-world example: An electric scooter using this battery sustains 55km/h uphill (7% grade) where lead-acid models drop to 43km/h. Transitionally, the stable voltage profile also prevents controller reset triggers during acceleration spikes.
How does temperature affect MD battery operation?
The MD lithium battery maintains -20°C to 55°C operational range through:
- Ceramic-coated separators preventing dendrite growth below 0°C
- Active cooling channels dissipating 120W heat at 40°C ambient
In winter testing, cold cranking amps (CCA) remain at 760A even at -18°C—30% higher than AGM equivalents. However, charging below 5°C requires pre-heating via internal PTC elements to prevent lithium deposition.
| Condition | Capacity Retention | Cycle Life |
|---|---|---|
| 25°C Standard | 100% | 2000+ |
| 45°C Continuous | 89% after 500 cycles | 1500 |
What safety features are integrated?
Five-layer protection mechanisms ensure failsafe operation:
- Voltage-critical MOSFET cutoff (<2.5V or >4.25V/cell)
- Pressure-release vents activated at 150kPa
- Glass-fiber reinforced separators with 180°C melt point
- Ground-fault detection (2ms response)
- CAN-bus communication for BMS-health monitoring
During short-circuit tests, the MD system interrupts 500A faults within 15μs—7x faster than industry average. Practically speaking, this allows direct replacement in automotive applications without additional fuse requirements.

FAQs
Yes, but requires voltage-compatible alternator (max 14.8V) and programmed charge profile. Most modern vehicles need BMS communication integration.
What’s the typical lifespan in solar applications?
8-12 years with daily 50% DoD cycles. Ensure charge controllers limit absorption voltage to 82V (at 25°C).
Is parallel stacking supported?
Up to 4 units in parallel using MD-CAN bus synchronization. Never exceed 240Ah total without professional configuration.
