The 72V 40Ah LiFePO4 battery with 24S BMS is engineered for high-power electric motorcycles (3000W-6000W), scooters, and balance cars. Its lithium iron phosphate chemistry ensures thermal stability, 2000+ cycles, and 40Ah capacity for extended range. The 24S BMS optimizes voltage balancing, temperature control, and overcurrent protection, making it safer and more efficient than lead-acid alternatives.
How Does the 24S BMS Enhance Battery Performance?
The 24-cell battery management system (BMS) monitors individual cell voltages, prevents overcharging/discharging below 2.5V, and balances energy distribution across all 72V. It enables real-time temperature tracking (operating range: -20°C to 60°C) and limits discharge currents to 100A continuous (200A peak), protecting against short circuits in 3000W-6000W motors.
What Safety Certifications Apply to LiFePO4 Batteries?
This battery meets UN38.3 (air transport), CE, and RoHS standards. The UL-certified BMS includes IP65 water resistance, flame-retardant ABS casing, and anti-vibration cell spacers. Unlike NMC batteries, LiFePO4 chemistry eliminates thermal runaway risks, maintaining stability even at 300°C.
Which Vehicles Are Compatible With This Battery?
Designed for 72V systems: 3000W-6000W electric motorcycles (e.g., Sur-Ron Light Bee), dual-motor scooters, and heavy-duty balance cars. Fits standard battery trays with M8 bolt terminals. Includes XT90 connectors and 15mm² cables for 150A continuous loads. Not compatible with 48V/60V systems without voltage converters.
Eve Energy Production Expansion
| Vehicle Type | Power Range | Connector Type |
|---|---|---|
| Electric Motorcycles | 3000W-6000W | XT90-S |
| Dual-Motor Scooters | 4000W-8000W | Anderson SB175 |
For custom installations, the modular design allows parallel connections using 6AWG cables. Off-road applications benefit from the shock-resistant casing that withstands 15G vibration loads. Urban delivery scooters achieve 120km range per charge when paired with 3000W hub motors.
How Does Temperature Affect Battery Efficiency?
LiFePO4 retains 85% capacity at -10°C vs 50% for lead-acid. At 45°C, self-discharge is 3%/month vs 30% for SLA. Built-in BMS activates heating pads below 0°C and cooling fans above 50°C. Optimal performance range: 15°C-35°C with ≤5% capacity fluctuation.
What Maintenance Extends Battery Lifespan?
Store at 50% charge if unused ≥3 months. Avoid full discharges – recharge when voltage drops to 60V (20% SOC). Balance cells every 50 cycles using BMS’s passive balancing (50mA current). Clean terminals quarterly with dielectric grease to prevent corrosion.
| Maintenance Task | Frequency | Tools Required |
|---|---|---|
| Terminal Cleaning | Every 3 Months | Wire brush, dielectric grease |
| Cell Balancing | Every 50 Cycles | BMS interface cable |
Deep cycle recovery requires a 72V balancing charger that applies 3.65V/cell. Storage in climate-controlled environments (10°C-25°C) reduces calendar aging by 40%. Users should avoid exposing terminals to saltwater, which accelerates corrosion rates by 8x compared to freshwater environments.
“The 24S configuration is revolutionary for high-torque applications. By splitting 72V into 24 cells, we reduce internal resistance by 40% compared to 16S layouts. This means cooler operation at 6000W loads and 92% energy efficiency – a game-changer for performance EVs.”
