The YNX 48V 100Ah LiFePO4 Battery with BMS is a high-performance solution for tricycles, golf carts, solar storage, and inverters. Its lithium iron phosphate chemistry ensures 4,000+ cycles, thermal stability, and 95% depth of discharge. Integrated BMS protects against overcharge/overload, while the 10A charger enables full recharge in 10 hours. Weighing 45% less than lead-acid alternatives, it delivers consistent power in temperatures from -20°C to 60°C.

What Makes LiFePO4 Chemistry Superior for Deep-Cycle Applications?
LiFePO4 batteries outperform traditional lead-acid and other lithium variants through exceptional thermal stability (withstands 270°C before decomposition) and a flat discharge curve that maintains 12.8V/cell until 90% depletion. Their crystalline structure resists dendrite formation, enabling 4,000-7,000 cycles at 80% DoD compared to 300-500 cycles for AGM batteries. This makes them ideal for daily deep-cycle use in solar storage and electric vehicles.
How Does the Integrated BMS Enhance Battery Safety and Longevity?
The 48V battery management system monitors cell voltages (±0.05V accuracy), temperatures, and current flow. It actively balances cells during charging (up to 5A balancing current), prevents over-discharge below 10V system voltage, and limits charge current to 50A. The BMS communicates via CAN bus, providing real-time SOC/SOH data to inverters while enforcing thermal shutdown at 75°C±5°C.

The advanced balancing algorithm prioritizes cells with voltage deviations greater than 0.03V, redistributing energy at 2.5W per cell during charging cycles. This precision extends pack lifespan by preventing capacity drift – third-party testing shows less than 3% cell divergence after 1,000 cycles. The system’s 16-bit microcontroller samples data at 100ms intervals, enabling rapid response to short circuits (disconnect in <500μs) and ground faults.

Which Applications Benefit Most from This 48V Battery Configuration?
Optimized for 48V systems in golf carts (30-40km range per charge), solar arrays (4.8kWh storage capacity), and 1.5kW inverters. The IP54-rated casing withstands vibration (MIL-STD-810G) in mobility scooters and marine applications. Compatible with Victron/SMA charge controllers, it supports parallel connections up to 4 units (19.2kWh total) via proprietary daisy-chaining terminals.
What Charging Specifications Apply to the Included 10A Charger?
The UL-certified 10A smart charger uses 4-stage charging: bulk (56.8V), absorption (54V), float (53.6V), and equalization (58.4V monthly). Its CC/CV algorithm achieves 0-100% charge in 10 hours with ±1% voltage regulation. The charger auto-detects battery chemistry and includes desulfation mode for lead-acid backups, with thermal cutoffs at 65°C ambient temperature.
How Does Weight Reduction Impact Mobility System Performance?
At 28kg (vs 75kg for equivalent lead-acid), the battery reduces electric vehicle curb weight by 35-40%. This extends scooter range by 18-22% (per SAE J2983 testing) and lowers golf cart energy consumption to 0.25kWh/km. The compact dimensions (520x240x210mm) allow vertical or horizontal mounting in tight chassis spaces while maintaining 50% higher shock resistance than industry standards.
What Certifications Ensure Safety and Quality Compliance?
Certified to UN38.3 (transport), IEC 62619 (industrial use), and CE/ROHS standards. The UL 1973-compliant cells use flame-retardant electrolytes (auto-extinguishing within 30s per UL 94 V-0). The battery achieves 85dB noise immunity in EMI tests and 500VAC isolation resistance, meeting EMC Directive 2014/30/EU for vehicular integration.
Third-party validation through TÜV Rheinland confirmed 100% compliance with vibration standards after 8-hour sinusoidal testing at 30G acceleration. The battery’s cell-to-pack design eliminates 98% of intercell wiring, reducing potential failure points. All production batches undergo 72-hour formation cycling with capacity verification to ±1.5% accuracy before BMS installation.

Expert Views
“YNX’s 48V architecture bridges the gap between automotive-grade and stationary storage systems,” notes Dr. Elena Marquez, EV battery researcher. “Their use of ultrasonic-welded busbars eliminates 92% of connection failures seen in screw-terminal designs. The 0.5C continuous discharge rating (peaking at 1.5C for 30s) makes it uniquely suited for regenerative braking systems in next-gen mobility solutions.”
