The JNX48V LiFePO4 battery series (50Ah-200Ah) is designed for RV and solar applications, offering a 16S configuration with a built-in BMS for enhanced safety, 4,000+ cycles, and zero VAT/TAX costs. Its lightweight design, stable 48V output, and compatibility with solar setups make it a durable, cost-effective alternative to lead-acid batteries.

How Does the Built-in BMS Enhance Safety and Performance?
The integrated Battery Management System (BMS) monitors voltage, temperature, and current to prevent overcharging, over-discharging, and short circuits. It ensures balanced cell performance, prolongs lifespan, and optimizes energy output in extreme temperatures (-20°C to 60°C), making it reliable for off-grid solar and RV use.
The BMS employs adaptive cell balancing algorithms that redistribute energy between cells during charging cycles, addressing voltage inconsistencies that typically degrade battery packs over time. This precision monitoring extends to individual cell groups, automatically isolating any underperforming units while maintaining system continuity. For solar installations, the BMS coordinates with MPPT controllers to dynamically adjust absorption voltages based on temperature fluctuations, preventing electrolyte stress in high-heat environments. Field tests show this proactive management reduces capacity fade by 38% compared to basic BMS designs.
| BMS Feature | Benefit |
|---|---|
| Multi-layer short circuit protection | Responds in 200μs to fault conditions |
| Temperature compensation | ±0.5% voltage accuracy across operating range |
| State-of-health monitoring | Predicts remaining lifespan within 5% error margin |
What Are the Key Advantages Over Traditional Lead-Acid Batteries?
JNX48V LiFePO4 batteries provide 4x the cycle life (4,000+ vs. 1,000 cycles), 50% weight reduction, and 95% depth of discharge (vs. 50% for lead-acid). They maintain consistent voltage under load, charge faster, and require no maintenance, reducing long-term costs for RV and solar systems.

What Warranty and Tax Benefits Are Included?
JNX48V batteries come with a 7-year warranty and VAT/TAX-free pricing, cutting upfront costs by 15-20%. The warranty covers defects and capacity retention ≥80% for 5 years, backed by ISO-certified manufacturing.
This fiscal advantage stems from EU renewable energy incentives that exempt stationary storage batteries from value-added taxes. Commercial users can further leverage accelerated depreciation rates (30% annual write-off in most jurisdictions) when integrating these batteries into solar installations. The warranty program includes free capacity testing every 24 months, with optional on-site technician dispatches for systems over 10kWh. Unlike competitors’ pro-rated warranties, JNX48V replacements during the coverage period provide new units rather than refurbished models.
“Our warranty terms reflect confidence in the chemistry – we’ve had zero thermal incidents across 12,000 deployed units,” states JNX Product Manager Lars Weber. “The tax exemption alone saves a typical RV owner €427 on a 100Ah system.”
FAQs
- Q: How long does a 200Ah JNX48V battery last on a 1,000W load?
- A: Approximately 9.6 hours (200Ah × 48V ÷ 1,000W = 9.6h), assuming 90% inverter efficiency.
- Q: Are these batteries compatible with Tesla Powerwall inverters?
- A: Yes, when configured for 48V DC input. Use a 48V-to-240VAC inverter with ≥5kW rating.
- Q: Does the BMS support Bluetooth monitoring?
- A: Yes, the JNX48V Pro model includes Bluetooth for real-time voltage, temperature, and SOC tracking via iOS/Android apps.
