- Why You Need It? – Protects your valuable LiFePO4 battery pack from overcharge, over-discharge, overheating, and overcurrent while ensuring balanced cell performance—maximizing safety, lifespan, and reliability for your entire power system.
- Designed for 4S LiFePO4 Batteries – Built specifically for 4-cell (12.8V nominal) LiFePO4 packs with a maximum charging voltage of 14.7V, ideal for solar storage, e-bikes, UPS, and portable power solutions.
- Robust 40A Continuous Current – Handles 40A charge/discharge current, with 120A peak overcurrent protection and fast 150ms delay—ensuring reliable high-load performance for demanding applications.
- Advanced Safety with NTC Sensors – Integrated NTC temperature sensors deliver intelligent thermal protection: charging cutoff at 50°C ±5°C, discharge cutoff at 70°C ±5°C, and automatic recovery to prevent overheating.
- Active Cell Balancing – Enhances battery health with 50mA balance current at a precise 3.575V level, keeping all cells aligned and extending overall pack life.
- Ultra Low Standby Power – Consumes just 40µA in idle mode and built with 30mΩ internal resistance, making it energy-efficient and ideal for long-term standby applications.
- Warranty:-The products come with 1 year warranty (To claim warranty feel free to contact amicikart at 980 970 9898 or care@amicikart.com).
The amiciSolar XJ-D096 4S 12V 40A BMS is a high-performance Battery Management System designed to safeguard and optimize LiFePO4 (LFP) battery packs. Perfect for 12.8V configurations, this smart BMS offers robust 40A current handling, precise overcharge and over-discharge protections, and 120A peak overcurrent cutoff to protect both batteries and connected loads.
Built for intelligent energy management, the XJ-D096 features NTC temperature sensing, cutting off charging at 50°C and discharging at 70°C, ensuring thermal safety in high-load or ambient heat environments. It balances cells with 50mA active current, maintaining tight voltage alignment across cells for maximum pack life.
Designed with low-power standby and 30mΩ internal resistance, this BMS is ideal for solar systems, electric bikes, power walls, backup energy packs, and other 12V battery-based applications where precision, protection, and performance matter most.
