Why Choose Our Battery?
Advanced LiFePO4 Chemistry
Our battery utilizes cells based on the lithium iron phosphate technology. The lithium iron phosphate technology has many advantages - the materials used in batteries are safe and the batteries are characterised by exceptional thermal stability. Furthermore, LiFePO4 technology is characterised by the flat discharge curve, compared to lead-acid and other lithium batteries.
Smart Battery Management System (BMS)
The battery is equipped with an automated Battery Management System (BMS). The BMS measures such parameters of the cells as the voltage, temperature, and current. The BMS is responsible for ensuring the correct charging and discharging process with the help of balancing the cells while using maximum capacity of the battery.
Dual‑Mode Communication & Remote Monitoring
By using the RS232, RS485, and CAN ports, the battery can be connected to many of the well-known inverters (like Victron, Growatt, GoodWe, SMA, etc.) and energy management systems. By using the combination of an integrated Bluetooth & Wi-Fi module and the APP we offer, the battery will provide all information on your mobile phone regarding SOC, charge/discharge current, temperature, and historical data on the battery. You can also upgrade the firmware easily.
High Discharge Current & Scalability
This battery can handle the continuous charges/discharges with current up to 120 A. Being parallelable, the battery can be used together with other batteries to increase the total capacity for bigger energy needs.
Robust Environmental Adaptability
Designed to operate from ‑20°C to +60°C and at altitudes up to 4000m, this battery performs reliably in diverse climates – from cold mountain regions to hot tropical areas. Its IP20 rating (indoor use) and corrosion‑resistant casing ensure durability in humid environments.
Easy Installation & Maintenance
The wall‑mounting bracket and pre‑drilled holes simplify installation. The touch screen and APP provide clear guidance for initial setup, parameter configuration, and fault diagnosis. No special tools or complex programming are required.
Energy Saving & Green
With over 8000 cycles, this battery reduces replacement frequency and lifetime cost. It supports solar/wind energy storage, helping you maximise self‑consumption of renewable energy and reduce your carbon footprint.
Application Areas
Our battery is 51.2v 100ah wall mounted battery on, widely used in:
Solar / Wind Energy Storage Systems – Store excess renewable energy for night‑time or cloudy days. Recommended solar panel power >1000W ensures efficient daily charging (with >6h sunshine).
Communication Equipment – Provides stable backup power for telecom base stations, repeaters, and data centres.
Emergency Power Systems – Critical power for hospitals, fire safety, and security systems during grid outages.
UPS Backup Power – Protects servers, network devices, and sensitive electronic equipment from voltage sags and blackouts.
Medical Equipment – Reliable backup for life‑support devices, diagnostic machines, and mobile clinics.
Fire and Security Systems – Ensures uninterrupted operation of alarms, access control, and surveillance cameras.
Off‑grid & Remote Areas – Ideal for cabins, farms, and remote monitoring stations where grid access is limited.
Its high discharge current and fast response make it suitable for both steady‑load and high‑surge applications.
Frequently Asked Questions (FAQ)
Q: Can I connect multiple batteries in parallel?
Yes, you can connect up to 15 units of the 51.2V100AH‑LS in parallel to increase total capacity. The built‑in BMS supports automatic address assignment and load sharing. Please refer to the manual for proper wiring and configuration.
Q: What inverters are compatible?
The included battery has RS232, RS485, and CAN capabilities that enable its compatibility with the most significant inverter brands (including Victron, Growatt, SMA, GoodWe, DEYE, Luxpower, and so on). However, if an inverter lacks communication, the voltage‑based charging/discharging method can still be applied.
Q: How long does it take to fully charge?
With a charging current of 120A, a fully discharged battery can be charged in 0.8‑1 hour under ideal conditions. But we suggest using a lower charge rate of 50 to 80A for a longer cycle life. Additionally, charging will depend on how much energy is output by the solar panel.
Q: What does "cycle life 8000" mean?
This means that the battery is capable of being charged and discharged for 8000 times, preserving at least 80% of capacity for the entire period (when discharged at 80%, at 25 Celsius). This ensures more than ten years of everyday usage.
Q: How do I monitor the battery remotely?
Download our free APP on App Store or Google Play. Enable Bluetooth or Wi‑Fi on your smartphone and pair it with the battery. Then, you will get access to real-time data and notifications.
Q: What protection features are included?
The BMS offers wide-ranging protection services including over-current, over-voltage, reverse-polarity, under-voltage, under-temperature, over-temperature, and short-circuit protection. The battery discontinues its output automatically under fault conditions, and resumes normal operations after rectification of the fault condition.
Q: Do you provide customised solutions?
Yes, OEM and ODM services are available for the battery. Please reach out to our sales team with the required voltage, capacity, connector, and labeling specifications.
