WHAT OUR PARTNERS SAY

FAQ – Battery Solutions for Medical​ Applications

Lithium batteries, especially LiFePO4 chemistry, offer 2–3 times longer lifespan, higher energy density, faster charging, and lower maintenance compared to lead-acid. For infrastructure systems such as traffic signals and telecom towers, this means reduced downtime, fewer replacements, and lower total cost of ownership (TCO).
Yes. Our battery packs are designed to work seamlessly with hybrid systems, supporting grid power, solar PV, or both. With intelligent BMS, the system automatically manages input sources, ensuring uninterrupted operation of infrastructure equipment.
Our infrastructure battery solutions are engineered with IP65–IP67-rated enclosures, anti-corrosion coating, and wide operating temperature ranges (−20 °C to +65 °C). They are proven to withstand rain, dust, vibration, and extreme heat or cold, ensuring long-term reliability.
Absolutely. All packs are certified according to UN38.3, IEC62133, CE, and RoHS, with optional industry-specific standards (EN50155 for rail, ATEX for hazardous areas). This ensures safe global transportation, installation, and deployment.
Backup runtime depends on system configuration and load. For example, a 48 V 100 Ah pack can support a telecom tower for 8–12 hours, while modular street lighting batteries can power 2–3 nights of illumination. Systems are scalable, so runtime can be extended as needed.
Yes. Our smart BMS supports CAN, RS485, or IoT protocols (LoRa/NB-IoT), enabling operators to remotely monitor state of charge (SOC), state of health (SOH), temperature, and alarms. This reduces site visits and maintenance costs, which is critical for distributed infrastructure networks.
