Description

BYD Cells & UL 1973 Tested: Power your system with premium BYD LiFePO4 cells, outperforming many lithium-ion products on the market. Officially tested to UL 1973 safety standards, it is built with a high-performance 100A BMS for comprehensive protection and reliable operation. The system safeguards against overcharging, over-discharging, overload, and short circuits, while low-temp cutoff and overheat protection ensure adaptability to extreme weather and emergency outages. It also provides dual safety guarantees: power forced off/on and an air switch for auto-shut off on overload.
3A Active Balancing & Durability Structure: A maximum balancing current of 3A, combined with fast multi-channel equalization, improves efficiency, reduces energy loss, and extends battery life. It features premium core components housed within a robust internal metal structure, all encased in a high-quality, fireproof, and wear-resistant sheet metal casing that offers excellent heat dissipation.
Powerful Capacity & Output: The server rack battery's impressive capacity of 5120Wh and output power of 5120W supports the use of high-power appliances for extended periods. It supports automatic addressing with a maximum of 20 parallel connections (102.4kWh) and automatic host-slave identification. Additionally, it achieves rapid 1C charging from multiple sources, including solar and generators. It is perfectly suited for a wide range of applications, including Home Storage Emergency, Off-Grid, Industrial, Commerical, and UPS.
Smart Usage: Equipped with a mobile app for quick connection and remote monitoring of single or multiple battery statuses (voltage, current, capacity), it supports CAN/RS232/RS485 communication protocols for seamless compatibility with all-in-one inverter chargers, and features a built-in indicator for convenient local status checks.
Space-Saving 3U Rack Design & Massive Scalability: This 48v lithium battery features a compact, lightweight 3U server rack design (17.32" x 19.69" x 5.24", weight: 96.45 lbs), offering easy installation and facilitating the use of multiple batteries. Compared to four 12V 100Ah lead-acid batteries, it is 60% lighter and 33% smaller. This 48V 100Ah lifepo4 battery also supports massive scalability through vertical stacking, automatic addressing for a maximum of 20 parallel connections, and automatic host-slave identification, allowing you to build a substantial 102.4kWh energy storage system to meet growing power demands.

Humisenk paired with a Pecron, its bliss

I paired this big boy with a Pecron FP3000LFP and I couldn't be happier. Im sure I will buy another Humsienk to add to the stack. I'm using the pair to power my gas furnace and the electrical part of my On demand gas water heater. I'm ready for any power outage. FYI, I will upgrade cables to 4G

UL listed vs UL tested

The main description says this batter is UL1973 Listed. That means the unit can be used for permitted home use. My research suggests the cells within the unit have been UL1973 tested, but the entire unit is NOT UL1973 Listed, thus can not be used for permitted home use. Please clarify.
