1. Увод
This manual provides detailed instructions for the safe and efficient use of your DC HOUSE 12V 50Ah 2.0 Trolling Motor LiFePO4 Battery. Please read thoroughly before operation to ensure proper usage and longevity of your product.
2. Кључне карактеристике
- Trolling Motor Exclusive Battery: 12V 50Ah 2.0 trolling LiFePO4 battery equipped with 2 output ports: DC and Type-C, supporting charging for mobile phones, computers, drones, cameras, car refrigerators, and a series of DC equipment charging. This 50Ah LiFePO4 battery is ideal for trolling motors, marine applications, outdoor camping, RVs, and golf carts. The fixed-hole design prevents battery drops and shocks caused by outdoor bumps.
- SOC Status Indicator: The upgraded 2.0 12V 50Ah trolling motor LiFePO4 battery features visual LED indicators for easy real-time monitoring. It displays the LiFePO4 battery’s remaining SOC level, high and low temperature warnings, short circuit, overvoltagе, ундерволtage, BMS fault, and charging status. It also includes a one-button activation switch for convenient operation.
- Maximum Continuous Discharge 1.5C: Compared with other lithium batteries with a 1C discharge rate, the DC HOUSE 12V 50Ah 2.0 LiFePO4 battery offers a 1.5C discharge rate with a maximum continuous discharge current of 75A, providing higher efficiency and supporting more demanding loads. With 640Wh of energy, it delivers reliable and long-lasting power. Compared to traditional lead-acid batteries, this 12V 50Ah marine LiFePO4 battery offers a greater Depth of Discharge (DOD), allowing an 80W load to run continuously for 8 hours.
- Bluetooth APP Monitoring: The DC HOUSE 12V 50AH 2.0 LiFePO4 lithium battery has built-in Bluetooth, which can connect with the DC HOUSE APP (Bluetooth signal range 5-10 meters). It is convenient to monitor battery information such as SOC, voltage, current, etc., and the data is accurate to the specific cell of a battery. There is a special fault display page to help troubleshoot.
- Low Temp Cut-Off: The DC HOUSE 12V 50Ah 2.0 LiFePO4 battery has upgraded Low Temperature Cut-Off Protection. When the temperature sensor of the 50Ah lithium battery detects that the temperature is below 20℉, the BMS will cut off the charging function. It will cut off the discharge when it is below -4℉, and automatically recover after the temperature rises to 32℉. This effectively protects the battery and extends its life.
- Лагани дизајн: The 12V 50Ah 2.0 LiFePO4 battery features a lightweight design, weighing only 13.23 lbs—just 26% of the weight of a typical 12V 50Ah lead-acid battery (around 50 lbs). This makes it easy to use outdoors and allows installation in places where lead-acid batteries cannot fit. It is compatible with most battery boxes on the market, saving valuable installation space.
