The Power Queen brand launches its improved best-selling product: the 12V 140Ah lithium iron phosphate battery (H190). To meet customer suggestions, we have maintained the original size of the H190 (358 177 189 mm) with a weight of 12.7 kg. Based on the same size, you can choose a battery with a larger capacity to power more powerful devices and enjoy a better RV travel experience. Stable and Convenient Bluetooth Control? The 12V 140ah lithium iron phosphate battery has FCC Bluetooth certification. To test the stability of the link between the battery and Bluetooth, our batteries successfully passed the test and obtained the corresponding laboratory report, showing that the connection of our battery to Bluetooth is very stable. With Bluetooth, we can easily visualize and manipulate the battery on the phone, including viewing the SOC, the operating state of the battery, the remaining capacity, the battery temperature, etc. And we can turn off the battery directly from the phone. We upgraded the BMS from 100A to 150A. The 150A BMS board means you can drive a wide range of electrical loads, using a greater variety of devices. For example, our battery can power most coffee makers on the market for car use. The upgraded BMS is equipped with a self-recovery function, which automatically restores the battery after 30 seconds of overload, simplifying your operation. The BMS is equipped with a precharge function, meaning the battery can be compatible with all inverters without any additional cement resistance. Perfect for replacing AGM/GEL/Lead-Acid batteries? The Power Queen 12V 140Ah LiFePO4 battery weighs only 12.7KG, 42% of the weight of a 140Ah lead-acid battery at 29.8KG. Lower self-discharge rate of 3% per month compared to 15% per month for lead-acid batteries.

In addition, the Power Queen 12V 140Ah LiFePO4 battery has a lifespan of 10 years and cleaner, non-toxic, non-hazardous materials. Comparing with the old Bluetooth 12V 100ah h190 battery?

The Bluetooth 12V 140ah h190 battery has the same size as the old battery, but the capacity has been increased by 40%. The two batteries of different capacities can be expanded to 4 in parallel and 4 strings, 12v100ah - 4p4s-51.2v400ah, 12v140ah - 4p4s-51.2v560ah. Get more discounts when purchasing 4 packs.

Low Temperature Auto Cut-off Protection? The BMS board of the Power Queen 12V 140Ah H190 Bluetooth battery has added a low-temperature protection function, which automatically cuts off charging when the temperature is below 0°C (restarting charging at 5°C), and automatically cuts off discharging when the temperature is below -20°C to protect the battery and extend its lifespan. This battery is an energy storage battery rather than a starting battery; we do not recommend using it to start engines or golf carts. To activate the Bluetooth function, please power on the battery by charging it for 3 to 10 seconds with a LiFePO4 battery charger. The effective working distance of Bluetooth is 10 meters without obstacles. If the OT terminals are directly fixed with screws and their thickness is less than 2 mm, please add washers to ensure a secure attachment and avoid loosening or overheating. The same precaution applies when using clamps.
