12V 140AH Lifepo4 battery with Bluetooth and 150A BMS, suitable for outdoor

【Designed specifically for under RV seats & H190】Compared to the H190 lithium battery of the same size and height, it increases energy by 40%, measures 352 mm long x 174 mm wide x 190 mm high, and weighs only 1/3 of a lead-acid battery. Without compromising seat comfort, it reduces vehicle weight and space, making it ideal for storage under campervan seats for backup. 【A+ Home Safety Battery Cells】The 12V Lifepo4 Bluetooth Battery uses Grade A+ Home Safety Battery Cells, which improve energy density while enhancing safety, with a lifespan of up to 10 years, three times that of similar lead-acid batteries. It supports 15,000 cycles, making it a perfect replacement for lead-acid/gel/AGM batteries! 【Bluetooth App & Wide Range of Applications】Built-in Bluetooth 5.0, allowing you to view battery remaining power, voltage, current, battery temperature, differential voltage, cycle count, etc. in real time via a mobile app. The lithium 12V 140Ah is widely applicable to campervans, off-grid energy storage, outdoor camping, electric boat propulsion, backup power, and solar systems. 【150A BMS & Safe and Durable】Built-in 150A intelligent BMS to prevent battery overcharging, over-discharging, overload, high temperature, and short circuits. Low temperature protection: automatically stops charging when the temperature is below 0℃, automatically stops discharging when the temperature is below -20℃, and automatically resumes charging at 5℃. This effectively extends battery life and provides you with the highest level of safety. 【Green Energy & Supports 4S4P】The lithium battery 12V contains no heavy or rare metals and has a very stable internal chemical structure, ensuring it will not burn or explode even under impact or drop. It supports 4 series and 4 parallel expansion, allowing for a maximum capacity of 28.67kWh with 16 batteries, meeting the needs of high-demand energy storage scenarios! 【5-Year After-Sales Service】We provide 5 years of after-sales service and professional technical support. Our engineers will respond online within 12 hours.We recommend using a 14.6V (10A-50A) lithium battery charger.
