1DC HOUSEDC HOUSE 12V 400Ah Lithium LiFePO4 Deep Cycle Battery, Low Temp Cut Off, 5120Wh Energy Max. Built-in 200A BMS for RV, Solar, Home Energy Storage, Marine Trolling Motor, Boat, Golf Carts (2 Pack 200AH)
Main highlights- NOTE：Two batteries are shipped separately. If you receive one package only, please wait patiently for the other.
- Multi-application: LiFePo4 lithium battery is the most stable battery and it is perfect for energy stockage, outdoor applications , RV, golf carts, solar panels, or used as backup power supply, etc. It couldn't be used in a motor starter battery.
- Low Temp Cut-Off: DC HUSE 12V 200ah lifepo4 battery has upgraded Low Temperature Protection. When the temperature sensor of lifepo4 detects that the temperature is below 19.4℉, the BMS will cut off the charging function, cut off the discharge when it is below -4℉, and automatically recover after the temperature rises to 32℉. Effectively protect the 12V 200Ah battery and extend the battery life.
- High Energy Density: Lithium iron phosphate battery has high energy density, Long cycle life, Good safety performance, No memory effect, etc. LiFePO4 battery has built-in BMS protection to prevent overcharge, Over-discharge, Over-current, and short circuits, and excessively low self-discharge rate ensuring up to 1-year maintenance storage
- Capacity Expansion: The 12V 200AH lithium battery can be used not only in parallel connections but also in series. The 165Ah batteries can be safely connected in series and in parallel （4P2S/2S4P） for larger capacity (Max 800Ah ) or higher voltage (24V, 36V, 48V)，which will delivery an impressive 20.48KWh Energy.
- Attention and Service: DC HOUSE is committed to providing 3 years of reported service for every battery sold. If you need help, please get in touch with us through Amazon or the after-sales address in the manual. We will provide professional and complete advice on battery connection, charging, and discharging.
- 10 Years lifespan: DC HOUSE lithium iron phosphate battery (LiFePO4) can be recharged more than 4000 times in a deep cycle to achieve a longer cycle life. More than 8 times higher than lead-acid batteries (generally only 300-400 cycles can be charged).
