  • LED Display (Optional)

Build an LED display outside the product group to visualize the overall data and status of the battery pack. You can also DIY the operation functions of the display according to your needs.

  • Self-heated Function (Optional)
The BMS system can be set with a self-heating function to make the battery system suitable for lower temperatures. 
When the temperature is below 0°C, through self-heating, the temperature of the battery can rise to above 10°C within a few tens of seconds, thereby activating the normal application of the battery. 
Start heating temperature: ≤0℃. Stop heating temperature: ≥10℃.
  • Bluetooth Function (Optional)
Can communicate with BMS in wireless mode. Users can connect the battery pack via Bluetooth, which allows visualizing all-important battery information such as voltage, current, temperature, SOC, SOH, errors, etc. 
Some parameters and switch systems can also be controlled remotely, making everything easy to use and manage.
  • State of Health (Optional)
It can detect and reflect the battery capacity, health, and performance status with the accumulation of battery usage time and the impact of the environment, effectively guiding how to maintain the battery

Not only can we know whether the remaining available capacity of the battery can meet our demand for the total temporary power consumption, but also know when each single battery and battery pack needs to be replaced and repaired.

How many lithium batteries does it take to run a house?

Mainly depends on the total power consumption of the household. Assuming that the power consumption of all electrical equipment in a family is 10kwh a day, A 3.2V 200Ah battery can provide 0.64KWH power. Then a total of 10/0.64≈16 batteries are needed.
Contact us, choose battery specifications (100ah,161ah,172ah,200ah,228ah,300ah,345ah,400ah,456ah) according to different needs, and customize your wall mount battery capacity.

What is the lifespan of the wall mount lithium battery?

Harveypower wall battery for solar all has 20-year design life, a minimum of 6000 cycles is sufficient to provide one cycle per day for 16 years.
Good maintenance can further prolong its service life.
