Why don't the battery recommended depth discharge?

Source: 2020 - 03 - 30 14:04 hits: although both are deep discharge, but they are not the same concept. 1, normal circulation of the deep discharge, it is repeated. It is our usual habit of electricity, if every time charging excessive, cell differentiation occurs within the material, the cells in a very unstable state, so it will seriously affect the service life of the cell. 2. Capacity recovery depth discharge are rare. Recycling depth charge and discharge capacity, it takes a certain cycle, through the depth of the charge and discharge, the end part of the lithium ion due to the high rate of failure to participate in response to form the capacity of the decline. Usually, in a certain period after it is done. 1 KWH is equal to 1 KWH this idea is that you can drive a kw load for one hour. A typical 18650 battery capacity is about 2000 mah ah voltage 3 = 2. 7 v material 4 v4v times 2 ah is 8 wh that's an hour 8 tile load. So, 1000 wh÷ 8 wh = 125。 That is to say, you need at least 1252000 18650 mah battery capacity to provide 1 KWH of electricity. 2. 2 KWH = 2200 wh, wh, 2200 8 now wh = 275. That is to say, need at least 275 2000 mah battery to provide 18650 2. 2 KWH of power.
