Generally speaking, the lifepo4 battery will be equipped with a BMS protection board, and the cigarette lighter port will also be equipped with a fuse. Note that the load power will not trigger BMS protection, generally there will be no problem. However, it should be noted that the cigarette...
If you reach a certain number, there are many Chinese suppliers willing to turn the stud for you. Otherwise you can look for suppliers who have turned studs in stock.
This is due to the excessive unbalanced voltage difference in the internal resistance of each 12V battery. It may be better to fully charge each battery and let it rest for a while before connecting the battery packs in series.
Suppose you need 35KWh of electricity every day, a 48V 100Ah lifepo4 battery can store up to 5.12KWh, then you will need 35/5.12=7pcs. A 48V 150Ah lifepo4 battery can store up to 7.68KWh, then you will need 35/7.68=5pcs. This is just a rough estimate, in reality you may need more batteries.
Generally speaking, a multimeter has an option to measure internal resistance, or a special battery internal resistance meter can be used to measure it.
We just don’t recommend that lifepo4 batteries be stored at 100% capacity when not in use for a long period of time. It's fine if you use it occasionally. The lifepo4 battery comes with a BMS, but please note that the power supply should be cut off when the battery is not in use.
We guarantee that we use lifepo4 battery cells, and we have a 5-year warranties. The reason our batteries are lighter is because we have specially customized the corresponding casing for the 150Ah battery cell.
