Each block is 12V. When installed on the car, it is connected in series, that is, the positive pole of the first part is connected to the electric car and the negative pole of the first part (usually a black output connector) is connected to the positive pole of the next part (usually the red output connector), the negative electrode of the second block is connected to the positive electrode of the third block , the negative electrode of the third block is connected. connected to the positive electrode of the fourth block, and the negative electrode of the fourth block is connected to the electric vehicle.
This is usually equipped with wires. If you are replacing a lithium battery, you can directly connect the positive and negative poles of the battery discharge to the electric vehicle.

Electric vehicle battery maintenance:
Do atPay attention to heat dissipation when charging. Never charge in the sun in summer. All electric vehicle batteries need to be charged frequently. It is best not to charge for too long and never exceed twelve hours. The external depth of discharge will have a significant impact. over the lifespan. The relationship is the amount of energy left in your battery, which is also why you charge it frequently.
It is strictly forbidden for the battery to be exhausted when stored. Exhausted battery status means the battery is not charged in time after use. When batteries are stored in a depleted state, sulfation is likely to occur. Lead sulfate crystals adhere to the plates, blocking the ion channels, leading to insufficient charge and reduced battery capacity. The longer the inactivity time, the more damage tothe battery will be serious. Therefore, when the battery is not in use, it should be recharged once a month.
