How to prevent over-discharge of Tricycle With Cabin?

When the temperature is too low, it is necessary to shorten the use time of the Tricycle With Cabin as much as possible and charge it in time. Therefore, when riding an Tricycle With Cabin in winter, you must not leave the battery in a low-power state for a long time. You must develop a good habit of charging in time at night no matter how much you travel every day. At the same time, it is best not to leave the battery idle for a long time. If the Tricycle With Cabin is not used in winter, it is best to charge the battery every other month to ensure the storage capacity of the lead-acid battery and avoid acid spillage and damage to the battery.

After the battery is discharged to the end voltage, it continues to discharge, which is called over-discharge. Over-discharge will damage the battery, which is very detrimental to the electrical performance and cycle life of the battery. When the battery is discharged to the cut-off voltage, the internal resistance is relatively large, and the concentration of the electrolyte is very thin.
In particular, the inside and surface of the plate hole are almost neutral. During over-discharge, the internal resistance will tend to heat up and expand in volume. When the discharge current is relatively large, it will obviously heat up. At this time, the concentration of sulfur and lead is very high. The possibility of short-circuiting of the surviving crystal increases. Moreover, the sulfur lead will crystallize into larger particles at this time, that is, an irreversible sulfur salt will be formed, which will further increase the internal resistance and the charging recovery ability is very poor. There is no setting. The method to repair it is to prevent over-discharge when using the battery. Taking "under-voltage protection" is a very effective measure.
