WHY CHANGE FROM A LEAD-ACID BATTERY TO A LITHIUM BATTERY on golf cart

In response to this problem, we will make a comparative analysis from the following aspects:
1. CHARGING THE BATTERY
Lead-acid battery: This battery has a very low charging efficiency - only 75%! A lead-acid battery requires more energy to charge than it provides. The excess energy is used for gasification and internal acid mixing. This process heats the battery and evaporates the water inside, which results in the need to replenish the battery with distilled water.

Lead-acid charging has serious limitations and many critical points. The following are the most important:
* Fast or partial charging can destroy lead-acid batteries
* Long charging time: from 6 to 8 hours
* The charger does not collect complete information about the battery. It only checks the voltage, which is not enough. Changes in temperature can affect the charging curve, so if you don't measure the temperature, the battery will never be fully charged in winter and vaporize too much in summer。
* Incorrect charger or settings can shorten battery life
* Poor maintenance can also reduce battery life

Lithium-Ion Batteries: Lithium-ion batteries can be "fast" charged to 100% capacity.

2. WEIGHT OF BATTERY
In general, lithium batteries are 5 times lighter than lead-acid batteries of the same capacity

3. MAINTENANCE
Lead-acid batteries: High maintenance and system costs. Ordinary maintenance is one of the biggest costs because it includes adding water, maintaining the filling system, and removing oxide from components and terminals.

* Infrastructure costs: Lead-acid batteries release gas when they are charged, so they must be charged in a dedicated area. What is the cost of this space and can it be used for other purposes?
* Gas Disposal Charges: Gases released by lead-acid batteries must not remain in the charging area. It must be moved to the outside through a special ventilation system.
* Water desalination cost: In smaller companies this cost can be included in routine maintenance, but for medium to large companies it is a separate expense. Demineralization is a necessary treatment of water used to replenish lead-acid batteries.

Lithium-ion batteries: No infrastructure costs, no gas, no water, eliminating all extra costs. The battery just works.

4. LIFESPAN
The life of lithium batteries is generally 5 times that of lead-acid batteries.

5. SAFETY, WATERPROOFING AND EMISSIONS
Lead-acid batteries have no safety features, are not sealed, and release hydrogen gas when charged. In fact, their use in the food industry is not permitted (except for the "gel" version, which is less efficient).

Lithium batteries are emission free, suitable for all applications (IP67 also available) and have 3 different control systems to protect the batteries:
* Automatically disconnect, disconnect the battery when the machine/vehicle is idle to protect the battery from improper use by customers
* Balancing and management systems to maximize cell efficiency
* Remote control system with automatic warning of failure and failure
