Choose the right car lithium battery charger

Before preparing to buy a car lithium battery charger, many users tend to overlook important issues:

Everyone may think that the lithium battery has a large capacity, and it is necessary to choose a charger with a larger current to shorten the charging time. This belief is correct if you choose a home charger, but you cannot choose a car charger. Car chargers are different from household chargers. The power source of car chargers is the car's generator, so before buying a car charger, you must first understand the current of the car's generator. The maximum current of generators in 90% of passenger cars on the market is about 100A-120A. Choose a suitable charger according to the following formula.

100A×80%×60%＞Maximum charger input current (80% is the safe working current of the generator, 60% is the current required by the vehicle)

For example: 100A×0.8×0.6=48A ＞ TELUN charger input current is about 40A

According to the formula: 100A or 120A car generator should choose the car charger to input current about 40A.

Wrong choice of super current charger will shorten the life of the car's generator.
