Essential for families: car boot power

Have you encountered these problems before?

1. Traveling outside, a few months did not use the car, came back and found no battery car can not start, go to the repair shop there is no ignition 300.

2. go out to travel, halfway car can not start, before the village, after the shop, the kind of helpless, one can imagine!

3. Yesterday forgot to turn off the lights, battery exhausted, and today rush to receive customers, but the car can not start, people headache!

Basically, every car will encounter when the battery is dead. So the question is, is it called car repair, trailer, or direct use of car to start the power?

Car boot power is another kind of mobile power, then what is the difference between it and ordinary mobile power?

Batteries are different, ordinary mobile power is 18650 or soft pack battery, charge and discharge rates are small, the general operating current at 1C (the battery capacity to double the current value of charge and discharge), work an hour. When the car starts often reach 100A or hundreds of security, work a few seconds. Different application environment, then the requirements of the batteries are also different. Car boot power, using a high rate discharge batteries, the general use of 30C or 40C batteries to use, of course, the price of the batteries are more expensive than the average.

There are two types of cars, 12V for gasoline cars and 24V for diesel cars. Ordinary mobile power is used in parallel to increase the capacity, start power is to increase the voltage in series. The same capacity of the power supply, the power will be used to start several times the batteries.
