4 2 volt headlamps with 8 4 volts will burn out?

The headlamp is used in, and it will definitely burn out, because the voltage exceeds the rated voltage range of the headlamp too much, and it is recommended to use the rated voltage of the headlamp to supply the power.

The voltage of the volt lamp head is a serious overvoltage, which will definitely cause the lamp head to burn out.

Volt headlights are not allowed to be volt, so it will be burned out, this is absolutely not allowed.

If you use it for a long time, it is very likely to burn out the board, and it is best to use the headlamp in the voltage fluctuation up and down, and use the headlamp in one service or so, which is relatively safe and can ensure the normal use of the headlamp.

This one is definitely going to burn out, and you have two solutions:

1. Use the standard lamp head instead.

2. Use the two lamp heads in series.

Method 2 is not recommended

Hope it helps, thank you!

In electrical appliances, the lamp head is the lamp head; A light bulb is a light bulb, and a light head is a light holder where the light bulb is installed, and a light head and a light bulb are two different things. If the light is a lamp head, then this low-voltage head is no problem to use in the range of 0-10 volts, if you are referring to the bulb it is a different matter.

Will burn. It can be used in series with two volts of the same specification wattage.

The headlamp should be burned out, because the current and voltage are too large, so it may be burned out.

The volt headlamp will definitely burn out if it is used on the volt.

It's just that ordinary small bulbs (incandescent bulbs, like the small electric beads in the flashlight before) are OK, slightly brighter than the time, but the life will be slightly shortened, but many people regard LED as (or called) bulbs, so it can't be simply connected directly, and it needs to be analyzed and analyzed accordingly for specific problems.

The battery that cannot be charged should be charged with a charger of at least 9V

The 12V black silk glowing incandescent lamp beads are available for batteries, but the glow is darker. LED lamp beads are not good, they are not bright at all.

No. Your lamp beads are not working properly to glow.

Answer: Yes, in principle, it does not match.

As seen in Senshuqiang power supply information, the specifications of chargers of different models may be different, such as the current output of the charger is different. The standard charging current of the charger can ensure better charging efficiency, for example, the charging current of the charger is small, the charging time will be extended or the charging cannot be charged, if it exceeds the maximum, it may break down the electronic components. If the voltage and current of the two chargers are the same, it is fine.

1 All your equipment A 2 volt 1 watt battery in series = 8 volts 4 watts, (I don't know if the no-load voltage of a 2 volt 1 watt battery is 2 volts or the rated voltage is 2 volts). 2. A 6-volt electric fan.

3. One volt 1 ampere-hour lithium battery. 4. A charger? (One input 4-8V, 500mA, output lithium battery).

The correct connection method is: connect the output end of the solar cell 8 volts to the input end of the charger, install the volt lithium battery on the charger, and connect the output end of the charger volt to the electric fan.

The 12-volt charger should not be used with a point volt lamp, and the voltage on it is too high, which will burn out the bulb directly.

If you must use it, you can transform it yourself. Measure the resistance of your bulb first, and then connect a 5W resistor in series, which is two to three times the resistance of his. Quite a light bulb, the partial voltage allows the bulb to withstand only volt voltage.

No, the voltage is inconsistent. Mobile phone chargers are generally about volts, and your volt voltage headlamp cannot be charged with a mobile phone charger, so it is best to buy an appropriate charger to charge, otherwise it is easy to damage the headlamp.

No, the phone charger has a 5 volt output and cannot charge the volts.

I feel that what I said upstairs is not very reliable, if it is a battery of the same nature, then there is no big difference in voltage. However, the voltage of the battery is usually not different (most products are formed by different battery capacities to form different models), if the voltage is not the same, it is likely that the nature of the battery is different, so it is often not universal.

Charging the lamp doesn't need to be so fine, it can be used to charge, rest assured, no problem.
