What else can I help you with?
How do you link 2 12V car batteries in parallel to keep 12v but increase the amps?
You just connect negative to negative and positive to positive. Click the link for a diagram.
You want to take 25ams output you are having 16 Nos of 12V 8Ah batteries do you have to connect batteries in series of parallel connection?
Parallel or Series Connections for BatteriesTo increase current [measured in Amperes], you connect batteries in parallel. To increase voltage, you connect batteries in series.
Can you put THREE 12v batterys in series?
Sure you can and you will end up with 36 volts. Connect them in Parallel and you will have 12 volts.
What voltage will you get adding 2 solar panels of 18V 3 amp and 12V 3 amp if you connect them parallel should you get 6 amp not sure on voltage though does it drop to 12v?
yes, it is 12 volts
Can a diagram for two 12V deep cycle motor home batteries connected to output 12V be supplied?
You just connect them in Parallel. Two 12 volt batteries connected in parallel will output 12 volts. Two connected in Series will output 24 volts. Just connect the negative terminal on the first battery to the negative on the second battery. Then connect the positive terminal on first battery to the positive on the second battery. Connect the cables to the second battery, positive to positive and negative to negative. Click the link for a diagram.
I WANTED TO USE SINGLE 5MM LEDS TO MAKE A LIGHT BAR FOR A VEHICLE HOW CAN I MAKE A 55 WATT LIGHT BAR RUN OFF 12V BATTERY?
Connect it from the battery to a switch running through a 10 amp fuse.
Trying to make some indicators for a bike and am going to use 1.5 volt leds and a 12 volt 11ah battery by putting 8 leds in series was wondering whether resistors are needed not to short the leds?
Resistors will be needed in all cases when driving LEDs from a voltage source, unless you are using LEDs that already have a built in current limiting IC inside the package (a few do these days, for example I have some blinking LEDs that need no resistor they have a blinker IC built in that also limits current).However you have another problem that you obviously are not aware of. 8 LEDs rated at 1.5V in series totals exactly 12V. But your battery is only rated at 12V. As the battery discharges its voltage slowly drops, the moment it drops under 12V all the LEDs will turn off! I strongly recommend that you use no more than 7 LEDs rated at 1.5V in a circuit powered by a 12V battery, so that the battery can actually gets a chance to discharge beyond its knee voltage. In this case the resistor will drop the remaining voltage, whatever it is depending on the charge state of your battery.
If Four 12 voltsbatteries connected in parallel and one 12 volt battery in series how much voltage is active across circuit?
A == B (- 12V +) (- 12V +) (- 12V +) A single 12V battery in series with 4x 12V batteries connected in parallel... Total voltage from A to B is 24 volts! Note that the single battery in series will limit the total current capacity to that of a single battery.
What are the best ways to power 12V DC LED lights efficiently and safely?
The best ways to power 12V DC LED lights efficiently and safely are to use a dedicated LED driver designed for 12V DC LEDs, ensure the driver has the correct wattage and voltage ratings for the lights, and properly connect the driver to a stable power source with the correct polarity. Additionally, using high-quality wiring and connectors can help maintain efficiency and safety.
Connect a 12v wire to an amplifier?
Ensure the amplifier is turned off. Connect the positive (+) terminal of the 12V wire to the amplifier's positive terminal and the negative (-) terminal of the 12V wire to the amplifier's negative terminal. Once connected securely, you can then power on the amplifier.
Can I connect 12 volts headlight to my 60 volts electric bike?
If the bike uses 5 12V DC batteries connected in series to achieve 60V DC you can connect the positive and negative wires from the 12V light ONLY to the first 12V battery in that series. The bike will remain 60V and the lights will be powered by the first 12V battery. If you connect the 12V light directly to 60V the light will blow instantly. Test the voltage with a volt meter before making any connections.
Can you charge batteries in series with 2 separate chargers in parallel?
Not in parallel NO - unless each charger is twice the voltage required for a single battery. For example if you had 2 x 12V batteries and placed the in series, you would have a 24V battery. If you had two 12v chargers and put then in PARALLEL with each other, you would then have a 12v charger with double the current handling. Of course if the chargers were 24v ones, then it would work fine. if you have 2 x 12v batteries (for example) and wished to charge them with separate chargers (actually quite a good idea), then each charger would be over each battery. So the batteries would be in series, the chargers would also effectively be in series too. Basically another way of looking at it would be two have a 12v battery with a 12v charger to your left and then on the right another 12v battery with a 12v charger on it. Yes you can connect the two together in series. The only slight caveat is that the chargers must be isolated from each other - and not for example a "dual output charger" which simply has an extra pair of leads but a shared charging system. - 12v + - 12v + ---------+-BATTERY---+----------+--BATTERY--+-------- - | |+ - | | + |=CHARGER=| |=CHARGER=| - <------------------------------- 24 v ----------------------------> +
