Why would I need 48v? What’s is the practical application? A long distance
from the battery to the load?

Now I understand. I can just connect 4 of these batteries in parallel and
power up my laptop. The old battery is worn out.

Danger, danger, danger. You DO NOT CONNECT batteries, or any voltage
sources, in parallel, without having diode isolation for each source. This
is because the voltage difference between the batteries (however small),
coupled with the very low internal resistance of the batteries, can cause
large current flows between the batteries.

Christ I just wanted to wire two 9V Batteries and I didn’t understand shit.

I’d like like if rockstar would allow tou to wear gloves with anything u
want nd also a MC DLC where u get some new motorcycles like the ones from
SOA nd even a leather MC vest that is some wat premade like it will say San
andreas in the lower back and then when u pick the vest to wear than ur
logo will go in the center of the back nd than ur crew name will go in in
the banner at the top of the back nd holsters for hand guns with different
types of holsters like hip, leg, back, shoulder holsters would be pretty
cool

my batteries drain in minutes running a single 5 watt bulb any help to why

Lots of confusion below. Although there is a saying, volts dont kill, amps
do, that is only partially true. The reason he is able to touch the two
terminals without a shock is because the voltage is too low to overcome the
resistance of the body enough to complete the circuit. If he had wet hands,
he would have felt it… and we would have known it. Basically, don’t try
it at home.
As you put more and more in series you are making it more and more
dangerous. A single battery has enough amps to kill you, but the higher the
voltage, the more likely you are to be shocked via your bare hands, or
through insulated handles/gloves.
The amps do kill you, but the higher the voltage, the easier it is for it
to bite you.
Converting to AC makes it even worse, because how the current alternates,
shocking you in short bursts over and over again, typically around 50-60
times a second. Sure fire way to kill a heart.

Great video, extremely easy to follow.

Stick some Auto fuses between batteries and again between arrays and again
on the final output cable/s based on the amount of current you are likely
to be drawing for whatever project / equipment you’re going to be powering
up. This way, if a battery suddenly decides to go internal short circuit or
perhaps something conductive like a spanner falls across some terminals, it
will help to reduce the damage and risk of fire and/or explosion as the
connecting cables and/or batteries get very, very hot very, very quickly
… I have 15A fuses between my 4 x 12v 20Ah pB batteries … if one cell
shorts, it will blow a fuse and won’t then try to draw 1,000+ amps through
the 30A or 40A jumper cables all at once ;)

Hi,I’m sorry I didn’t get back to you sooner,we went camping in Maine.I
plugged the fridge into a killawatt,on startup it uses .93 amp and 83
watts.The marine battery has 675 marine cranking amps,105 amps,and 182
minutes reserve capacity.On the frig the only reference to amps is 1.4
amp input current.Thank you MrDavey,this will be a great help to my
family.Rob

for best results use a 120 volt dc battery bank connected to a 120volt DC
to 120 volt AC inverter

If I connect few batteries in Series does the output increase as well? For
instance if I connect bunch of 18650s will they be able to handle 6Amp load
(Peak not continous)

Isn´t it dangerous to touch the terminals with your bare hands? No risk of
electric shock?

If I have 2 12volt batteries in series can I charge them with 24 volts? or
I have o charge them separetely with 12 volts?

I have a deep cycle battery that is a 12V system and hooked up to a travel
trailer with an inline charge. Can I hook up two batteries like this to
give my trailer longer life when running off the batteries, or will the
added voltage blow everything out?
Greg Desperado says:

yes you can wire 4 12v in parallel and increase the amp capacity the volts
stay the same .. in series the volts add up 12-24-36-46>> the rc( reserve
capacity also climbs ) so a series 3×12=36 rc per battery is say 140 you
have 3 batteries in series then you have 720min

Hi,Hope you can help.I have a 200 watt solar panel kit I want to use to
power my medium size redfrigerator in my trailer.I have a harbor freight
750/1500 inverter.If I have say 9 hours of sun and 2 deepcell batteries
would this setup be enough to run it?Wired in series or parallel?Thanks in
advance

question:
can you still use 12v units with 24v setup?
i have 3 – 12v 170Ah batteries parrelled. can i make a 24v series bank and
still use with 12v units?
i have 12v audio system and some 24vdc fans would like to use without
buying new 12v fans.
