LiPos and safety with batteries

Stop saying things like this you don't know that the device he is trying to power will work anywhere between 10 to 15v.

If the device wants 12v then get a proper 12v charger of the correct rating.

Classic case of RTFM. The listing on Component shop clearly states that the charger requires input power of 11-18V DC at 5A or more.

 
post delelted as I got it off my chest and all that

not gonna get into a row as I am still new but was only trying to help

unless anyone has the exact same model and wants to run tolerance tests

No I do not know but I am not gonna say YES IT WILL WORK WITH ANY VOLTAGE

THAT WOULD BE THE WRONG ANSWER

I said it might and check

hell I don't give a crap if he pays another £25 or so for a shut the f*ck up psu

he should still check polarity or his now £100 voltage kit could be a bit of a mess

Most chargers or psu have the center as the Positive pin/socket

Nope I best shut up coz I don't know what I am on about

You win - I don't wanna get banned just yet if I really speak my mind

No need for a row. All it took was a quick look at the link provided. No drama.

I know that the actual Voltage regulator components - the ST make can take a hell lot more volts than you would expect

Some can take up to 30v dc and output to 9v - that is quite a bit of tolerance - but each regulator will have its own pdf

These are static regulators - there are variable regulators but only needed this type of volt reg & a few capacitors to stabilise it

I have researched this stuff when putting together some electronic circuits so I do know a tiny little bit

And is true when input voltage gets close to output voltage

eg: 5.5v input for a 5v output is bad coz output drops to 4.5v - the regulator circuit don't work too good

Boring bit and completely off-topic but

one project was taking a 18v psu & outputting to 12v & 5v supplys

12v was counter with npn photcell that would trigger a custom batch

the pulse from say 100 batch would then trigger a 5v MOSFET - think that was Negative MOSFET - they come in both types

The 5v MOSFET would activate a solenoid air valve at 18v to spray a silicone lubricant onto the machine to keep it running smooth

The time or number of objects passing counter could be adjusted and the dwell or delay in the pulse signal for long or shorter spray

(as well as an air regulator for the badger spray gun filled with silicon & repostition or add another spray gun)

They above saved machine operator ( ME ) running up & down with expensive cans of silicon

instead cheaper bulk 5 litre can would last a lifetime

Health & Safety - proper ventilation was required as silicon breathing is not good but allowed us to precisely control silicon to minimun - operator free

(plastic sheets were used to keep mist away from us but in the end it was so little being used to get job done)

Sorry - I know nothing I will just shut up to avoid giving wrong advice

No I an not an electrical enginneer but always tinkered with electrics/soldering/programming before i bought my ZX81

don't worry guys :P lets not start an argument over what is right voltage... hanks you all for your help :)

 
phew - hopefully I wasn't BullShitting too much then

soz everyone for getting out my pram a bit - just tried to help
