charging 4 bricks of 6s lipo at the same time??

[mrfeelgooddrag26]

so i read in a previous noob post "not by me" that you can use a 12s charger to charge 4 bricks of lipo while there still serised and parrelled. i have a few questions

if i was to go this route would it make charging faster?
and if i have 4 bricks of lipo tied together how will i be able to check cell volatge for every cell in every brick? will the charger be able to read all individual cells?
if someone could give me details n this it would be helpfull

No, you can't, if you mean a pack that is more than 12s.

If it is 12s or less, then you could just hook it up to the 12s charger as if it was a single pack already wired for that, yes.

As long as the already-paralleled cells are plugged into the balance connector for the charger just as they are, and only the main output terminals for the *whole pack* (and not individual packs!) are plugged into the charger, then yes.

Otherwise, you'd have to draw exactly what you intend, or else assume the answer is fire.

Entirely depends on your existing setup, which you don't say anything about.

and if i have 4 bricks of lipo tied together how will i be able to check cell volatge for every cell in every brick?

You can't. With them parallelled, then any cell paralleed with any other reads the same voltage. If you want ot do a test on an individual cell, you have to disconnect it from the other parallel cells first.

However, you shouldn't *need* to do this unless you suspect a problem with that cell.

will the charger be able to read all individual cells?

Not if you have anything paralleled. See above.

if someone could give me details n this it would be helpfull

You'd have to give details of your existing setup before anyone can give you details of how to do anything with it.

if you parallel 2 or more cells, they will all have the same voltage. So if you read one voltage, you've read all the paralleled cells voltage too. What you seem to be asking is can you balance charge a paralleled pack all at once. And the answer is yes. And you can do it by just charging one of the serialized packs if you don't exceed the amp limit of the balance wires. I've done it many times. Assuming you're talking about a 12s2p pack that would look like this.

Hook the charger up to the ends, and with the balance plugs paralleled and plugged into the charger balance ports, you balance the whole pack at once when you charge. It's only faster because you do it all at once rather than having to individually having to charge them separately. This assumes you have a 12s or higher balance charger. If you just have a 6s charger, then you could split the pack into 6s sections and charge each half, or then parallel both halves and charge them all as 6s4p.
