Pls house needed lithium battery charger 24V/15A

Buy two laptop charger, connect in series, buy 20A buck converter and step down to 29.4v

officialfestus:
the cells are how many amps each?

2.5amps each. I get 40 amps on 15 parallel cells

this won't be of any good.

officialfestus:

Why?

occfx:


Why?

it's a waste of resources and time, getting a recommended charger is more preferable to me.

Yes but but cost... That 15A charger will be nothing Less than 15k - 20k. But 9k will DIY and still be reused for other voltage and purposes.

Powmr 60a genuine MPPT Solar Charge Controller available for 95k firm. It will come with a dc battery voltmeter, worth 4k, that you can connect to your battery to help you see the voltage of your battery in real time

is this still available?

a laptop charger will charge very slow. 🐌

It should not... A lithium battery simply wants a Constant Voltage and a constant current. The good buck converter will do just that.

This won't last, those bulk converters are not that strong, both the charger and the converter will burn in no time when they are working at the peak of their current

Depending what you mean, almost all electronics come from China and if you do the right thing you get the right result. Laptop charger is charging the lithium ion of the laptop and it's not burning out. Good buck converter with the right ratings and heat sink still delivers. Well, like I said, it depends on what you mean. If you don't do it wrong thing it won't work.

do you use one, if yes, how's the performance?

Yes works well, though 12V...planning to do 24v.

fuckboys:

Always available

but it's slow when charging, because I once use it.
It takes almost 10 hours to recharge an 80a Samsung 26j pack of 12v.

You aren't suppose to run them at their peak. The setup works, it's what I use.

Simply, I prefer it to regular charger.

HNY man.
Is your charger connecting in series or parrell?

I don't use laptop charger, I use switching power supply blocks like ones attached.

Happy new year guys.

Please I have a question, if after you have coupled your cells, and there is a bad one, how do you find the particular cell that is causing the fault

First it depends on the pattern of build i.e spot welded or copper wire(fused)

If it is spot welded,you have to dismantle to correct d error but in case of copper wire coupled one,it's easier.

One way of detecting faulty battery most time is which is generating excessive heat?

Self discharge by testing the battery voltage drop

It's recommended that test is carried out on the sells b4 coupling.
