Hello. Just noticed you said you will adjust the the current to 4-5 Amps. With a power supply that can deliver a little over 4A that's not going to happen as when boosting the voltage you will detract from the current the laptop power supply can deliver minus losses. Not sure whether you knew that but just thought you might be interested. It will work to give you enough to charge though and it is a very good idea.
@@JoeyDiazInASpeedo without taking losses into account you have simple formula Pin=Pout so double the voltage and you get half the amps out, since P=Voltage * Current. Hope it make sense.
I appreciate that you are making instructional videos for those of us needing visual learning. I noticed that the pc power brick has a ground and it looks like to power leads wound together. Really hard to see how you are wiring the XT- 60 plugs. I realize you are trying to keep video short, but some of us. namely me, really want to be sure we are doing it correctly. Just a thought, not a criticism. Thanks for you help.
each power supply will be different most have negative and positive, the 3rd wire is probably detection or signal .. just make sure the red and black are connected use a multimeter to double check red is the 19v input
I'd like to see the result when the cells reach the set voltage. Most bms stop charging cells at the bms designed cutoff voltage so will some cells reach that? How would the bms deal with that? It would be good to follow up with testing each cell after a charge cycle to see if a 4V balance is maintained.
thanks for your instructable/video, permit me one question, you are using a boost convertable, as others i have seen use a buck/step down convertable , so what is difference ???
Good video sir, anyway can you bump up the out put current more than the input current can produce and what is that 4.1 volt per cell, is that charge voltage per cell. Thanks
Big like for this video. Please give more info about the full charge status info. How do you know when to unplug the charger / laptop module ? And please, more info about the app who measure current on your your phone. Thanks! ☝️
but theres nothing to protect from overvoltage? this will have to be monitored while charging and mannually disconnected at the desired charge level. seems dangerous
i love it ill be using mine to do the same thanks i one the 1200 watt unit ,i messed up and ordered the small ones 5 pack like your using with no current control darn it lol i have to get more .i wander how long these this last if if under like 70 percent load fer a long time months weeks years.i wonder how warm the switching chips n such under that booster board board run heat wize mounted like that on top on power supply lacking air gap ? who knows lol be blessed thanks fer video
So, where is the cell monitoring connection? Those are lithium cells, and therefore are the ones we keep seeing exploding and catching fire in peoples homes etc. Lithium cells need balancing for best output, cell life and, of course SAFETY! I've been using lithium batteries for radio control hobbies for decades, and every single cell is monitored by the charger so that none of them will ever be over charged. And if you say these batteries don't need that, please explain how the fires that are shown on news channels are using any different method to yours. (I'm sure you've never had a lithium fire in your home by the way, and neither have I)
Can you please tell me the application you are using to check what amps is coming from your charger, I'm using the same 400w boost module but my multimeter can't check the amp. Thanks mate
it will only start to damage the cells once they become fully charged, so if you can pull them off as they hit the 40v mark, sure you can .. forget that they are charging and you will be cleaning the walls and furniture
I'm so stupid... I didn't get the idea of stepping up one of my 2045664 10s chargers for my battery to 13s and then I had to wait 15 days for the charger I ordered whahahaha
Turn this guy here you say,well cant see what your turning defeat the purpose of you video. He said just go get a step-up converter hook it up to a charger and follow the instructions I guess cuz your instructions are telling me what to do

This is probably the best video on using a boost converter to charge a battery. Thank you!

That’s wrong, upping voltage does not take from amp, amp stays the same and the voltage increases there increases wattage of charger
@JoeyDiazInASpeedo
No he's correct you can't get more amps when increasing voltage

What happens if you leave it on the charger and go away. Will it stop charging on its own or would it damage the battery pack?
If the module is cc / cv then yes

they burn after few weeks

Why not simply connect two identical laptop chargers in series 19 volts + 19 volts

@@anwin85alon That doesn't make sense.
@@anwin85alon Eh?
what if the battery has bms to stop over voltage?
@@MayhewCloutier What if the BMS is cheap and fails?
Mine heats up too much

if I use an 84v charger on a 60v battery but pull it off before full charge will it damage my battery?
it will only start to damage the cells once they become fully charged, so if you can pull them off as they hit the 40v mark, sure you can ..
forget that they are charging and you will be cleaning the walls and furniture
