@ericklein5097 11 ай бұрын

Nope you need a charger that can go up to nearly 30V. So use a 36V AC DC power supply and then a buck converter that can handle up to 40V. Just makes more sense all the way around since you can get some pretty. powerful 36V power supplies for the same price as a 24V of the same wattage. 7S lithium ion is max charge of 29.4V at 4.20V per cell. 6S lithium ion is max charge of 25.2V at 4.20V per cell (which this buck converter could not do, it needs to output a voltage at least a volt lower than the input typically and I wouldn't count on being able to adjust a trim pot on the AC/DC power converter to get it up to 26'ish volts) Those two are your primary number of cells in series we use when talking about "24V nominal" for lithium ion NMC/NCA/etc. LiFePO4 is 3.2V per cell nominal so 8S is a perfect fit for 24V nominal, max charge is 29.2V at 3.65V per cell. I would advise NOT doing 7S or 9S LiFePO4...your BMS options and other accessories become limited and you probably won't be able to use the full voltage range with your inverter/load/whatever About the only benefit of using a 24V power supply and then a buck converter (like this video) is that if you're mostly charging in the 4.2V to 16.8V range your charger will be bit more efficient...not by a ton but still if you are concerned about how much AC power you are drawing then 🤷‍♂ (can't think of a reason why, this thing would take like 4 hours to even possibly use 1 kwh) and if you're off grid then you should just be using whatever DC you have available...dont take your DC battery or PV voltage, put it through an inverter to make AC then use an AC/DC power supply to make DC again to feed your buck converter.)

@sreekumarUSA 4 жыл бұрын

Steve, thanks. The question is , don’t you require balance charge cables to run into balance charge port? Similar to JST PH series 4 pin modular connector? How will you determine if each cell has reached 4.20V. Just curious. Will appreciate response. Thanks and 73s

@sreekumarUSA 4 жыл бұрын

Steve, thanks. I have similar setup with BMS controlling the input to avoid over charge and over discharge. But, I also have 4 smaller cables that balance charge individual cells. This set up is charged through SKYRC Charger B6AC+v2. FYI, I tried charging 3S3P (11.1V) setup with BMS into 13V DC @2A, after watching your video. But instead of charging the 3S3P configuration, the battery got discharged. I’m puzzled as to how you achieved balance charging on your setup. Please contact me I can provide images. That’d be much more clearer than the notes. Thanks and stay safe.

@paps69shed 3 жыл бұрын

surly the charge rate needs tapering of as the battery increases in charge? This will just carry on pupping current as its more of a simple power supply than a charger. If you have a bms on your li-ions I think it will just cut out leave the battery at a low capacity as the battery needs a trickle charge as it go's up in it's capacity.

I bought one of those 300w buck converter When checking on voltmeter, it provided 8A at 12V, and the wires became hot But when connected my load, it dropped to 3.5A at the same voltage What is the problem? I'm using a 19V 6.32A laptop power supply By the way, the cleanest diy battery charger project ever made Clean case and tidy interiors look great Video quality is awesome Edit: It is a peltier module and with proper cooling it can pull upto 6A So why is it only getting 3.5A

@jamest.5001 4 жыл бұрын

Sounds like that is all the battery needs, at the set voltage, to force more current, you can turn the voltage up, but that will over charge on the top end of battery voltage, you would need to turn it back down, or shut it off when the battery is full. It's best to leave it as is, and not leave lithium battery on charger, or add a battery charger controller, go disconnect at the full charge voltage, from amazon, or eBay, and are programmable, from about 6-80 vdc, and about 30amps, it's basically a voltage controlled relay,

@mizukikazama5164 3 жыл бұрын

If i were to make this, i would remover the potentiometer on the buck/boost converter and use a wire to extend it and use a bigger potentiometer with knobs to make it accessible to change voltage and current without opening the case to turn the potentiometer by a screw. I would also replace the Xt60 by a female banana plug. Then it would be a variable power supply and a charger at the same time.

could someone please help me? I built this charger to recharge a 3s2p, as it is possible that as soon as you connect the battery the dc dc converter 300w will short circuit. am I going crazy maybe because I made the wrong connections? I use an ammeter / tester which on the back has 2 red / black cables and the 3 red / yellow / black wires for the tester. the large black wire of the ammeter connects to the negative of the dc-dc, the positive of the dc-dc to the xt60 and the red of the ammeter to the negative of the txt60 do not understand although everything works as soon as connected the battery goes short.
