Made my own 18650 Charger

Usually i’m using my Nitecore i4 for charging my 4 pcs Panasonic NCR18650A
But lately i’m tired waiting overnight getting all of them fully charged

Already looking for other option, but it’s seems not much charger with better output current
that’s why i take the other way, made my own battery charger :slight_smile:

Here’s a picture of it, but not fully populated. I had to test it first to know how its perform
Current setting about 1.5A/slot

That’s rather high charging current for those Pannies…
But your PCBs look very nice.

Hey I like your work there! Looks great! :+1:

Hey great idea where did you get those PCBs?
For charging 18650GA, 18650-30Q this is great.

I am still a bit puzzled if I should get a 1.5-2A fast charger.
On the other hand I got still 2 Miboxer C4 from review GAW that I can get on each 1A 2 slots, as well as my Klarus with 2 slots 1A

Thanks for comment

I just follow NCR18650A datasheet, and its say 1470mA. So i think it still safe

Made my own PCB, and using TP5100 as Controller
For fast charge, maybe someone more expert can explain pros/cons

Nicely done!

I charge my 30Q and GA at 1.5A just fine, probably a bit of capacity loss after a hundred cycles but these batteries are so cheap now, and time isn’t :smiley:

BTW I have 4x GA’s in a YZXstudio powerbank and with a 40W power supply it charges at almost 2.5A per cell, after 50 cycles still within 90% of original capacity.

If you looked just a little harder you might have found a charger that charges faster…

Aggre with you will34

Sorry Enderman that is only 2 slot
I need more :slight_smile:

Well the one you made was only two slot so I assumed 2 was fine…
Personally I would have gotten two of the nitecore chargers and just mounted them to a wall together or something.
5A is pretty good, my RC charger does 6, soon I will upgrade to more, around 7-10A.

Looks really nice, congratz. Where’d u get the cradle from?

Cool work mate. What is your input voltage/amps? Are you using a DC adapter?

@Enderman
Buying a Hobby Charger is my first option actually because they attract me with large output current
but after reading some of review, look’s like it’s to complicated for my brain just for charging a battery

@dekozn
Thank’s
You mean Battery Holder, right ?
Keystone 1048 Clone AFAIK
I buy locally here, this is a easy to find parts for Vaping stuff

@everydaysurvivalgear
Thank’s
12Volt Input, Yes I’m using a AC Adapter for CCTV Stuff with 12V/5A
it’s cheap and quite good

Looks very well done! Do those modules come with the header pins?

Nice little diy there are a handful of chargers that charge faster then the i4 isn’t only like 350mah with 4 cells. Just about any other charger on the market can do 4x1amp about 3hourish charge time. Liitokala 500 $20 opus 3100 2.2 $30 but with only two cells can do 1.5 or 2amp per cell with 4 limited to 1ampx4, efest luc charger 4x1 amp 2x2amp

Seems a little high for NCR a cells the spec sheets base there life cycles on worse possible conditions in the spec sheet the charge and rated drain rate. If you run the cells hard why run them hard charging. I have 12 ncrb that are in sets of 4 for powerbanks that probably have 200-300 cycles each on them. If they charge in the power bank it’s at 250ma if I need to go I’ll take them out and use other batteries and they go on the opus at 500ma even after all those cycles they still all test over 3300 @1amp discharge. Most of my other newer cells are charged at 1amp. Only use 2 amps occasionally on 26650 or if topping up a 30q or hg2 I’m using for vaping before I leave.

Maybe you could make a switch to go from 750ma or the 1.5a it would more then cut in half the time of the i4 with just 750 and be easy on the cell

1amp is usually enough unless special needs for the cells quicker. I have cells on standby so I don’t use the 2amp option much. But what’s good is if you do buy a opus or sc2, xstar rocket is they all charge at lower currents as well so your not forced to use the higher current. So if you buy one its like every other charger unless you want to move it to 2amps

If you looked a little harder, you would see in the OP it says not fully populated, testing to see how it performed :slight_smile:

Anyway, it’s Blf and some people have been known to tinker around here lol.

Nice work!

Already test those two slots and its seems fine
Both have CC ~1.55A with CV 4.20X Volt

Will try to mount another slot/module asap

@lightrider
I made my own pcb for module too

@speed4goal
Thanks for your input :slight_smile:

@itsonlyme & StandardBattery
Thanks :slight_smile:

You have one very cool looking battery charger in the works there. Nicely built and designed. :+1:

Yep that’s what I meant. Looking good dude. I like the red pcb. You gonna try to build it in,make a case or something for it? One thing though, to bad u can only charge 18650 cells with it. But if that’s the only type u gonna charge it’s a great unit. Way to go.
