Hahahaha you are great , ninja and holly sound effects, man you just made my day.
Keep up with the good work.
LOL Thanks!!!😜👍
Love it as always Joe. Got to love the beeping. I have cells finally back in action on my chargers. But I get 28 cells beeping all the time.
Thanks Man! Yeah now I have a total of 20 beeps lol, I should really make some of them quieter😜👍
That's *really* handy to know thanks for the info!
damn, you always crack me up! Hardcore fan and very grateful
Lol thanks for WATCHING!!!
wow...because of you...i started putting diesel in my car to save money on regular gas. diesel fuel is cheaper ..thank you for letting me know i can do this..👍
😲💥
Thanks for the video keep up the good work.
+HSware Thanks and will do😀🖒
You gotta love that sense of humor :)!
Can you charge LIPO Battery using that charger? I have the same charger OPUS BT C3100. I soldered wire + alligator clips to the far most left port and trying to charge LIPO battery however it behaves in a weird way.
can this charge Lipo Batteries? Does anyone know??
I have 5 Opus BT-C3100's and I love them all just the same, I have no favorites. I paid $39 for a couple, $31 for a couple more, and $12 for one. The $12 one I got from Hong Kong, and yes I had to wait 3 week for it to show, but come on, $12, who cares.
Thanks for the great video, I didn't know about the voltage change, good piece of knowledge to have, next time I might actually read the instructions to find stuff like that out. Keep up the good work
Those are some good prices as well! Ya I wasnt sure if many people knew about that lil switch as I only found out a month or so ago👍
I fliped the switch over to 3.7 but it still charges them to 4.2. My unit is brand new so it may be defective. Does anyone else have this issue?
Very informative.
Thanks Mate!
Ok I'm looking for a less expensive substitute for Eneloops AA and AAA nickel-metal hydride batteries.
I think at one time the Ikea
LADDA 2400 rechargeable batteries were very close to the same performance but I think that's no longer the case or something.
A few months ago I was reading somewhere that the
Amazon basics were a good buy. However I think someone later said they also took a turn for the worst possibly.
So I'm here to ask someone for help, which brand other than premium Eneloops should I buy?
Are the Amazon, Fujitsu, Panasonic or IKEA still the way to go for a less expensive but still decent battery in 2022?
Here's hoping the Opus BT-C 2400 with second generation firmware and hardware battery charger, I received today was a good choice on my limited research I did last week lol.
Please help lol😁.
hi
i was looking at Opus BT-C3100 charger circuit board, now i'm wondering where is load resistors or Mosfet !!! do you know ?
Should be the "bigger square" resistor at the end of the slot. Think it says 150 on it. Did yours quit working?
Hello , I'm new to these types of chargers and the specs while great might not be accurate (? ) I use eneloop aaa a lot and 18650b. I can't decide between this and the miboxer c8... help? Many thanks!
From all of my testing(100's and 100's of cells on this charger) The fan can be a little noisy but so far its pretty solid! I would recommended it to anyone. A BIG disadvantage for me about the miboxer c8 is it doesnt have a discharge function and that option is the only real way to test a batteries capacity to see how much life is left. The miboxer c4 I believe has the discharge function but I cant say how good or bad that charger is since I havent used it yet.
@@AveRage_Joe I'll have to get both then.. x/
I am looking to buy a charger to mainly charge AA & AAA batteries, I often see the Duracell and Energizer chargers, $50 is the maximum I want to spend on a charger, also is it better to buy a charger without a fan, are the Duracell, Energizer and Uniross chargers better than Opus and are Amazon Rechargeable batteries the best and are they made by Panasonic but what charger should I buy, I want my batteries charged within 2 hours or faster.
For AA & AAA id get a cheapo as long as you can change the charge mah.
I am going to buy a Energizer charger that comes with 4 AA NiMH 1300mAh Rechargeable batteries, will this charger also be able to charge my other 4 NiMH AA batteries that are 2800mAh, 1300mAh to 2800mAh is a big increase.
Yeah mah shouldnt be an issue!
? 4 ya do i need to change that dipswitch as my opus only charges to 4.15v? whatever setting it on now is the way i got it thanks!
If your charging regular 18650s then keep it on the original setting. Most chargers will have that + or - % and 4.15v is just fine. There isnt much difference from 4.15 to 4.2 when capacity checking the cells. 👍🔋
AveRage Joe not much of a difference but I want that difference lol. That's like a 80 vape puff less than full 4.2 volts lol wish mine hit 4.2 volts smh
0:12 Hiyaaa!!! Never gets old.
🤣🤚💥🤘
Any thoughts on the Liitokala Lii-500 charger vs the Opus or Foxnovo? The LiFe capability is nice but the price difference was the kicker for me. The features seem pretty nice on the Lii-500 but I've had issues with robustness. I've had to replace two of the 8205s (dual n-channel MOS FETs) inside after accidentally touching two battery positives together while removing them from the charger. Lets the magic smoke out of the smd fets on the charger circuit. They were pretty obvious to find as they were bubbled and charred. Easy and cheap to replace though (the fets are like 14 cents each). Have you had any channels go down on your Foxnovas after incidents inserting or removing cells?? Thanks!!
+kirkb4989 I have a Liitokala on the way to check out and another brand as well. I plan to compare all of them once here. I really like the foxnovos, Not one single problem since Ive had them. All slots working great!
I look forward to your comparison! My issue is that I've left the paired batteries tied together (I've designed a 3D printed holder to accommodate paired cells) but that sometimes leaves the "tails" (where the pairs are connected to the pack BMS) hanging out so MY process is more vulnerable to "bad touching"... I really like the operation of the Littokala. When you get it, keep in mind there are two test modes- the FAST mode measures how much charge the battery takes after being discharged, and the NOR (for normal) charges them first then measures actual discharge capacity which is what I THINK you want to measure. I always use NOR test mode. If you do manage to let any smoke out, the part that gives up is the 8205 fet and it is fairly easy to replace- if you need some, let me know- I bet your Paypal account has my email address...
30 seconds in and already hitting the like button. ;p
Nice!!!! Thanks!!!👍
want to ask...ive aa rechargeble battery already break in..from 1.2v to 1.6v..but when i test on opus c3100, the indicator only show 1.49v...can you explain that?
I believe that variance is in a lot of chargers. Ive noticed it in most of my chargers!
WanMafi According to lytge-info.dk, the C-3100 momentarily turns off charge current b4 reading battery voltage. That takes intelligence others might not have? It would cause lower readings.
I haven't seen NiMH battery intended to be charged to > 6.x volts?
what's the difference in the BTC and the bt3100
I've heard the bt-c3400 is identical to this one. Do you happen to know if the 3400 has the same switch?
I would imagine it does but cant say for sure.
What is the LifePO4 discharge test termination voltage? 2.5v? 2.0v?
I dont actually remember since I only had a few of those cells! I typically do the laptop cells!
lol same one I got.. box and all.
The problem with the Opus chargers is the contacts, if you press harder on them, you get totally different values and possibly better values too.
Nice!!! I hear that as well for the contacts!
Laaaaaa..the almighty opus. Too funny bro!
I drilled a hole in the back of the case of mine to access the "secret switch" lol
I have the digital charger 4s, which I think is the same as the foxnovo.
Have always found the opus doesn't fully charge cells. Also it is generous with capacity readings, usually about 100 mah more than the 4s testing the same cell.
They are a good cheap unit though
Its amazing that there isnt a switch on the outside!! Yeah the digital 4s is pretty much the samzies! If Im around when the discharge cycle is done Ill usually swap them over to the Tp4056 charger and those only go up to 4.15ish volts and Im cool with that. I havent compared the 2 yet but will here soon to see how much difference there is 👍
Offgrid Dreaming haha yep mine very rarely will charge to full 4.2 maybe its to help with battery charge cycle life. Like a lot of cordless tool batteries do. They charge under 4.2 on each cell. I still want 4.2 darn it I wonder if i switch to 4.35 I would hit full 4.2 lol
Its always a great idea to have a hidden switch on mainstream electronics - really increases the usability factor. ;P
I couldnt agree more lol🛠👍
their is a switch on the in side on the right hand side when its up side
down looks like it changes the voltage 4.2 and 4.32 and 3.7 volt is labeled
on the board
Yes sirrr!
Joe I bought one of these off of Ebay and it never showed up, so I was a bit gun shy about who to order it from next? You solved that problem for me, Thanks!
Yeah for some things ebay is IFFY!! I think Banggoods price is pretty avg for them as well!!👍
For all the readers wanting to know if you can fit 21700 in the BT-C3100 V2.2. YES, YOU CAN! I already did charging and discharging of about 100 cells - 21700 and so far all good.
Nice!!!! Good to know!
Yeah, Great video!
Thank You!!!🔋
What about a LiFePO4 14430 3.2V 450mAh 1.44Wh batteries, what is the maximum charging rate you would use?
Id use the lowest setting!
Does the warranty expire if you open it to put that switch on a different mode?
Hmmmm thats a great question! I honestly dont know!🤔
I need to get something like that I don't remember which make it was but I saw one with a fan in it and that seems like a good thing to me
It seems like a good charger to me so far but Ive only had it for a week or 2.
How do you select battery type on this charger?
Regular Li-ion, Ni-cad and Ni-mi you dont need to change anything. If you want to do the lifep04 then you need to take the back off and move the switch.
How do you know the 26650 are LiFePo4? Is there a part number printed on the heat shrink tube? Not all 26650 are that... There are also regular 3.7V/4.2V Li-Ion 26650...
+bcmasur The part number is printed on the cell and yep not all are LiFeP04🖒
I Love your marshal-art....lol
LOL every time I say Banggood I feel like I need to do that!!!😜
Is it better than Xtar VP4 Plus Dragon? I see it has lower minimum charge current. But i'm asking in terms of charge quality. Most of people say no, because Opus is manufactured and reworked by many people. However Xtar focuses constantly on it and probably the same people are making the technologies to the chargers. What you think?
I think the xtar is a slightly better charger and I think the IR test is waaaay better then opus. Dont get me wrong, the opus is a good charger(faster too) but the xtar is closer in capacity test with many of my other chargers.
@@AveRage_Joe Thought so. I think the same, charging quality on Xtar is top looks like 👌
I added a computer fan to the bottom of my opus,,,,,amazing difference!
I hear a lot of people are doing that mod!🔨🔧
thanks joe i just flicked 3.7v switch so can sort my lifepo4 22650 out of ebike for my electric longboard
.steve
Nice glad to help!!!
are those sunkko spot welders anygood and would i need the extending jaws to do do wider packs or not
as my soldering crap.i has a solder station cheap one worked ok but i broke solder iron an cant get replacemnent.wel thought i did get replacement clone but it started to smoke as was not wired up right.can still use as hot air gun .
I'm confused. You charged with the internal option switch at 3.7V. Shouldn't the resulting end-charge voltage of your cell be somewhat close to that? It showed 3.36V and you got over 95% of manufacturer stated capacity. I never worked with LiFePo_4s before so I guess it could be a chemistry thing.
It has magical trickery for powers!!! No Im just kiddin, Im not sure how it actually knows but you would think of charged to a higher voltage. I actually could have recharged it to 3.7 and then the cell settles on its own to 3.3v I think I have heard that before for these types of cells. Ill run the test again and hang out so I can see what it does and let ya know👍
Two thumbs up
👍👍😀
hahah love the video work :)
LOL Thanks😆👍📽
love your zany video kenny everett style rip.
🤘
Hi. Nice video. Do you suggest this chicken? As far as I learned after many hours of searching this is one of the best chargers on the market. I'll mainly use it for charging 18650 3500 mah, 14500 750 mah Li-ion, eneloop aaa 750 mah ve eneloop aa 1900 mah Ni-MH batteries, discharging them for maintaining (don't know whether I need it), learning how much energy inside them and their how much life span left and other issues which I don't know. Because I don't enough have knowledge on the subject, batteries. Is it possible to do this with this machine?
Yeah this charger is a great charger for your needs!
@@AveRage_Joe Thank you Joe.
Should i switch to 3.7v instead 4.2, to charge 18650 batteries?
For regular 18650s just leave it on the 4.2v setting!👍
thank you! ;-)
Huh, I guess my Voltcraft IPC-3 has the same switch, good to know!
Awesome!!! Thats good info to have!👍
I'm just here for the BANG GOOD! LOL
+bcmasur 🤔😀🖒
Dudes like the coolest ever lol
🤣🤘
So this is what yo use to test the capacity of the cells?
+Emanuel E. Muniz Rosado I use this now and the FoxNovo F-4s!
did opus can break in AA rechargeable battery?
It can charge all kinds of batteries yes.
Have you tried the X-TAR range at all?
I have an xtar dragon vp4 plus. Great charger as well!
@@AveRage_Joe What is a good budget option? Have you tried the LiitoKala Lii-500?
Yeah Ive used that one as well. Its good. Honestly it really depends on what your doin. If your testing 1000s of 18650s like I was doing, the opus is a great charger for that cause its fast. If your just charging a few random batteries here and there, the lii-500 or zanflare are cheap and work great.
After testing 60 18650s slot one went bad. Continues to charge. And always shows active even when battery was removed.
Damn that sucks, Ive tested well over that now that Ive had it for a few weeks. Have you taken it apart to see if anything is burned up?
Just sent it back. I figured you get what you pay for.
I hear theres a few different manufactures for them and maybe the German one is a good one.
My math could be wrong. The power supply is 3 amps at 12 volts. So it you are charging 4 18650s at 1 amp each at 4.2 volts. How does that work?
No your math is correct, it should be a 4amp power supply!
I'm going to see if my BT-C3100 v2.0 has the switch inside, I thought it autodetected all that but I'll find out. Meanwhile I'll see if I can spot problems on the board for my second slot always thinking there is a cell in place, and if I can fix the spring on the fourth slot. It looks like that v2.2 doesn't delay as long after switching modes to take effect. If mine has a switch, I'm going try some 18650 cells in discharge test at 4.2V again and switch it to 4.35V and try discharge test again and see if the numbers are any higher. Most 18650 cells handle 4.35V just fine although not much power comes out of the 4.2-4.35 range.
+bcmasur I would think it has the switch. The instructions say it cant auto detect the li-ion cells. Yeah take it apart and see if you can fix it up!!!
bcmasur have you found a solution? Mine third bay does the same!
so i should do resistance test also as battery shut off while on ebike
Resistance test is good when battery is full charged!
@@AveRage_Joe been looking at sunniko spot welder any good?
If you go with a sunkko I hear you should get a 220v www.banggood.com/custlink/KGKGWCLUz7 cause the 120v versions dont have enough UMPH to do a decent job. Thats what I hear from everyone that has gotten the 120v.
Can you fit four 26650s in it?
You Betcha!😃🖒
Been using 3 of them.
+Gilbert Pfaff There nice chargers😀🖒
Perfect timing! I just got mine yesterday and already planning on buying more. Have to shop around and see how the prices are and delivery times. I got mine from Amazon because I know there is easy return if I get a lemon. Didn't know about the hidden switch. Saw one review that showed $59 price and know I won't be buying from there.
+Lloyd Prunier I like it so far. If you cant find a better price, use the aff link below😉🖒
What exactly is this switch for?
I thought voltages are automatic
Switch is for LifPo4, regular li-ion or Hi voltage cells!
@@AveRage_Joe I thought the automatically detected them? Guess I'm thinking of a other charger
Yeah you have to choose!
1:43 What happened with D12?
D12 looks fine on my screen? What do you see?
The Opus shows about 10% more mAh than the Foxnovo,but the opus is 4 times faster than the Foxnovo :)
Interesting!! Do you have both also?
Discharge to 2.8v not 3v !!!
Hahahaha music is great 😃
😂👍
Hi,
Is the 3,7V switch really for charging Lifepo4 (Lfp) , I'm not sure...the best maxi charge for Li-Ion is 4,2V and not 4,35V...And for Lfp it's 3,6V MAXI and not 3,7V (best at 3,55V) . It can accept 3,7V but it's not good for the future of the battery.
I think it would be better to use this switch position for Li-Ion storage.
I made a little hole in the backcover at the good place, so i don't need to open everytime i need to change the voltage.
This charger seems not built for LFP, it's a shame, it was not difficult to include this function .
The Top would be to have the choice with a 3,6V (3,55V) position for Lfp , and 4,15V for Li-Ion...Some Mah less, but much better for battery life.
My understanding is lifepo4 is very accepting of over-voltage charging, perhaps up to 4.2 without significant* damage. But, I'm wondering if it's not really 3.65v, and they just rounded up. Given the chemistry's tolerance. ???
Yeah they are forgiving for sure!
Based on all this, I'm taking the plunge and going to try lifepo4 with this charger. I wonder what criteria we could use to confirm a successful experiment.
So when did Shia LeBouf start doing TH-cam videos. Cool!
😆👍
I need to get more Opus chargers.. can't have enough of 'em when I get a batch of cells to process!
I pronouce LiFePO₄ like "Liffy", much easier and distinct!
LiFePO is awkward to pronounce and sounds too much like LiPo, which are lithium polymer pouch cells.
Yeah its a pretty nice charger!!! The beep is quieter as well and a different tone lol. In a different part of videoing I kept saying lipo lol
There's another feature - pressing "slot" after you change mode will cut the 10s wait short.
They do seem to have reliability issues though - the third slot on both of mine failed after a few weeks, so am now down to only being able to test 6 at a time. Still, it's good that there's some level of redundancy.
Hopefully they'll produce an updated version that'll address this.
Wonder what makes the slots quit?
No idea, just one started misbehaving and showing stupid values making it untrustworthy, and showing it charging when there was no cell there, and the other just spontaneously blew something and let out the magic epoxy smoke.
Still, the others appear to work fine for now!
Another tip, don't let one fall off your lap onto its dc connector - the plug is longer than the socket, so it pushes through and breaks it. Fixing it by trying to make solder bridges to reconnect the contacts was tedious but ultimately successful!
sweeeeet :)
+Today, for lunch Your sweeeeet 😆
I know you from one Up The Sleeve Customs
😆🤘💥👍
be nice if it was a software switch for that
Yeah it would!
or at least leave a groove in the plastic so we could change it without taking it apart
how does this compare to the litokalla engineer?
A lot prefer this charger over the litto Kalla But I think the Littlo Kalla is more accurate. At least from the chargers I have. This charger is faster since it can do 1a discharge!
lol @ the karate kid over there in his pj's...too fucking funny i tell ya. I want to bang 10 of them opus's fer sure and BANG them real GOOD.. muahahahahahaha... wanna detail more on the operation of the unit with different batts?? whats the unit input voltage and how many amps is the power supply required?
LOL you know it!!! HIIIII YAAAAAHHHH!! Bang Bang😏 Yeah I can do that in a future video for sure!!
mine states the input voltage is 5V at 3amps
The funniest part: 1:17 :D
🤣🤘
So funny
+Squidlings 😆
I have a similar charger for Nimh and NiCad batteries. I really don't care for it. It is slow to charge and the menu isn't very user friendly. In the end it does the job, but I have other chargers that work better.
The opus seems to charge fairly quick compared to some of my other chargers. This one has a few things that Im not fond of but all in all its a great charger!!!
For me it's the user interface, I find it odd and not easy to use. It works well though. I have a different charger that I use more to do ease of use. I use this one when I want to recondition or freshen a cell. Not a bad charger, just not the easiest to use.
Enough!!! Just give the information..
Shame u can't charge to 4.15v
True that!🖒
You can find the very same item on Aliexpress for 70% of the price...
+cenariusbg Sweet, Ill have to take a lookc😀
WoW Second time you reply to me
LOL no pay but they do send the stuff 😀 I try to respond to all comments if possible while I still can. Yeah 32 isnt bad at all! Thanks for watching and more to come!👍
Y r ur eyes so red and glossy?
Mmmmmmm not sure but I do most of my videos after work from 1am to 4am?😆
First comment whaaaat Does it smell like china?
Surprisingly no lol!😜
