SJ4000 LiIo batteries

Excellent post flydiver.

Couldn't agree more. And BTW, I did test the OEM batteries and guess what? Just as you said, they tested higher capacity than my new "high capacity" batteries.

I forgot who, but another member suggested I try Wassabi Japanese batteries so I ordered those and will return these. Rest assured, the firt thing I will do when they arrive is run a few cycles and check the capacity.

Just added to my post when I checked out those Wasabi for possible purchase. I may buy, but I’m not much encouraged. They seem like more of the same BS.

Hope not. I just bought a few. If they fail the cap test, back they'll go too.

If so, I may try to find some authentic OEM's. But that may also be a mouse chase.

I have had an SJ4000 WiFi for a year now & paid about $45 for it on a deal with 3 batteries & 2 chargers.
I have been very impressed with it for the money :+1:

I use them on sport vehicles, my drones, my motorcycles etc.
Very good camera. I paid about $60 for each one and honestly……I rarely use my $300.00+ GoPro anymore.

I use mine on my boat when fishing to make short videos of catches :slight_smile:
I needed a water proof camera & when I saw how much the GoPro”s were I thought I would get one of these SJ 4000”s & see how I got on with it before splashing out hundreds of dollars on a GoPro.
I have been so pleased with it I never bothered getting a GoPro :+1:
One thing I would say to anyone thinking of getting an SJ is to do some research first before buying so that you can tell the difference between an SJ & the far inferior clone versions of it that are out there so that you do end up with an SJ.
The SJ is obviously a clone of the GoPro but if you read the many reviews there is little difference between it & a GoPro but the clones of the SJ are nowhere near as good :wink:

Excellent point. The Clones are no good. You have to get the Authentic Original SJ4000 (or an Authentic SJ5000, SJ6000)

Unfortunately, many have bought the clones then give the real deal a bad name.

Today I received the Wasabi Power SJ4000 Batteries and charger.
For reference, the Wasabi batteries weigh in at 20 grams……IR = 202milli-ohms

They’re on the charger now and once charged I’ll run a discharge test on them to see how they do. Hoping for a good outcome here.

On a side note about the other SJ4000 batteries, the seller of those batteries candys-outlet-store, was very cooperative and helpful with the return of the EforTek batteries and charger.

Curious what the stock batteries weigh.

The original batteries that ship with an Authentic SJ4000 weigh 18 grams

This is what I ordered:

SJ6000

I didn’t see that it says the charger adapter is not included- does it charge via USB, so that any USB charging station should work?

Sir,
I do not mean to be the bearer of bad news, but the camera you purchased appears to be a clone. Not an authentic SJCam.
Authentic SJCameras will have “SJCAM” printed right on the front. Clones are not allowed to do that.

You must be very careful when shopping to ensure that you only buy the Authentic SJCAM. Many have had much lesser results with the cameras that were not Authentic SJCAMS.

As far as charging, the camera has a USB port on the side. All you need is a USB micro cable to charge the battery.

Let us know how your clone works out.

Good news on the charging, not so much on the source of the camera.

It will get more use once the weather here warms up, but I will see what I can do with it in the mean time (once it arrives.)

What would be a good source for the real SJCams?

Thanks for checking in!

You’re welcome :slight_smile:

Any source that has the word “SJCAM” printed right on the front of the camera is usually fine.
GearBest and BangGood both probably sell the Authentic versions and the Clone versions.

I bought mine from B&HPhoto in New York. They were about $58.00 each IIRC

Thanks for the input!

I will check those sources out, and wait to see what I actually get.

I am also considering an accessory package that is supposed to be good for the SJ’s and GoPros- they seem to run $20-$30 for quite an assortment. Do you have any recommendation on those?

I got my SJcam SJ4000 2.0” from B&H Photo. Paid $67, but at least I know it’s authentic. I checked the scratch-off code on the box on their website and it checks out. The only thing I don’t like is the built in speaker. It doesn’t have enough volume even though I set it to maximum. Really doesn’t matter because it plays loud and clear on my computer. Video quality is excellent. So far I’m a happy camper.

Note that the camera pulls approximately 250mA when recording video if the screen is turned off during record.

First test with the expensive “Wasabi 1100mAh Premium Japanese” batteries……
IR = 202mΩ
From fully charged (4.14v) to fully discharged (3.1v) @ 200mA discharge current. 4hr 45minutes

Some checkpoints on the way….

Volts ……Capacity Used
4.14v……000mAh
4.00v……051mAh
3.85v……200mAh
3.80v……258mAh
3.60v……
3.50v……
3.37v……877mAh
3.30v……917mAh
3.20v……936mAh
3.13v……944mAh
3.10v……950mAh (test automatically completed)

So 950mAh is the actual capacity according to my test - 1100mAh is the claimed capacity on the battery.
But…it’s actually hard to find batteries that actually provide OEM capacity so these at least do that.

Since they at least seem to match the OEM capacity, I won’t be returning them, however, cheaper OEM batteries can be found that have the same capacity as these. These appear to be slick marketing of rebranded OEM batteries IMO.

Conclusion -
This is the 2nd so called high capacity SJ4000 set of batteries I tested this week. Neither came close to their claimed capacity.
Don’t waste your money on so called High Capacity SJ4000 batteries. Unless someone else has actually bought some and tested the capacity, the best you can probably get is 900mAh OEM batteries. The rest is probably just money making smoke and mirrors….as mentioned above already by flydiver

Post a link to the package you have in mind……

Here are a couple on Amazon, but I know Gearbest has some, and probably Banggood and others.

I looked at the kits you linked.

Your camera didn’t include any hardware or attaching pieces?

If it were me, I would wait until I receive the camera, see what you’re going to use it for and how. I can’t speak for the camera you ordered, but all the cameras I ordered already came with a very good assortment of attaching hardware. There’s quite a bit included….(again, I don’t know about the camera you ordered) Individual pieces are readily available on ebay very cheap.
