Unless I missed it, I can’t see any mention of unprotected?

These seem to be protected, so are unsuitable.

They look like protected cells to me. They have the extra ridge at the positive end which is where the protection circuit is usually located

Indeed it does say unprotected in the spec but the photo seems to be that of a protected cell. Might be worth an email to confirm 100%

its really amazing just how this battery has so many versions but they all refer to it by one common number!!!

also it seems like 95% of the "button top" are also "Protected"
and about 95% of the "flat top" are "Unprotected"


*IF* they had went with flat top i think this battery thing would be less of a hassle.


the only tiny gain is in identifying the + / - ends of the cell i think....

The number 18650 denotes the size of the battery - 18mm diameter, 65.0mm long. And yeah it is super confusing with all the different varieties - protected, un protected, button/flat/nipple top, different power (amp) ratings, different capacity (mah). Total minefield. And not all of them even meet anywhere near the specified capacity or power ratings. Some brands are utterly dreadful. As a rule of thumb, if its advertised anything over around 3500mah then its an utterly false claim, as the tech doesnt exists to make them any higher than this. Also, generally, the higher the mah, the lower the power rating tends to be. What makes things more confusing is they give 2 power ratings - max continous and max pulse. Continuous is what we need to be looking at.

I’ve just rang the company I’ve ordered them from, he has told me they are definitely unprotected cells

I wish deagostini had given us 6 of those battery chargers.

Mine have taken an average of 4 hours each 🙄

Forth one should be finished soon, put another one on before work and the last when I get home.

Fingers crossed he should be working tonight 😁

These are the exact ones I've purchased - now I just have to wait for my final delivery as DeAG have delayed my delivery by 3 weeks for the THIRD month on the trot! #NEVERBUYINGAGAIN

I went here for my batteries too. Just an fYI - they carry a Panasonic battery that is rated at 3400 mAh for a few cents more. Best prices I could find, and they have a price match guarantee too.

These do come up when you use the unprotected filter on their site so they should be ok

Hi is there any reason why a battery charger different from the one supplied cannot be used? Seems daft charging one battery at a time. The volt check can still be done. Auto chargers monitor each individual battery.

It's a balancing charger that checks each individual battery so that you have a balanced set and highlights any that are not good to use.

It is characteristic of lithium-ion batteries that the one with the worst condition will determine the performance of the whole pack. If one of the six batteries is ‘bad’ (with a very low power level, or coming to the end of its recharge cycle), it has the potential to damage other ‘good’ cells, and even the protection circuitry.

The charge/check process is only done once unless you change the batteries as the mains charger deals with charging thereafter

I still haven't got any batteries for my r2 I have looked online and there are so many different types.I waited for issue 100 for more advice on what batteries to purchase and none came.Sat here with a wonderful looking statue of r2 d2 (He is a very good model actually and have really enjoyed building him ). I have been pointed in the right direction by fellow builders on which batteries to get (they are now out of stock ).I cant understand why deagostini would leave us to source our own batteries . I would have preferred to get the right batteries from deagostini

I thought the battery offer was just going to be a link to supplier, not DeAg offering the batteries for sale themselves. With that in mind, I suspect the reason its taking so long to give us the website address is because DeAg are waiting for the supplier to get enough stock ready so they dont sell out straight away.
I've waited a couple of years to get R2 ready, I can wait another couple of weeks for the battery info.

Just ordered some batteries from 18650.uk and with the discount code (thanks 18650.uk)

I know we have a charger supplied...I also have one of these:

https://www.amazon.co.uk/gp/product/B074DT3NLF/

(MiBOXER C4 Universal Smart Battery Charger 4 Slot LCD Display 18650 AA Charger for Li-ion Ni-MH Ni-Cd AA AAA AAAA C 22650 18490 18350 RCR123)

Would there be any reason that I can't use it to change the batteries for R2?

And according to CS, 98,99 and 100 are on the way...

Cheers,

Lee
