Battery for S2 UV

Hi, long time reader, first time poster here.

I have ordered a Convoy S2 UV (with LG - this one), but I don’t know what battery I should get for it. I’m going to give it as a present to a friend who is into reviewing hotels, etc so he can use it to see how clean the rooms really are… So I guess the battery should be protected as I’m not sure how familier he is with these things.

I’ve read quite a bit here on BLF about the inside diameter being a bit off in the S2 and that not all batteries fit well. Can anyone direct me to a battery with protection that makes a good fit and can be ordered here in Norway? It doesnt have to be a top-spec Panasonic/LG/Sony and I dont mind waiting for for a package from China, but from what I’ve read, Bang Good, AliExpress, ebay should be avoided. Problem is Norway is outside EU so Ecolux, Torchy, 18650.uk and a lot of others are either not sending here or the cost of freight is very high. I’m going to order the lii-100 charger from Littokala Aliexpress store, but I guess its out of question to order batteries from them (I’ve read this?) Is Fasttech a good option?

any decent cell from the big manufacturors will do
the current is low you can even use protected medium drains or even low drains

I would recommend 3500mAh Medium drain protected

Thanks, I´ve looked at that impressive sheet. So i guess there shouldnt be a problem with the fit, regardless if the battery has protection or not.

all Convoy 1x18650 do also accept protected batteries

also very entertaining is the bottom of the list
