Hello everyone!
I recently bought a convoy s2+ sst20*6 (2.1A) flashlight and a Liitokala Lii-402 Micro USB DC 5V charger.
I’m looking for a decent non expensive battery.
I think that I can use either a button or a flat top, is this correct?
I’m not sure though if I have to buy a protected one or not.
Any suggestions please?
Almost any 18650 cell will do for you; that’s not a very demanding light. The best all-purpose 18650 cell is probably the Sanyo NCR18650GA cell. 3500mAh, 10 amp max continuous drain. Great capacity, and good for everything except high-drain multi-emitter lights. Just get the regular flat-top, you don’t need a protected cell or button top for that light.
In that flashlight and with that charger, a protected is not necessary.
Protected are more expensive than common ones.
Protected ones are no better than common ones.
Under a protection they can put a fake battery.
Buy a good brand from a trusted supplier.
Good brands … Sanyo, Panasonic, Samsung, LG, Sony …
It is not recommended, with some exceptions, ebay or aliexpress.
In Europe, I never bought but it has a good reputation, nkon.nl
Find one that is accessible to you and publish the link, we will help you.
Some batteries I’m looking at:
Sanyo NCR18650GA, Panasonic NCR18650B, Sony US18650 VTC6
A couple of Samsung (25R, 30Q) were also among my choices but after so many reports about fake ones, I’m afraid to buy them. I think I’ll go for the Sanyo.
There’s another online store who claims that their batteries are 100% genuine and they’re providing (they say so) certification about it. Such a thing does exist? A battery genuineness certificate? The funny thing is that I found a customer’s review saying he bought a fake 30Q from this store, lol…
I contacted him and asked him about that “certification”. He sent me a document which contains detailed technical specifications and guidelines about safe use, charging, storage of the battery. A user’s manual actually, which doesn’t prove in any way the authenticity of the product.
