second of all most cheap unbranded or unknown knives are complete garbage, you'll save more money and time just going with the well known brands that are already dirt cheap for what they offer

So I should join the Ganzo masterrace?

you can just get yourself good old MORA and be done with the elitist fuckery

if you strictly want an automatic, you should get ganzo

So I want to power an alarm clock speaker thing

It already has a battery compartment, which it wakes 6 1.5v AA cells

Is Gearbest alright for 18650 batteries?

stay away with anything with "fire" in the name

Yeah

Ultrafire batteries I just saw

id get them on ali if i were you

russians actually test them

i know there were some 9800 mAh batteries that reviewers actually tested to about 980

http://anrieff.net/batterytest/index_en.html

does not have most chinese variants but

gives good example of "normal ones"

https://www.amazon.com/Panasonic-NCR18650B-3400mAh-Rechargeable-Battery-Green/dp/B00DHXY72O not that bad price

Thanks for the advice fellas

Looking through links

also don't buy GTF

that "dont touch fire" was suprisingly accurate

never realised until saw this http://www.ebay.com/gds/18650-Battery-Buying-Guide-test-on-all-from-eBay-below-3-/10000000178020340/g.html?rmvSB=true

Lmao

jesu

A single battery actually had advertised charge

Ahahaha

Hmmm

So this speaker takes 10v at 1.3

I basically want to make a rechargeable battery for it

So, li-ion with just like a USB charging module I guess

at 10v .. you want to wallcharger for it

and battery backup

Yeah, the battery is supposed to be a backup for it

It's like an alarm speaker thing

But I want to actually take it places

the switching powersuply with batteries can be hard to do depending on type

Yeah

if its relay then its easy

tho the alarm would need to handle small suddent poweroff when relay switches on/off

aka self-reboot properly

if not done with capacitor hold while the relay clicks
