Does anyone know where I can buy 18650 battery in packs.
Indian sites are selling individual cells for 40-50, but I can't just order 10 because they will just send 10 individual cells from random, different manufacturing batches(which will mean that all of them will have slight differences in voltage and internal resistance). I need to connect them in parallel so they must be from same batch.

No yaar, grocery stores just keep non rechargeable low drain carbon-zinc ones or atmost very low drain rechargeable nickel ones.
I am talking about those lithium ones they use in vape machines etc

idk, directly go to the place where they manufacture it, try there, or wherever you live, every city has a hardware market or electronics related market.

Directly contact the manufacturer
That's the best bet if you want the same batch with that amount

No, forgot about that. I don't want to get scammed again yaar, I brought 2 from an Indian site called robu.in that apparently has very good ratings and both of them died permanently in just 2 months.

Retarded rant but buying components is India is just painful in general, they strap a +10% to every individual piece basically, some things like certain capacitors and diodes are straight up not even available.
Don't even think about buying some better quality amp chips, they will change the marking on the cheaper ones that do more distortion and sell it to you. The listing seemingly have random completely.wrong information attached for no reason many times. They lie about the material when selling inductors or transformers, they lie about the manufacturing date, they lie about the tolerances, they sometimes sell completely burnt out MOSFETS and then blame you for burning them which is easy since there is no way to tell.

+the customs office is apparently corrupt so you can't even buy from foreign sites without paying bribes, even if you do pay for the expensive shipping.

I built a drone in class 10th with some friends, then we broke the base and everyone kindoff forgot about it. I have some free time, I was planning to revive it with a new battery and 3d printed base+ some new code and sensors etc.

It's just a taser I made using the core of a old mobile charger transformer. I wired it so that it has a turns ratio of around 1:5000 so 12V input turns to ~60k volts, which creates a plasma arc that jums around 5cm. Basically the bottom image
