eBay Amazon and b&ms would NOT be a good place to buy batteries. Rtd vapes or illumination supply buy from the manufacture, so no clones.
All batteries have knockoffs afaik. I don't waste time trying to find the cheapest battery... Saving those few dollars could cost you your vape hand and face if you aren't careful.
You want authentic high drain IMR batteries with a continuous amp rating that you will build under. It is not recommended to use the pulse rating as there is no standards with these tests, so each manufacture tests differently.
