3.7V Flat Top Rechargeable Battery 30A Real 2500mAh (8 Packs)

Verified 3 charge/drain cycles. Exactly as described. Works great on my smaller drone after i spot welded a plug onto it. Bought these for the high amperage and haven’t had the drone drop out on me yet.

Very useful

These were a direct replacement for a set of dead batteries and they worked perfectly. The price was good.

Great batteries at an affordable price. They charge quickly and last long. Battery case is a nice bonus. Will definitely order more.

It can be a bit of a gamble to order Liion cells here. Some overinflate their capacity claims, often by ten fold or more.These cells however are the real deal. I ran a capacity test on them and they call came back well over 90% of their stated capacity of 2500mah. Not sure who the OEM of these cells are but they do seem to be high quality.They are a bit more costly than ordering from a major reseller, but you get them much quicker so it may be worth it if you need batteries quickly.My only complaint is they do not provide a CDR rating. The product listing says "2500A" which is clearly a mistake. To be cautious, I am not going to use these in anything that will draw over ~7A.If you need some 18650 cells quickly for a relatively low drain device, these are a decent option. If you can wait you're better off going with a well known trusted name brand.

I needed extra batteries for my vape. Works great makes it easy to host swap batteries rather than plugging up the vape itself.

Perfectly replaced the battery that died in my Flowermate dry herb vape and at half the price the online vape stores are asking. What's not to like?

These batteries worked great. I used them to rebuild a battery pack for my Makita power tools
