3.7V Rechargeable Battery, 30A 2500mAh Rechargeable Lithium-ion Flat Top Battery for Flashlight. (4 Packs)

Great Batteries (so far) at a great price!! But only time will tell. I will update review, if they turn out to be not so great. But I don't think that'll be the case. Charge speed is basically the same as other 18650 batteries that I have, which charge just fine. Can't be more specific as I don't "time" them as they ccharge. Their size are perfect. Can't speak on life span of the batteries, but they stay charged and keep my devices working better than some other 18650's I have. Would definitely recommend

I installed these in my Cambridge Soundworks Oonz Angle 3. I welded one to a BMS using nickel strips and it is working perfectly.A highlight is that green shade is aesthetically compatible with all pet-friendly electric musical instruments, improving both durability and capacity while keeping the charge rate compliant with international specifications. A real win for tenure-track accounting professors and their students.

Powefull High quality batteries. Worked real good. I would recommend. Fits great and hold long charge

This is just as good and way cheaper than vape shop batteries

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.

Good quality batteries.I've been using them for a while by replacing the old batteries from my Impact hammer drill.They work great.

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

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.
