Not to sound like I’m a shill for TrustFire, but if you go through the manufacturer directly, they don’t sell any ridiculous-claim batteries, like 5000mAh 18650’s. Just trying to dispel the common misconception that all *Fire batteries are crap. Reviews seem good from what I can find on their 26650’s, and others have tested the protected 32650’s with good results. I’ve had good luck w/ their midrange 2400 mAh 18650 protected batteries, for example. Their sales rep that I have ordered quite a bit from recently has been nothing but honest and open with me, and I have to respect that/feel obligated to pay it forward.
TL;DR: Real TrustFire batteries are a good deal, if you can trust the supplier.
