It's is a great battery rated for 10amp discharge. They have a spotless safety record and will stand up to a lot of abuse. As always, a battery is only a safe as the end user, so you need to know what your setup is going to be asking from the battery. I run my CGR's with a .5Ω IGO-L on a Sig #8 at nearly 8 amps. The drip tip is the only thing that ever gets warm.
Unless I missed something of a major catastrophe (that somehow hasnt been posted on this forum), worries of it's safety are likely unfounded assumptions. These batteries are VERY popular and I havent seen a single report of failure outside of blatant abuse (intentional short that resulted in undercharge/no charge condition...no venting).
