Need help finding a battery for Sanwu Challenger

[ZachThePwn]

I just purchased the challenger, https://www.sanwulasers.org/product/challenger and noticed it didn't come with batteries. Trying to find one that works for it but I'm clueless when it comes to batteries. Are there any good rechargeble batteries that work in it? And if so what charger should I use.
