This may not matter to you guys, but I love my Aputure 300D. Its got the best bang for the buck. I had a pair of Anton Bauer V-Mount Batteries, but they cost me like 300.00. I just found a pair of cheaper batteries (190Wh) that last approximately 77 minutes on the Aputure 300D. The brand is D&O Lighting... Just thought I'd share this with you guys. Again, not sure if any of you care about this.
p.s. Hopefully, you don't think I'm just shilling a brand here, anyone has any other battery brands that work on the Aputure 300D??? A lot of them can't handle the power draw. Just trying to be helpful.
