Thank you so much for your help @bghazzal.
What I don't like about Supe V4Kv3 is that it has very few minutes at full power, only 35 mins
I have doubts with the MW-4300 video lights, I think 4300 lumens may be too few lumens and I hope that Backscatter will release an updated version of MW-4300 with more lumens, like other more powerful video lights on the market.
In the past I bought the Backscatter Mini Flash 1 and shortly after, the update of the MF-2 model went on sale 😬, I don't want the same thing to happen to me again with this much more expensive purchase, 2x MW-4300 > $1.000 🙂
Other cheaper options to consider are Leton Power lights from Aliexpress such as Sealion L12, L15, L24 models with 21700 lithium batteries.... but this is a bit of a gamble.
