I would strongly disagree. Inexpensive batteries are everywhere now - this is the work of market forces, not some guy on Youtube - and he's one of a handful of people who you can trust to do an honest dissection of a battery. You don't have to be a rocket scientist to check for a handful of basic safety features and characteristics, which is more or less what he does.

Will Prowse has been around a while now and this is the first time I'm seeing a critique of his safety habits. Please elaborate as he's widely respected in the solar/storage community.

Given how many years of experience we have with Will Prowse, it would be helpful if you could elaborate a little on why we should trust your opinion more.
