OK. There are plenty of 12v lighting systems available and emergency lightning systems that are used to mark exits in buildings. That got me thinking.
So in the process of building DIY batteries I find myself with a number of cells that work but due to aging, resistance, etc are not well suited for higher demand usage. I debated what to do with these when I considered throwing together a couple of 12v packs with the left overs.
Here is a photo of a pack that is in process. I am waiting on a couple of components and need to drill holes for the BMS. It is a basic pack from Shenzhen Luyuan Technology Co., Ltd. I know there are some higher end units out there but for $35 give or take for shipping, etc I decided to take the plunge. This photo shows some raceway that I sourced for my portable build and was sitting on a shelf collecting dust. It will serve as side supports for the batteries while protecting the BMS and allowing for air flow as well as holding the BMS leads. Naturally I will need to center the middle raceway better and trim the other two but you get the idea.
