Low cost battery option

Recycled batteries.
I was contacted this week by a company offering battery packs. they are classed as recycled but may be new batteries that had faults and were returned. They are then remanufactured to make battery packs. 

Ironing out the kinks.
The company  was looking for advice on bringing these to market as they do represent good value and are two quality cells. The packs have different issues which are checked and rebuilt or replaced so that they work again. this means that there is variable costs and time in recycling the packs and cells for use in home power as well as cases and BMS systems.
Costing the battery packs as there is some work involved here, this will be announced on our shop. You would be saving around 40% on your home storage.

We are yet to set out the battery format, and yes this is UK based business.
