battery efficiency losses

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery which employs vanadium ions as charge carriers. The battery uses vanadium's ability to exist in a solution in four different oxidation states to make a battery with a single electroactive element instead of two.
For several reasons, including their relative bulkiness, vanadium batteries are typically used for grid energy storage, i.e., attached to power plants/electrical grids.
Numerous companies and organizations are involved in funding and developing vanadium redox batteries.

    Is it still worth exporting your home battery?

    I'm talking about Octopus reducing its export tariff to 12p (from 15p). This reduces the differential between the import price (7p off-peak) and the export price to 5p. It was 8p, of course. It was my assumption that at the 8p differential it was worthwhile exporting the remains of my home...
