Can't find any notes about this, so apologies if its been asked before.

If I fully charge my batteries on Agile Live at say anything & anytime at below 13p, can I effectively revert to using the grid until the price goes to above an upper limit, say 20p ?

I don't want batteries charging at 13 and discharging for my own use when the grid is only at 13.5 (for example)

I don't export at all.
