New TN Power 60ah lithium battery. 23cm W x 14cm deep x 21cm h. Would easily replace 120 amp leisure battery. Can be fully discharged without any harm and charges quickly with solar or charger. Does not require any modification to set up. This was standard on our new Autosleeper Warwick but we spend months off grid and wanted more capacity. Tried to buy another 60 amp to mount alongside but like getting hens teeth! Managed to source a 150 amp so don’t need this. Open to sensible offers. New cost is £360. Post at cost or happy to travel an hour or so to meet.
