struggling to find a leisure battery that fits behind passenger seat

[pondering]

Just in case it’s of interest, with the same height restriction I opted for a 60 Ah Victron Energy AGM Super Cycle battery that is stated to ‘cope’ with ‘depth of discharge’ better than the ‘average’ battery: https://www.victronenergy.com/upload/do ... ery-EN.pdf

Possibly just marketing but it fitted the space... I also have a 50w solar panel on 5m leads (for flexible positioning) that keeps the battery charged when the van isn’t going anywhere, and both connected to an MPPT controller (also Victron) that I can connect to (Bluetooth) and monitor via an app on my phone. Works for me.
