Wow a transit specific site.
Ford transit battery under seat.
A z plan pricing information is not available on all ford websites.
Normally the rear battery under the driver seat is the engine battery.
Also some dealers may choose not to participate in a z plan pricing.
How i ve been looking for you.
Mounting a leisure battery under the passenger seat by anthony1664 thu jun 18 2020 11 52 am my leisure batteries under the middle passenger seat i went with a wooden ply base and then used battening to screw it down and firmly fix it in.
My transit 250amp alternator dual battery arrives in october so i can t look but do assume that ford has a battery isolator between those batteries doesn t seem like they would build a machine that would kill itself.
In addition some vehicles trims or options you select may not qualify for a z plans.
Great info here thank you for all the research and hard work.
