Noco on EHU?

[manderson84]

Hi all!

I have a new German PVC with 2x AGM batteries buried under the passenger seat. I have bought a Noco Genius (battery conditioner) with the idea to prolonging battery life. I have a good amateur grasp of electronics but by no means a professional. My idea was to initially:

- plug in EHU
- isolate (with switch) the leisure batteries so they are not charging from EHU/solar/B2B/driving
- hardwire the Noco to the batteries so they charge the batteries essentially as an isolated system - the batteries would only then be non-isolated/used when off grid, and thereby engaging solar/B2B etc to keep topped up.

I am having some issues accessing the 12V AGMs - I have tried to access the terminals and as far as I see I will have to remove the Ducato seat as per Youtube videos which is doable but fiddly and concious of disturbing perfectly working electronics.

The ideal scenario would be when we arrive a campsite with EHU, plug in and the batteries condition automatically via Noco, and the power we use is taken from the EHU. Then when we off grid, we engage the batteries and run/top up as above.

Given the costs of the Noco and "faffing" to install, is this idea even worthwhile? I don't want to open too big of a can of worms on whether conditioning is worthwhile or not, but wonder if this is a good idea vs simply running, charging and conditioning my relatively cheap (compared to Lithium say) AGM batteries, simply from the EHU without the need for Noco, and replace them in 5 years without the switching between.

Any thoughts welcomed and thank you in advance

Matt

I don't disconnect our leasure battery when at home, I just switch the main charger off, then connect and plug in the optimate maintainer
