Making the change from lead acid to lithium - a thread with pictures (1 Viewer)

Thanks, now just have to sort out spaghetti junction behind the EBL to fit the B2B. There are wires everywhere. But with cable ties, some laminate board and some brackets it should be fine

It all looks better with cable ties.

It may seem a bit dim but what setting on multimeter and between D+ and what? With engine running?

Set it to DC volts in the 20v range.

The red lead goes to the D+ wire and the black lead to any ground point that’s convenient.

Should be nothing with the engine off and 13+ volts with engine running.

Check it without the engine running, positive on the multimeter to the D+ and negative to an earth point. Should be zero. Then repeat with engine running and should be 14V or so.

Thanks to both of you. I never mind asking! I know a lot about photography and film making and deep sea biology, but electrics is a dark art!

Hi . f #242. Can you just remove the 20 A fuse labelled Internes Lademodul to disable the EBL30 leisure battery charging?

To return to the question of Isolating the EBL 30 mains charging when on hook up.
Rather than removing the fuse is it not possible to remove the fuse & replace with a RKURCK re-settable 12 V DC 20 amp circuit breaker.
Simply plug the wires using 6 mm spade connectors into the fuse holder. Great car will be required that the 2 wires are not shorted, but make a good connection.
This will isolate the Hab charging, whilst maintaining all the other EBL functions.

I simply pull the 'kettle plug' out of the EBL.

Unfortunately the EBL30 does not have that type of lead it is hard wired. Also if you disconnect the mains, you loose the display panel over the door.

It plugs in with a Wago connector just behind the EBL.

I have lost track of this thread a bit but why not just remove the 20A fuse. This will stop the EBL from charging your battery but leave the mains light on when on EHU and allow the trickle charge to the engine battery.

The reasons I suggest the use of a circuit breaker rather than keep removing the fuse are :-
The CB can be located in a convent location.
The fuse may get lost.
I stops me pulling the wrong fuse.

A fuse would be easier than asking the mother superior for access.

This thread is great. I am towing with the idea of installing solar and upgrading to lithiums….

I finally got round to changing to lithium over the weekend.
I was instructed by SHMBO that I was not to do the job myself, as she could not stand the stress of me doing it & getting it wrong or struggling to do it. I would have had to do it parked up outside the house.
I had the job done by Oaktree Motorhomes , Rob & his crew were very professional & helpful. They answered my many technical questions. The job is great & seems to be working fine. I will have to learn what the system / App will do & how long I can stay off grid etc.
In the end I replaced the 2 X 95 Ah AGM batteries with one 110 Ah Eco Tree LifePo4 battery. I went down the Victron route & fitted a smart shunt, Orion 30 amp B to B & a new MPPT solar controller. There is still room for a second battery if needed in the future.

Very interesting message; would you mind giving us a ballpark figure for the total cost of the total bill as I believe my battery is on the way out and looking to do similar probably at the end of the year.

I love my setup, one of the best things I have done on the Motorhome.

Glad you got it sorted.
