What amp charger was it?Battery was on 240v charge for maybe 4 hours max ?
Hmm...What amp charger was it?

It is capable of charging faster than other battery types. How fast it does it depends uon the amperage of the input devices in particular fhe alterernator and EHU.Watching with interest as Im thinking of going there for the same set up. I thought lithium charged much faster.
You said it was on mains charger for 4 hours?We are travelling around and no access to ehu yet. I did ask this morning at Offgrid before we left and he wasn't concerned as it was overnight. But thought after an hour or so on motorway it would be charged a bit more.

Hi, not wanting to hijack this thread but my GEL batteries have died & I have a CTEK DS250S DUAL & a CTEK smartpass system and am thinking of going for Lithium. Do you know what the difference is between the D250S and the D250SE & 120S smartpass?All depends on what your DC-DC charger can put out and what the state of charge of the battery was when installed.
Lithium batteries cannot be shipped above 30% charged which would put your battery at around 85A in the bank when it was shipped.
Let's assume that your supplier / fitter hasn't put in any extra charge (something that I would personally do as a courtesy in their shoes but hey ho..)
Let's say it's taken a little over an hour to do your 70 miles that would mean that you've put in 40A in an hour.
That wouldn't sound unreasonable to me - depending on what your b2b is supposed to be capable of putting out.
All depends on that initial state of charge though.
This is partly why I went for the CTEK DS250+Smartpass because it will put out 120A which makes a massive difference to larger battery banks.
Did you have a victron battery fitted? If charging on the battery is turned off then that's why it's not charging.Looked at the victron app and said my victron bms is switched off remotely or by bms? No idea why or how to switch it back on.
I've no dea what my alternator is, how do I find out ?

On his Hymer DL the fridge will be powered from the relay in the ELB so assuming a 50 amp XS B2B he should be getting near to 50 amp charge.Is your fridge on during travel? I bet you are not putting in as much as you think, after you account for the loads as well. If you haven't got a shunt, you are at the mercy of the bms. you need a full charge with good absorb time to have a reference point to relate to.
The power still has to come from somewhere to that relay, is either the b2b or battery.On his Hymer DL the fridge will be powered from the relay in the ELB so assuming a 50 amp XS B2B he should be getting near to 50 amp charge.
70 miles 1½ hours driving will only put a max of 75ah into the battery.
The alternator is 160 amp so plenty of power avalible.The power still has to come from somewhere to that relay, is either the b2b or battery.
Lithium is capable of being charged much faster than any equivalent lead-acid-based battery. That means it's OK to fit a more powerful charger. But if you stick with the same charger it will charge at the same rate as before.I thought lithium charged much faster.

You mean it bypasses the b2b straight from alternator?The alternator is 160 amp so plenty of power avalible.
