Electrobloc EBL99K and Lithium Batteries

[Southdowns]

Hi Everyone,
My first post and I am going in with a question that I hope someone will be able to answer as its stumped me.
We have an Electroblock EBL99K which has a switch that allow for either lead - gel or lead - acid, however we would like to consider buying some lithium leisure batteries.
Can we add these batteries in and will the Electroblock still work somehow, or do I need to by pass it completely and rewire everything?
Its probably going to be an obvious answer but I have to ask it just in case.
Thank you in advance.
Ian

Cant help you, but will be interested in replies as we have the same ebl.

I also have the EBL99 plus the Schaudt LRM1218 solar controller and considering Lithium so will watch this thread too. My basic understanding is that the EBL and solar controller will charge at max 14.4v and the lithium batteries will not charge to max with this voltage.

Send an email to Udo Lang at Schaudt he should know.

It isn’t ideal for lithium but it will do. The voltages aren’t that far out that it will damage the lithium, it just might not get full. Mine does and I haven’t had problems.

Make sure you set it to gel rather than lead acid though.

More pressing is the battery to battery charger which charges from the engine while driving. You must check that is compatible for lithium.

I guess that is my next question, not sure where my current B2B is, we have a Fiat Burstner Nexxo T740 (10 years old) any help in finding it appreciated. Or do I just add a new one such as the Victron?

It probably hasn’t got one if it is 10 years old. Follow the wires from leisure battery to starter battery, that’s the fail safe way, if there is nothing in there except the EBL, you don’t have one.

I have the Votronic 30 amp one, been great for me. There is a thread in my signature of the steps needed to put one in.

Victron are good as well but have no temperature protection so if you start up in sub zero temps, you will kill the lithium. You really do need one with a temperature sensor.

my lithium has been running on gel setting for 3 years no problem

On he EBL the absorbtion is long depending on model 8 or 16 hours not good for Lithium.
If you are going to do a job might as well do it properly.

With the EBL you can just pull a fuse to stop the charger charging the leisure battery everything else works as normal.
Victron mains chargers with a Lithium profile aren't very expensive.

Thank you for all your responses, now to start looking at the options. Another job for the weekend

My basic understanding is that the EBL and solar controller will charge at max 14.4v and the lithium batteries will not charge to max with this voltage.

Lead-acid based batteries like flooded, gel and AGM need to be charged to 100% at least every week or two to avoid deterioration due to sulphating. Lithium batteries do not have this problem, and in fact can be stored indefinitely at less then full charge without deterioration. They recommend 50% to 60% for long term storage.

Lithium batteries are damaged by over-charging, so chargers for lithium batteries typically charge up to a pre-defined voltage, then switch off, ie no 'float charging'. The float charge voltage of a lead-acid charger will not be high enough to 'float charge' a lithium battery, so it's not a problem.

The main problem is they won't have a temperature sensor that cuts off the charging at zero or below.

How are you going to charge the lithiums..? Solar B2B..?

Yes, both those options
