Hymer Smart Battery System with third Habitation Battery discharge rate

[07790]

Hi does any one have the Hymer Smart Battery System with third habitation batery? With the solar on and everything in the MH switch off the batteries are discharging at the rate of 20% in 9 days, is this normal. The MH has a factory fitted battery system and the MH is only 3 months old. According to the sales brochure this system is suppose to last for up to 10 days of normal usage.

From what I have read on the web lithium batteries do discharge but only at a rate of 0.5% to 5% per month, so you think I have a problem or is it just normal for this system.

Did you ever get a resolution to your issue? I ask as maybe a similar problem. Just taken delivery of Hymer 580 with same battery system as yourself. Brought it home on Saturday to load up and then into outdoor storage ie solar available on Monday. Habitation battery showing 86% Monday and 71% Thursday. That seems like a lot of current drain with everything off. Solar according to panel supplying current appropriate to light conditions.

My situation:
Looking to buy a Hymer MLT 570 or XPERIENCE - but not the Hymer Autonomy batteries/chargers/controllers pack as I would be off grid for 1 or 2 months at a time and it is not adequate for that.

Colin H - Can I ask what Solar Regulator your MLT has ? I have the Smart Battery 2.0 but no factory fitted solar. I'm just pondering the best way to add it - the easiest is to cable it to solar socket on the EBL but I'm not sure which solar regulators will play nice with the Electroblock EBL 402.

You will need a Schauxt/Lipput LRM 1218 or a Votronic, neither of them work particularly well with Lithium.
Also running through the EBL you will lose about 5%.
Far better to use a Victron and connect straight to the batteries.
