Gday ppl
I have a 12V/15A charger and was charging a 100ah lithium battery, the last i tried to charge my battery it stayed on bulk mode for over 3 hours and very hot (almost to hot to handle). Is this normal? When I look at the history of the VictronConnect connect app the figures were:
Elasped 3.16hrs
Charge 49.8ah
does this appear normal?
my apologies if this is a silly question as I’m a newbie to batterie/chargers
thanks

The charger produces 15A p/h so 3 hrs reults in 45Ah of power. Numbers look right from that perspective. With such a small charger it will take almost 6-7hrs to charge the battery. Ensure you have decent cables and connections, the charger profile is set to Lithium and adjust to the manufacturer's specifications if different to the default and ventilate it well.
yes I’m using the li-ion setting
I’m using the cables that came with the charger
and I have moved it to a better ventalate position
cheers

What cables that came with charger are connected between the charger and the battery? I have
purchased 5 of these chargers and they did not come with cables. I use 4mm red and black twin flex
to keep a 60A/h battery charged with everything running cold. Recently connected another charger
to a 100A/h gel battery and also running cold using same 4mm red and black twin flex.
I see you have the IP65 rating charger. I have and older version (Multi XS 7000 which is 7A/h capable. It is connected to a 70A/h battery to keep it at optimum condition when not in use (vehicle) It appears that the cables are about 2.5mm (judging from the physical size) If I start the vehicle say twice in succession and put the charger on after that it steps up to ABSORPTION level and stays there for a while before changing to FLOAT. It does get fairly warm but not excessive and returns to warm to touch when at FLOAT. Mine does not have Lithium capabilities but yours has. I assume you set yours to Lithium mode. I would be worried if it gets to hot to handle (electronics and heat don't always go well together as a combination. If the battery is okay then I would take it to a place that could try it as well and confirm if that is normal heat expectations. It is a closed and sealed housing so it does get a lot hotter than the previous picture of the IP22 rating version that I posted which is in a metal case.
