How can I determine the output of my onboard charger? . I do have a multimeter
Set the multimeter to volts DC and put the probes on the battery terminals. Sometimes the onboard charger is just a 13.8v power supply like our Elddis one was. To see what it's up to you've either got to watch it or get it's user manual.. Or Google itHow can I determine the output of my onboard charger? . I do have a multimeter
It's in a 96 Kontiki 640. Built into the power supply unit in the wardrobe. No labels at all sadly. Everything is working fine, I am thinking of adding a second 110 amp leisure battery and was just curious how quickly (or slowly) it might charge them.The the make and model number and I'm sure one of us on here will find the info.
If it is that type the Batteries will never get a full charge and will only last a couple of years. If you want your batteries to last you need to replace it with a decent multi stage cgarger.It’s 10 amp at 13.8 volts. It will really struggle to keep on top of 2 x 110 amp batteries. Depending on. How much demand. Rule of thumb min unit capable of charging at 10% of capacity
I do have 270 watts of solar on the roof so during the summer I think the battery gets fully charged from that. I want to add a second battery to give more reserve through the winter. Can I add a second freestanding charger to use through the winter without disconnecting the existing one?It’s 10 amp at 13.8 volts. It will really struggle to keep on top of 2 x 110 amp batteries. Depending on. How much demand. Rule of thumb min unit capable of charging at 10% of capacity
Not in an Autotrail, cables are way under size for the existing install.Im in a similar boat. I am thinking of remmoving the od 10a charger in the sergant control panel and addingt he Victron30 amp multistage somewhere.
My question is if I find the exisiting output cables from the old 10a would the cables from that to the batteries which I am (upgrading to lithium 200a) be ok to take the new current.
Ah, yes there is a switch on the top of the box. I can just turn it off, then I would have a back up if the new charger failed for any reason.if I recall correctly, there is a switch to turn the built in charger on/off. If you install an updated charger, remove the fuse for the built in one. Otherwise the new charger will see the constant 13.8v put out by the old one and assume the battery is fully charged
