olcoolone wrote:What was the state of charge of your aux battery to start with, what was the ambient temp and where is your battery mounted?The battery started at 12.9V then went to 13.2V. Is now up to 13.5V after doing a few short trips to drop kids off ect. The ambient temp was in the mid twenties celcius. The battery is located under the bonnet, along with the battery isolator.
Why did they say a Piranha DBE180S battery management system was better then a DC-DC charger and do they sell DC-DC chargers or know what they are? No-one I spoke to said that the Piranha was better than a DC-DC charger, I wanted something simple that I could wire up, that had reasonable warranty support and would be under bonnet mounted, within my price range.The Redarc website states that the DC-DC charger shouldn't be mounted near the engine.I contacted Redarc to get info on their DC charger and they didn't reply, which says enough about their level of support for me... With installation Ranox was above my budget.

I think what you are seeing is surface charge.Yes I am sure that I am seeing surface charge, I just noticed it goes up and down between 13.1 and 13.5 depending on when i check it.
You can mount the RedArc under the bonnet as long as it is away from engine heat, sorry to hear that RedArc didn't get back to you.Wish I new that a week ago...
A battery 100SOC at rest should have between 12.6 and about 12.9v depending on battery and the environment.
You might be pushing _ _ _ _ up hill to get three days out of that size battery and the Engel. I probably wont get three days but hopefully will be able to get two nights out of it, so effectively one full day without running the car...
Keep us informed.Will do.

Your Engel draws more power than the Waecos, you'll be flat getting 2 days sitting still but mine can (but this might have lead to ruining the battery). I'd be going for a run every day. If Ranox was out of your budget, the smarter Redarc one is too.Yeah the Redarc and Ranox are about the same price, I was looking at a cheaper Redarc that probably wouldn't have been big enough anyway...
One of the reasons I bought a good battery charger was to ensure the battery was full when I left home so I could get through a weekend with confidence. I try and go for a bit of a run every day to help charge the battery. The ranox is on the drawing board but it is not too critcal yet.I have a charger that I will use to charge up the auxillary fully before we go on a trip to ensure it is lasts as long as possible

Have you seen the CTEK D250S DC-DC 20A Battery Charger. Are these new? I have already purchased the Redarc unit and it is working great. I saw these whilst looking at the 12v25Amp charger. Heres a link but there is only a picture. Thought somebody may be able to provide some more info.

I purchased a redarc BCDC 1220 after the advice on this thread. Where have you been installing these units in the Hilux? Would prefer under the hood where i can get easy access to see charge state ect, but just a bit concerned about the heat under the bonet. Just don't want the output to derate.
From your experiance how does it cope with the heat and does anybody know what temperture we could see under the hodd of a D4D under normal conditions?
Cheers
