Tried running the CTEK in “power supply” mode, into the Victron solar controller. It’s a no-go, the Victron needs 5vdc above battery voltage to turn the battery charger mode on.
I have all of my components under the hood, so it’s all subjected to engine heat. What type of batteries ? Flooded Lead Acid (FLA) off gas during charging and should not be in an unventilated space, I think. If I had to guess an inverter puts off heat during use, and may throw off a battery temp...
I drive an average of 1 hour per day, mostly on the freeway. I plug in the charger every other week to keep the batteries fully charged more often. Nothing high draw in the rig. When we are camping in the same spot for a day or so I put out the solar panel , 50l ARB fridge is the biggest draw.
When it’s time to replace the house battery I’ll replace it with an Odyssey , but size and age of battery will still be different. The CTEK I have doesn’t have much as far as custom settings , just a few selections re battery type. I could run it in power supply mode and run it through the...
Question for the group on best charging practices. I have a 2008 GX470, with a dual battery set up, the ACR is a Bluesea Systems ML-ACR. The starting battery is a Odyssey G34 and the house battery is a Bosch G35. My "shore power" charger is the CTEK Multi US 7002. I also have a Vicrton MPPT...
I run a folding 100w Renogy , with a Victon 75/15 mounted under the hood. I use a trolling motor socket mounted to a tab welded in my front bumper. Works great keeping my house battery charged, and Bloody Mary mix cold.
Your looking to charge your starting battery to run the BD scene lights at night ? How much will the lights draw per hour, and how many hours do you plan on running them ?
My CTEK 7002 Mulit USA just bit the dust. It won’t go beyond stage two, but it brings the battery to 13.7 volts after a few hours. It’s only 13 months old so I am working on retuning it to CTEK.
Sounds like the CTEK is faulty. What is the voltage of the battery with the CTEK connected after an hour , and then when disconnected from the battery?
I have a folding 100w by Renogy , Victron charge controller and a Bosch agm. Smaller than my starting battery (08 gx470) . I move the panel a few times during the day to track the sun. Even with heavy use and 90 degree temps no issue with power. I have the same fridge as well.
