This means they output 12 volts, and the sum of the amps of the two of them. G) Your batteries are hooked up in parallel. Generally speaking, try to only work with negative or positive cables at any given time. Otherwise wrap some electrical tape around the lug. If you have little rubber caps or something, that'd be even better. This way if the cable gets pushed out of the way while I'm working, I don't accidently push it into something like a cable/battery pole of the opposite polarity and cause a short (as in Boom, sparks, bad things!). So long as you have no metal and are not working in wet weather, you should be fine so long as you don't let a wrench or screw driver or something lay across both positive and negative cables at the same time.į) When removing a lug from its position on the battery, unless I'm moving it to somewhere else right then, I always immediately wrap a little plastic baggy or two around it (I have small ones that are just a few inches square). It happened to a service tech while I was in a RV repair center once, and he got a nasty burn around his finger because of his wedding band, which he'd forgotten to take off. This step is important because if you have metal on your hand/fingers and accidently touch a positive cable to it, you can get shocked and burned. This is needed for working on the battery cables, as if it is on and you remove the negative wires (ground), you can burn out your LVD.ī) Engine off, so no charging coming from there.Ĭ) Shore power NOT plugged in, so no charging from there.ĭ) If you want to be super-safe, you can throw a blanket over the solar panel, so no power charging from it.Į) Take off ALL jewelry from both hands. If anyone else reads this and sees something I've missed, please chime in.Ī) Put the coach in Store mode, where the red light is on. Oh, 2003 with a 7.3L Diesel if that matters. It seems simple enough, just a bit intimidated by it all and need to be confident I have a plan going in - which at this point I do not (have a clue). I prefer to figure this out myself (with your help of course) versus seeking help somewhere. I'm assuming before I start disconnecting anything that I need to obviously be off shore power, in "store" mode - anything else need to be shut down/disconnected to preserve my life! Which cable is going to the Start Battery, or none? and does that even matter? Should the start battery cable also go through the shunt? So many questions.Īnyway, I'm confused and need a little guidance if there is any to offer here. How do I know what's what? I also expected to see a different config of the two batteries cabled in series, but I don't think they are - it seems like they are independent of each other, or at least have the loads split between to two? I have no idea. Shunt instructions are pretty basic - Attach all the drawing loads to the Negative side of the shunt, run the positive lead to the positive on the battery and done! There's a video on the Victron Site and YouTube, but. Similarly, the shunt can signal the charging system to stop charging the battery once it reaches full capacity, preventing overcharging.Īll in all, a smart shunt optimises your energy efficiency by monitoring (via a battery monitor) the amount of energy being consumed by appliances and other devices connected to the battery, allowing for a more efficient use of power and longer battery life.So, total novice on this stuff, but for whatever reason I didn't expect to see this - all the cables and various connection points. When the battery reaches a predetermined low voltage, the shunt can signal the charging system to stop discharging the battery, preventing damage. This information can be used to adjust charging and discharging settings to ensure optimal battery performance and longevity.Ī smart shunt can help protect the lithium battery from damage due to over-discharge or overcharge. With the help of a battery monitor, you can easily view the amount of current flowing in and out of the battery and the battery's state of charge, which is crucial for managing battery life and preventing overcharging or undercharging.
