    Battery isolator functionality question

    Thanks! Most solenoid isolators keep them disconnected until the engine is running then it connects them (ie via accessory signal or similar). I want the batteries to stay isolated 100% of the time but to both charge from the alternator. My original thought process of tying one battery to stay...

    Battery isolator functionality question

    Oh yeah, duh :) I don’t know why I didn’t think that battery 2 would then become the source and they’d no longer be isolated. It’s so obvious once I read your post haha, thanks!

    smart shunt audio alert to visual

    I think you’d have to use an output from the shunt (if it even has one) to send a signal to a downstream device/controller. which shunt do you have?

    ARGO FET 200-2 Battery Isolator

    I don’t know if you “can’t” per se but it’s not recommended and highly uncommon. has it been done, sure, but it’s very much the minority. if it were me I wouldn’t unless I knew each charging source was smart and could monitor/adjust based on voltage/current since each charging source would...

    Battery isolator functionality question

    I have a question about battery isolators I haven’t been able to find an answer on. I understand it’s purpose and function under normal use/wiring, but I’m wondering if there is any functional difference to my simple wiring schematics below. from what I can see, batteries would still be...

    I need a torque wrench or two. Which is your favorite or favorites for solar applications?

    In general, you probably need two. One for the really low range and one for mid range. So try to determine your specific applications/products to understand what torque ranges your install will require, especially on the lower range (less than 15Nm). If you don’t need the lower range for your...

    I need a torque wrench or two. Which is your favorite or favorites for solar applications?

    Guess it depends on what you’re tightening. I tightened my EVE cells to 6Nm. 6Nm is 53 inch pounds fyi

    Camper Van 12V/48V Electrical System Design Advice?

    Previously I did a 12v setup in my fifth wheel but am now planning out a van build. I really wanted to try something different and do a 48v setup this time… partially just because :) I had most of it planned out but ultimately decided to do a 24v setup solely because I plan to only have maybe...

    BigBattery Rhino 48v alternatives?

    Hey everyone, I’ve been looking into a battery for a van build, I’m looking for a single contained battery bank such as the BigBattery Rhino. At first glance the Rhino is exactly what I’m looking for, but I want to know what my other options are but really haven’t found much. Anyone know of...

    Final LFP Charging settings with Batrium BMS?

    Yeah it’s a little “hidden” Hardware, cellmon tab, look towards the bottom left for a small text/button that says “more…” You have to click the Edit button on the cellmon tab before making any changes to that pop up.

    Final LFP Charging settings with Batrium BMS?

    thanks! I kinda figured it would need some work. there is a decent video on YouTube from a gentleman that talks through each of the settings but he uses other lithium cells I believe, not LFP Settings updated, we'll see how this does.

    Final LFP Charging settings with Batrium BMS?

    omg yes, I started following the Victron configuration awhile back then figured out quickly it's just wrong haha.

    Final LFP Charging settings with Batrium BMS?

    Sorry for the delay, yesterday was a travel day :) ah yes, completely makes sense on the generator, charge up faster to use less fuel. I was thinking at it from a charging/balancing perspective not from a fuel efficiency perspective. Here are my current Auto Level settings

    Final LFP Charging settings with Batrium BMS?

    Why would the generator charging algorithm be different than shore power? It wouldn’t know the difference it would just see the 120vac as an AC input. I have an ATS with generator priority so even if connected to shore power, if the generator is running it will switch to that circuit. Yes I...

    Final LFP Charging settings with Batrium BMS?

    got it, thanks! I'll set it this way for now until I dive deeper into this. really appreciate all the info!
