    Victron charge controller - Temperature

    Looks like pdxfrogdog covered that in the post above yours, confirming that their battery monitor (and assuming smart sense bluetooth temp monitor) will provide that to the charge controller and allow low temp cutoff

    Need a little help

    Thanks for the clarification, guess I picked up somewhere that charging two dissimilar batteries in parallel is okay but discharging dissimilar batteries in parallel requires additional considerations.

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    Thanks, you've helped a ton in the...2 weeks I've been in possession of lithium batteries and trying to get things ready for the season. Still unsure of how one can benefit from this renogy unit though running lithium.. making it more suitable as you say. My high voltage disconnect relay that...

    Victron charge controller - Temperature

    Cool, I ordered the 712 with temperature sensor today. And yeah guess that'll still send info to the controller via VE network. Prayers that works fine even though they'll be all of two feet from one another. Still would prefer the reliability of a wired sensor. And thanks john, you must...

    Victron charge controller - Temperature

    Pretty sure I've read that the smaller Victron charge controllers have internal temperature sensors. But all search results across the web for victron+temperature discuss temperature compensation, and the most it touches on lithium is "set this to 0 in the app". I don't want to charge if it's...

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    Looking at that Renogy chart on the last page for this product, what are your thoughts on its lithium charge options? 13.0, 12.8, 12.6 for Type 1 (whatever that means), and Type 2 (also, whatever that means) of 14.6, 14.4, 14.2, 14.0. Even the lowest of type 2 exceeds 100% capacity and is...

    How many actually use 120VAC when off-grid?

    Jeez I never saw my top of the line 2017 touch bar 15" blabla MBP use anywhere near that, running two displays, running iOS simulator and Android emulator, compiling at the same time from Xcode and Android studio, with a zillion chrome tabs, photoshop open, youtube videos playing in HD.. Hell, I...

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    I don't know, those were just numbers to try and illustrate the spread I observe between one cell and the three others when trying to fully charge on my living room floor with this ISDT hobby charger. That of course was for the sole purpose of immediately throwing a load on it and seeing how...

    Need a little help

    I know you meant parallel hah. That's probably not a bad idea though, for all the time people have spent looking at these isolator threads trying to figure it all out. If you have a pretty consistent load, like you primarily run a fridge, maybe charge some phones, and run an inverter...

    Need a little help

    I also have a second battery in my truck bed and solar on the camper shell's roof. I've just relied on the 200w up top to charge the two lead acids I've had in there, because I hate running wire - especially thick wire. And I have a smart alternator and apparently finnicky charging system on a...

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    Seems like deligreen (mfg)'s website is borked temporarily and asking for a username/password when trying to hit the domain. Wasn't like that the other day. But "QNBBM balane specs" on google returns a couple other places with specs. Guess it's 6a continuous for sure, and a site or two...

    $200 5KW Portable Diesel Air Heater

    Some guy who tests a ton of these heaters on youtube (in depth power and fuel consumption tests, sound ratings, sound ratings with a bunch of mufflers, double mufflers, the works) said running high grade kerosene can cause the fuel pump (I think) to burn out. If I recall correctly it's because...

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    Someone else on here - his inspiring reply: jonyjoe101 If I could have found an active balance bms all-in-one board I would have gone with that, but his linked post (and his other post on secondlifestorage) made me think I should order one and give a try. My 90ah 3.2v x 4 cells are like a...

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    Thanks for posting this, though I don't quite know how to interpret or conclude if this product will be a viable solution for me. I'm going to run without a BMS, instead using an active balance board paired with a Victron battery protect (cells are bottom balanced and have practically no...

    New DC to DC Charger From Renogy-20 amps or 40 amps-Flooded/AGM/GEL/Lithium

    Guessing that means you've concluded you can't tell it to stop charging at say... 13.5v or something? That was my plan with my lifepo4 house battery.. figure out what I usually consume in a day, add some breathing room, and then keep it between like 20% and 80% charged. Guess I have a relay...

    Awesome, hope my experience mirrors yours. Did you use batteryblocs too, or what? These are lithium iron phosphate batteries so safer than what you may be thinking. And i’m hoping to find them to be easier to charge, or faster at least. Solar + large battery charger run on the generator for...

    Too true, look at any Ali* product review and discover 90% are from across the pond. 75% are in Russia. It’s tempting, too tempting... i’ve found quite a few prismatic cell listings with Russian gibberjabber translated in to a solid evaluation of the product and a youtube link of their findings.

    I’m more excited that you’re excited, I thought you had blown the whole concept to pieces in your first few posts. I have a large dewalt ds400 box that I put a stereo in to, with 8” subwoofer and 6.5” speakers. It was powered by an 18ah lead acid battery that has since failed. So this pack or...

    I need to remove the slight curve from one of my series connector bars, but otherwise the plates themselves are held on very well by the nylon nuts and bolts. While the blocks do lock in to each other, I think a lot of the structural integrity comes from adding the threaded rod through all the...

    Of course, and it depends on what you're doing with the pack. I waffled on stating cigarette lighter port because really, I'm just going to use the panel mount round "cigarette lighter port style" USB offerings on whatever toolbox this goes in to - at least one with USB PD. I'll probably throw...
