    Compact Car Alternator & PS Inverter

    Nice! Straight to the point. My current 24v battery is 70ah, it would take quite a while at 200w from empty but good to know I should avoid using the car - this will probably be last resort.

    Compact Car Alternator & PS Inverter

    Question: What is a safe continuous amperage draw from a compact car (2008 Mazda 3) alternator for use with a pure sine wave inverter? Background: I built a LiFePO4 24V portable solar generator. The battery is connected to a Growatt 24V3KVA. I use the AC Input to recharge the 24V battery when...

    Looking for some advice on a 24v 280ah setup for trolling motor

    How did you build the battery on the left? Is that metal box?

    Startled by my Overkill BMS.

    No, that number you saw [12] is not the cell count, it’s the alert count. It send 12 alerts by the time I noticed.

    It’s the app for the Overkill solar BMS. XiaoxiangBMS

    Startled by my Overkill BMS.

    With the battery - nothing. The only thing connected but completely switched off was the Growatt 3000w inverter. The alerts I was getting were the standard push notifications from the various iPhone apps. I didn’t have any other alarms set, I think. I was in such a panic that I ran downstairs. ?

    Startled by my Overkill BMS.

    I woke up to a series of notifications on my iPhone that one of my cells was over voltage….by 16 volts! I thought I had a severely runaway cell somehow and I was going to have an explosion. I ran to the garage to check and there was no signs of damage. I launched the app and found the cells...

    Overkill Solar bluetooth issues?

    Thank you! I will try and find an Android for cheap. I also found out there are compatible hard wired displays for the BMS.

    LCD display with Overkill BMS

    So I have to give up the BT connection for this? Does the BMS have an RS485 so I can use both? EDIT: it does appear there is an RS485 port!

    LCD display with Overkill BMS

    Forgive me for this trivial question but this may be exactly what I’m looking for without having to mess with Arduino or other interfaces. Are you simply using this display connected directly to the Overkill BMS? Also, are you able to view the individual cell voltages? I bought the overkill...

    Overkill Solar bluetooth issues?

    I’ve been running the 8s 100A since 2020 with great success on a battery used for backup power. I’ve been able to power consistent 2000w loads and even surges up to 4000w (~160A) for things like my clothes dryer at startup. It also charges comfortably at 60A for over an hour. My only complaint...

    DIY…am I right?

    Go check out the video. He makes it look so simple LOL. I’m sure there are some components missing from what’s shown in the video. Whatever control/charging unit he’s using, it looks like the ones found on electric vehicles. I see a 12V SLA battery which is probably for the controller. I don’t...

    24V battery for sale - 8 EVE 105Ah cells

    Understood! They’re like gold right now. I currently have a 24v 70ah and was hoping to get closer to 150ah but your 105ah pack is a very tempting price. I’ll contact you if I make a decision! ??

    Which panel to for my Solar Suitcases: Newpowa or Nature Power?

    Here is the discussion where a user is seeing good performance from Newpowa 24v panels. A good MPPT should be able to handle voltage: https://diysolarforum.com/threads/newpowa-solar-panels.21472/page-2#post-257260

    Which panel to for my Solar Suitcases: Newpowa or Nature Power?

    Ahhh I must have missed the part about the size. I was looking into a DIY suitcase but had to put it on pause. I was looking at these Newpowa 210w panels but they are 26x64. Someone did a review and they overperformed their rated power by a little bit. I may be skeptical of the Home Depot...

    Which panel to for my Solar Suitcases: Newpowa or Nature Power?

    If you’re okay with the big panels go find a solar panel dealer where you can buy direct. You said you’re in Colorado so check this business out. They’re selling a 325W panel for $195 and they already have MC4 connectors. By the time you buy the Home Depot panel, plug MC4 tools and connectors...

    New Ecoflow Delta Mini?

    Did anyone catch this new, smaller Ecoflow Delta? They claim 882Wh, 1400w continuous inverter, and 300w solar input. Looks like it retains much of the original Delta design, include the fast AC charging that I like. I was about to build my own portable generator with a 1500w pure sine wave but...

    Any new or used batteries in Arizona?

    Hello! I have a family trip planned in December to Goodyear/Phoenix Arizona. Are there any LiFePo4 dealers - both new or used batteries in the area? I live in San Diego, CA and there isn’t much outside of Craigslist sales.

    Any cool Battery Monitor/Info Display panels?

    As the title suggests, are there any cool battery/system monitors available in the market? So far, the “coolest” display seems to be the Renogy battery monitor. I have the Aili battery monitor on a couple of battery packs and they suffice. Are there any OLED displays like what’s on EcoFlow...

    Would you risk this purchase? Used Winstons

    Update: I’m going to pass. I heard back from the seller and apparently the $50 tag was just for views. Apparently he’s selling “dead”low voltage batteries 1v-2v resting for $25-50. Higher voltage at $150 per battery. Sounds like salvaged batteries and he’s a scrap reseller looking at his other...

    I really hope he responds. Even if they’re 50% capacity it’s still an awesome deal for $400 24v 150ah cells.

    Would you risk this purchase? Used Winstons

    Hello, I came across a local OfferUp listing for used Winston 300ah cells. I don’t know anything more about them and I’m still waiting for a response from the seller. He’s selling them for $50….I’m not sure if that’s the price for each or the whole lot (I wish). I’ll ask more detailed...
