    CALB 3.2V 200AH LiFePO4 Source in US?

    Ok, looks like the answer to that is no, lol. How about a good source in general? "Lifepo4 BATT Store" aka blslifepo4battery.com is definitely not a good source, and any that I can find that will sell me 1 have no feedback at all.

    CALB 3.2V 200AH LiFePO4 Source in US?

    Hello, I purchased 8 CALB 3.2V 200AH LiFePO4 batteries from a source on Alibaba. One of them has gone bad, and after several months trying to get a replacement cell and having no luck, I find myself needing my RV in a couple of weeks. Now I need a cell ASAP. Does anyone know of a source for...

    Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    Yes, I've noticed this as well. The above solutions in this thread aren't really solutions, just ways to etch out slightly higher current out of Float charging and then damage your cells long term as a consequence (ie. use a high float voltage as the one and only charging strategy). The only...

    Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    Maybe someone more knowledgeable can chime in here, but won't Lifepo4 be degraded by a constant 27.8 charge? I've also noticed when I charge with a 28v float, I'm not really using full charge current.

    Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    Woggs1: You ask what a "Good Plan" is? At this point I think a "good Plan" with MPP Solar equipment is to dump it in the trash and see about getting your money back from your credit card. Mine failed to charge completely yesterday. Their tech support is useless. They do not even...

    Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    Yeah, my thoughts exactly. Might just admit I got ripped off on this thing and replace the entire setup, since the one thing it actually does, it does it horribly. Still waiting on a reply from tech support. I try to give them plenty of time to show how terrible they are.

    Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    Ok, sounds like yours does the same thing mine does So it's not that mine is defective, it's just that whoever programmed it had no idea what the application was. I can't imagine any application where you'd actually want the batteries to almost fully discharge before recharging. Strange that...

    Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    Did you ever determine how it switches, and when? Mine pretty much never goes into Bulk mode. the only time it will charge is if the Float setting is higher than the current battery voltage. I'm using the same float voltage setting you are, but if I do this, the battery will go down to around...

    Stuck on 24v mpp all-in-one setup

    Did you ever get this system up and operational? I've implemented virtually an identical system, and I've never been able to get my LV2424 to charge properly. It seems it only charges in "Float" mode. It won't "Bulk" charge. No matter what it is set to, it will only charge to whatever...

    8s-16s BMS Instructions?

    So I bought this for a 8S Lifepo4 pack, based off Wills recommendation. I can't find any instructions anywhere, particularly for the temperature sensor part, and nothing at all regarding an app. Anyone have any info on it? Seller has good feedback, but is of zero help.

    Charging 24v RV house system from 12v battery/alternator

    Yes, current is the issue, even when talking about 12v to 12v (which is what Will's video was about). with 12v to 24v current limiting is a given.

    Charging 24v RV house system from 12v battery/alternator

    So I have a fully functioning 24v system in my RV. 1000w solar, 4.8kwh lifepo4 battery bank, MPP Solar LV2424 inverter/charge controller. It all works great. However, despite a lot of peoples assertions that I should never want to charge the batteries off the alternator, there are times...

    AliExpress Dispute?

    I just gave up. AliExpress wanted a video of it not working properly. I'd have to install it, and freeze it? Pretty much what you get from any Chinese company: "send me a video" Except this wasn't the company.

    AliExpress Dispute?

    Only $127 so it's not the end of the world, but it's sort of the principle at this point. Daly assured me multiple times that they would send me one with a separate thermocouple and 0deg C low temp protection. They did not even bother, and when I asked what happened, they just sent me a...

    AliExpress Dispute?

    has anyone had any success with an AliExpress Dispute? My Daly BMS which was supposed to have low temp protection (went back and forth through messages to make sure they understood before ordering). AliExpress denied my dispute, even though I referenced the messages. If anyone has any hints...

    24V for vehicle specific systems (cheaper/more efficient(?), but how much)

    Just giving my take on the original question. I went back and forth on the math for my current build and decided 24v with a couple inexpensive 12v converters was a better option for one main reason: Allowed me to use the MPP Solar LV2424 that Will reviewed. Simplifies everything in the...

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    Don't apologize, that's what I'm asking for, lol. Trying to decipher their web site and product descriptions to figure out what comes with what, and what I need to order, but looks like that might do it. Do you order through Alibaba? What's the usual transit time? Thanks

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    Yes, would love to find something local. That was my initial question: Does anyone know of any? The only reply I got was this one, but no one has tried it. Didn't try Ms.Zhou directly. If they have no one who answers emails, I doubt they have english speaking reps who know the product...

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    Already done that twice with two other BMS. Total loss both times. Not just the money, but the time as well. With as slow as China is moving right now, getting anything is a month or two process. I've got $1800 worth of batteries just sitting here, waiting to be able to complete this...

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    Has anyone had any luck getting hold of anyone from LLT POWER ELECTRONIC ? Since no one has actually used the 8S model yet, I wanted to confirm a couple of things with them. Their Skype link doesn't work, the contact page isn't working, and the email I found got me nothing after two days...

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    Ok, maybe I'm missing a video somewhere. Thought Will had only looked at the 4S. Currently trying to contact LLT POWER ELECTRONIC but the Skype link doesn't work for me and they don't appear to have email. Already ordered two crappy Bms's from China at a $200 and 3 month loss. Like to make...

    Finally found a LiFePO4 BMS with Low-temp Charging Protection

    So I fell for Daly's claim that they could sell me an 8S BMS with low temp cut off. Got it yesterday (finally), and no low temp cut off. Now I get to test Aliexpress and their Claims system. Question is, does anyone have a BMS recommendation for currently available 100-200amp 8S BMS? Wish...
