This is embarrassing. It appears you are correct. A few minutes after I posted this thread, my replacement battery arrived. That's for the one that puffed out (story from my other post). I removed the not-so-puffed battery and replaced it. Charged the pack, and BMS came back to life. Sorry to...

Thank you svetz and A.Justice for the response. I definitely see what you mean. My main does loop back to the Load OUT when that switch is flipped on that diagram. Thank you both. I'll get that appropriate switch, or do two switches. We'll see.

My LiFepo4 setup is 8 cells of 3.2V on a 12V connection with a 4S Daly BMS. It was top balanced, so they all go up at 3.6, pack voltage of 14.4V. I happily charge them using my benchtop power supply everytime they go low ( made it a habit of charging them back up once they hit 12.6V ) as I dont...

I hear you. Thank you. I have my revised diagram. Is this any better? This now allows my to manually choose between getting power from the Load OUT of the ATS, or from public power right? Thanks again for your inputs.

Thank you again for all the responses. Snoobler, thanks for the gel pack setting suggestion, I'll take note of that and will try it out once my solar panel is ready. Thank you ampster, good to know good to know that someone had an experience with batteries that aren't that good anymore. Thanks...

Hello again guys. I have 8 x 3.2V used sinopoly batteries 90AH each, and just got a brand new set of 8 x 3.2V 120 AH batteries, both Lifepo4. I am thinking of using them both under the same mppt charge controller, and at the same time, connected to the same inverter. I am thinking of 1st...

Thanks for this GXMnow. Is there a way to "insulate" my mouse from that noise the power strip is emitting?

Hello, Good day and happy Thanksgiving to those in the US. I need some help / guidance on my recent Daly BMS purchase. I purchased it from Aliexpress. Its an 8S 200A common port Daly BMS. Its connected to a 24V pack, and I am using a cheap 2000W continuous / 4000W peak 24DC-220AC inverter. I...

Thanks Snoobler. To be clear, I charge the batteries in series to up to 3.3v since thats the highest that they still balance, then put them in series, set the PS to 3.65v and charge all the way until they hit 3.65v? I can do that. That would be very tedious though if i have to do it everytime...

Thanks for the responses. After reading the manual, which seems to be a rough translation from Chinese ( very sketchy and hard to understand ), it seems to be the sensor for the mppt temparature. I might still be wrong though, but I think l'll keep it this way for now. Thanks again.

Just the info I needed. Thank you snoobler To describe my situation, I have a bank of 8 120ah lifepo4 in 24v connected to a 60a mppt charge controller fed by 4 x 370w panels. I have another mppt scc at 40a sitting here collecting dust. I am thinking of the following: 1. Upgrading my battery...

Hello, Good day folks. I am seeking your help and expertise regarding extending the temperature sensor of a mppt solar charge controller. This is the mppt that I bought. As you can see, the temperature senson is there, but its just too short. It have to be right next to my battery if I am to...

Thank you so much for this snoobler. This got me into reading mode and you are right. I have been doing math for this all along like I have a lead acid battery. Thank you. As for my batteries charge rate, its .33C for the 90AH batt bank, and .6C for the 120AH batt bank. I am right at the limit...

It looks like I am in the same boat. I was in the process of preparing to top balance my 120ah cells. Noticed that one of the cells has its positive terminal thread is loose. Was not using studs. I have studs now to replace the screws. So I drilled the positive post to widen it and insert a...

Hello, Good day to you all. I am a newbie about solar energy, as well as on electronics. Thanks to google and YT, I am closer to completing my setup. I do have some questions though, and I thank you in advance for any responses. If I have anything wrong in my setup, your critiques are much...

You are much welcome Ampster. Glad I was able to help a bit. Just sharing my observation though. This cheapo inverter of mine worked fined. Didn't cause any issues to my laptop. Laptop is the only load. Then I connected a 6-gang extension cord as I was planning to add another laptop: I...

Hello @snoobler , just a follow up question. My 120Ah battery bank has a 200A BMS. Planning to add one too for the 90Ah BMS then get both banks in parallel like what you recommended. Is it necessary to get the same 200A BMS for 90Ah bank? Can I go lower like 100A for cost saving? Thanks again.

I have been using a pack of 8 120ah Higee lifepo4 batteries in series 24v config for a little over a year now. I wanted to increase my pack capacity and so just recently, I acquired a new set of 8 of the same battery. My questions are: 1. Now that I have 16 pcs of the same 120ah Higee lifepo4...

Hello guys, I'll be moving to a new house soon, and I am planning to build a solar system utilizing 24v batteries to power most, not all, of my foreseen daily loads (24in LED TV @45w, 2 laptops rated at 135w and 60w, 2 fans assuming 60w each, a washing machine @ 420w, an induction cooktop @...

Hello, Good day. I need your opinions/suggestions/critiques about my plan to install a Moes automatic transfer switch. I am planning to use one for my house. I have drawn up a crude diagram or schematic on how I plan to wire it up. Please see the picture below. Please forgive my crude...

I have also thought about this. But is it correct that by putting them in parallel, 1st bank of used, aged sinoply at 2304 Wh at best, and 2nd bank of bnew aluminum cased batts at 3072Wh would mean I also need to increase my solar panel array? Right now I have 2 x 370W panels that I think is...
