Xiaoxiang Bms, Carplonge Bms app. In RV. Today I was checking my electrical system for a trip. Everything was working, then all of a sudden everything shut down. It seems my Solar controller crapped out, not 100% positive yet but I am leaving tomorrow. So I put a spare on and everything is back...

I have seen 17 amps on ocassion. Now its been in the garage only powering a phone. Maybe tomorrow Ill back it out and power on the AC for a load to see how each controller does. Howerever 1-2 amps more to change to a MMPT I dont think its worth it. I bought a 20A Sunthsys by mistake then...

I cant get it now I broke my foot a couple days ago. I watched it. Yes I get it but Im still better off with that odd panel than only 200W. If I can fit a bigger pannel in its place since its bigger than the 100w ones I will upgrade later. thanks

Yes, 280W of solar and 280A of batterys. The MMPT is a SUNTHYSIS 30A. The panels are in parallel. 2 are 100w Monocrystalline 1 is an older 80w Polycrystalline.

I bought this controller off Amazon a couple years ago for my RV with 280A of solar and 280A Lifepo4 batteries. Its working fine but recently there is speculation that its a PWM, since there is no inductors in it. So I thought if I went to a real MMPT one I might gain a couple more amps. I...

Yes I did all that However I loaded another app Overkill as suggeted and it worked. The I went back to the caplounger app and reads correct now. The xiaoxiangBMS App doesnt work at all. I cant find the blutooth. I like caplounger better because I can set all the parameters and cant with...

I already set the capacity at 280A but it stops at 180A and the cells are not full about 2/3 or more. Id I set the capacity to 180A it reads 90A. available

Thanks for your answer. This is what I ordered in 2021 How can I tell if its JBD? Dykbcells Smart BMS 4S 150A 12V LiFePO4 Li-ion Lithium Battery Protection Board W Balance Bluetooth APP high-Power Temperature Protection 3.2V 3.7V Battery Pack (4S LiFePO4 150A) I already downloaded those apps...

Im using a Xiaoxiang 150A BMS on my 280A Lifepo4 Battery consisting of 4 cells. I have been using this for about a year. Today I was putting on a new mmpt solar controller and noticed that the app im using said the battery had 179.8A. In 1 year I never noticed it was not reading 280A. It always...

In case anyone is interested, I found the problem. With my BMS you must attach the B- to the battery before you connect the C-. I built up a 81650 pack to play around and I found the solution.

I was looking for something like that but could not find anything. Although the day before the lights came on and the charger worked proper, it was only after I tried the Air condition and disembled everything to find the problem, this problem started. Yes I suspected something hooked back wrong...

Yesterday I went to my MH to check out everything prior to a trip. Everything has been working for a while. I have a 4s Lipo4 battery and 150a smart bms, charged through a 280A alternator and Renology 60A DC2DC. The MH had been sitting for a couple months plugged in with a charger on the...

Yes top balanced when I installed them. I set the BMS to 14.6 and the Renalgy to Lifepo4. However when I charge with a 10A battery charger set to Lifepo4 which I did today. This is what I got when the BMS kicked out. 3.523, 3.441, 3.590, 3.597 This as after I tightened all connections. So after...
