I did this and it started working again!

Will said in a post the way to reset the BMS is to short the P- and B- ----------------------- Will: It's a daly. Usually need to reset them by shorting out the P- and B-. It will turn it out and you will have full voltage. As long as your balance lead is attached correctly. So take the P-...

I did exactly that: 1 - 3.283 2 - 6.55 3 - 9.83 4 - 13.10

With the BMS hooked up correctly, current will not flow through it. Is this a sign that the BMS is malfunctioning?

Daly 4S 12V 200A

I doubt no more than 20 Amps total at one time. The Daly BMS that I installed with the battery is rated at 200 Amps. Pretty much overkill, it looks like. But since I had no idea how to determine the rating, I figured better too much than not enough. I think also maybe I had in mind the...

How do I test a BMS if it actually is working or not? If it is without defect, how do I reset it to get it passing current again?

How do I know what Amp rating to get for a BMS? Solar Charge Controller - 30 amps Battery - 12 V LiFePo4 4 cell 200Ahr Solar Panels - 2 100 W

3) How do I reset the BMS?

1) Is there any way to test the BMS to see if it's bad? 2) My battery is 200 Amp Hrs -- Does my BMS have to be 200 Amps to use with my battery? Or is that overkill?

I'm not sure unplugging the BMS and plugging it back in is the way to reset the BMS. Is there a different way to do this?

Cell Voltages: 1 - 3.284 2 - 3.274 3 - 3.275 4 - 3.273 All 4 cells: 13.1 New battery, never used. I've never balanced the battery. Don't know how to do that.Could that be a problem? Maybe the BMS is bad, is there a way to test it?

I've already tried a reset that didn't work.

What does dmm stand for? Can I get one on Amazon?

Excuse my ignorance, but what are balance leads?

yes. I've checked the voltage of each cell and they are all nearly exactly the same.

The battery still has a full charge, but nothing works because the BMS has disconnected the battery. How do I troubleshoot the BMS? It disconnected after only a few minutes of use, on a nice day, for no obvious reason. The only thing that was on was the overhead fan.

What is the balance lead plug? (please excuse my ignorance -- still learning)

I bought the Daly 80 A-200A BMS (new) for my system, to be sure it was compatible with the LifePo4 12V 200 aH battery I bought from the same manufacturer -- "BLS Battery Official Store". I built my system and tested it out and everything worked perfect. Since we weren't yet ready to take our...

I have a BLS 4S LiFePo4 12V 200 AH Battery, with the EPever MPPT controller. Are the settings the same for my battery as with the Battle Born? If not what should they be?

This relay is for the inverter... This solution doesn't address disconnecting the panels from SSC in case the battery gets disconnected from the SSC to avoid damage to the SSC, What kind of relay should be used to disconnect the Panels from the SCC (an NO?) and how is it hooked up?

I have the EPEVER MPPT Tracer4210an (40Amp). I am using 6 gauge wire for the whole board. The manual says that the Battery wire size specified is 16mm2/6AWG. I have 2 100Watt panels that came with 8AWG wire. Will it overheat or hurt the MPPT if I use 8 gauge wire from the panels to the MPPT?

Is the DC-DC charger negative wire tied to the P- or that terminal in the center between the B- and the P- terminals on the BSM? If the DC-DC charger negative goes to the P-, then what is the middle terminal (without a wire) for? I've looked at the schematic on their site I'm still in a bit of...

There is a terminal in between the B- and the P- but it's not labeled nor is there a cable that came with it.So I guess I'll have to assume that that is the C- terminal that goes to the DC-DC charger and make up a cable for it. Am I on the right track?

I have a Daly BMS 200A. I know the B- goes to the negative terminal of the battery, but not sure where the P- goes. Do I connect it to my negative bus bar? That would supply a negative to all the loads... There is a terminal in the middle, which I assume is what is called the C-. I'm going to...

I have a Renogy 20A DC-DC charger. I've got a teardrop trailer that we plan to pull with our SUV. I'm considering mounting the charger in my SUV and wiring it up to the round connector that goes to the trailer. Is this the best place to mount the DC-DC charger? Also are there any other...

They are Renogy RNG-100D-SS

I guess everyone has seen this question: Should I wire my panels in series or parallel? I have 2 12V 100W panels and a 12V 200Ah LiFePo4 battery. The Solar charge controller is a 40 amp MPPT. What is the best way to hook them up?

I haven't actually built it yet. I've just done all the research to find all the materials I'm going to need, following Will's instructions on "The Minimalist Solar Package", but going with a 12V 200 Ah LFP battery (trying to take all the security cautions, correct gauge wires etc).

So what do you do to keep it from beeping when you run the inverter?

The BMS is to protect the battery isn't it? I don't understand what you mean by "protect the system". (please excuse my ignorance, I'm a first timer and learning everything as I go)

The BMS which will be wired directly to the battery has an over-discharge protection doesn't it? Here's what the Ad says: Overview ◆DL8S24V80A/100A/200A PCB is used for 8 series 24V lifepo4 battery pack. ◆We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc...

How do I know if the MPPT manages the entire load output?

The MPPT doc says it has over-discharge protection. Do you still need a battery protect module to keep it from over-discharging?

I bought the DC-DC battery charger (20A) by Renogy that Will recommended. I suppose it's only to be used for charging the battery when the car's engine is running. I have an mppt for the solar panels...
