I have 8 eg4 life power 4 batteries and they all have gone into the bms sleep. We are having trouble getting them out. We have parrelled another 48volt battery and still will not wake it up. Also have an eg4 charger hooked up to a generator to charge the batteries and will not kick on either. Need some guidance here. Thx Shelby
Eg4 life power4 battery won’t wake up

If it won't wake up all of them, disconnect them and charge them one at a time.
Yes we can communicate with our laptop. When charging it still reads zero on the bms software. Maybe the eg4 charger is not a compatible charger to wake it up?Can you communicate with the batteries using the BMS_Test software tool from EG4?

Looking at the picture of the battery stack it appears all battery breakers are off except for the third battery from the bottom of the stack. The SOC and Run lights are lit which indicates the BMS is awake and working.
Are you using the EG4 Charge-Inverter or some other charger?
Can you provide a wiring diagram of the batteries and how the charger is wired in as well as the charger settings you are using on the charger?
Can you also provide a screen shot of the BMS_Test software while monitoring the battery (see picture) as you try to charge it. In particular what is the the state of the "CMOS" indicator

I want to make sure that I am reading this right. Were new batteries added to the bank and then this happened or were all batteries present prior to this?
We did add 2 additional batteries and then a few days of no sun the batteries went to zero. The chargeverter is not working either. As soon as you flip the breaker on the battery the alarm comes on and the amperage goes to zero on the chargeverter.

Attached is the charger we are using. we tried connecting it right to the battery but it keeps on tripping the system still and reduces the charger to 0 Amps. This is an offgrid camp so I don’t have access to send anymore pictures as I am currently out there right now.

With the BMS_Test software (if you can communicate with a battery) will tell a great deal about the state of the battery including the individual cell voltages, any alarm conditions and the status of the Charge and Discharge MOSFETS.
What do you mean by "Tripping the system"?

As soon as you hit the breaker on the battery the alarm comes back on and the generator gets a load and the charger goes to zero charging amps. I will be back at camp Saturday and try to hook up the computer.

If the battery alarm is on then the BMS is probably turning off the Charge and Discharge MOSFETS. With the Charge MOSFET Off the charger has no where to send current so it would go to zero amps.
You need to use the BMS_Test software to connect to the battery to determine the issue.
Once you establish communications with the battery the software will tell you exactly (hopefully) what error is causing the alarm light to come on.
Once you can get the software to talk to the battery and hopefully tell you exactly what the alarm is then EG4 (@EG4_Jared) can work with you to solve the problem.
Once EG4 (@EG4_Jared) has an idea of the error they can help you with a remedy.
Screen shots of the BMS_Test software screen would be helpful.
Any distributor of the EG4 LifePower4 battery can supply you with the cable necessary to connect to your computer. If not I can help you to build a cable that will work.

We disconnected the batteries and tried one at a time from eg4 chargeverter. The setting are 56 volts and trying to push 10 amps. Each time we flip the battery on the generator receives the load and then the battery throws back on the alarm which won’t allow a charge to go through. Definitely frustrating.

There is another thread on this forum that may be of help including a pdf file of instructions provided by EG4

On this thread I explain how I made my cable for battery communications:

Cliff notes version:
Using the BMS_Test software select the "Config" tab. Enter 888888 as the password and the tab will populate with a number of controls. On the lower right "Reading and writing MOS adhesive fault codes" click the "Read" button. The "Value" should read 00. If not the pdf from the above link will explain.
I had a similar issue and first entered FF for the "Value" and clicked the "Set" button. I then entered 00 and clicked the "Set" button. Then click the "Read" button to very that 00 got set. Hopefully this will clear any alarms and the CMOS and DMOS will turn back on.
Anyone else with a recent EG4 48v Lifepower4 battery purchase getting a "Charging MOS fault alarm" that can't be reset?
Got my battery last week, but today was the 1st time to get a full charge on it. Everything was great @ 99.6%, cells balancing, current curtailed, but I had to leave. Got back about 1 1/2 hours later to the beeping & red light associated with the fault. Re-set didn't work & I couldn't find...

A couple of further questions would be whether the chargeverter is connected to a shared bus during this event, or if the battery is entirely isolated with the chargeverter attached directly to the battery terminals. Additionally, upon integrating new batteries into the system, I would check to see that each battery's voltage is within 0.5 volts of the others by conducting tests with a multimeter at the battery terminals while they are isolated.
We did hook the chargeverter directly to the battery so it was fully isolated. Loads up the generator and alarm comes back on. I am told from your support to now try to Jump with another 48v battery and use the chargeverter at the same time. Is this something you would advise to do?
the last fix is gonna be open up the battery and charge each cell individually to high enough for it to actually turn on
you can multimeter each cell and check what the actual voltage is which would be interesting to do at least
