I apologize. I'm not venting at you. I'm not frustrated. I'm over it. I just disagreed with your constant praises for Chargery and false (based on my personal experience) claim that they listen to customers and go out of their way to help their customers. I feel that it is a disservice to...

Just want to give an update to this horrible BMS. Hopefully this helps others stay away from this product. My 4 200ah batteries are now dead because of this useless product. My vehicle went in for service for 3 days. Batteries where full. Fridge and other appliances were running. Apparently...

https://electrodacus.com/SBMS0/SBMS0.pdf Not sure what you are looking to do, but the sbms0 can control an scc. They sell optional dssr20s but they are not required. I would contact them. The owner should get back to you. He is very knowledgeable .

Thanks Craig. Looks like that fixed the problem. I updated the update manual to highlight this important step.

Has anyone here used the electrodacus module? They are currently out of stock, but I'm seriously considering scraping this chargery stuff for their product. Too bad I was 1 month early on purchasing the chargery BMS before Will posted his review. I 100% agree with his findings plus poor support...

Am I the only one having problems? I have 4 of these units BMS8T. Just when I thought everything was good, problems started again. I performed the reset. recalibrated everything. Wh and Ah were showing up. I went to charge the batteries and two of the units turned off when it approached the HVD...

Fully charged batteries and still showing SOC of 0%

Hello Airtime, Thank you. I look forward to your review. Too bad they are sold out at the moment. I'm using 4 of the BMS8T, maybe that is why I might be experiencing higher than normal issues. At the moment, 1 of the 4 is giving me trouble.

Okay, I'm not sure what the deal is here, but I'm not able to set the Wh for the battery. It only lets me go negative values and not positive values. eg, only the down arrow works and not the up arrow on the display,

Hello Craig, Would you also be able to see if Jason can have the red "stop" button function better to turn off the BMS. Currently, the current draw needs to be 0A in order for the stop button to work. If there is any drift, it doesn't turn the bms off. This leaves the charge relays on and the...

Hello Craig, Here are my settings. Jason just told me that the problem is when my cell voltage diff goes above the setting value, it turns the discharge relay off. This is odd because it normally doesn't do that. Maybe my batteries are bad, but I constantly have been getting cell voltage...

Look at electrodacus and see if it fits your needs. Quality product

Hello, The SOC issue was confirmed by Jason to be a bug (I'm thinking this other cut off delay is another one). Jason also told me to wait for the new and improved v4 of the firmware (whenever that comes out and if it fixes these problems) Its been like that since I got them. Problem occurs...

Hello Craig, Thanks again. I tried the "NO" setting in order to prevent the random cycling of the discharge relay. The interesting thing is that my differentials, under load or heavy charging, go over 400mV and it never shuts the discharge relay. Maybe it randomly started working for one of the...

Thanks Craig. That may be the problem.

May Steve can talk to Jason at chargery. I suggested that maybe having a setting where the red button is held for 3s to force shut the BMS (and turn of the charge relay) could be an option. He says its illegal. But having a switch, with the delay board, to turn off the discharge at random is not...

I don't think so. Red going to battery side. When I have a big load (50A or more), I get a negative reading. When I'm charging, I get a positive reading. Now I'm not getting much of a reading since I have to calibrate it again.

The BMS started cycling the discharge relay again. Had to set "cut off delay time" to "NO" to get it to stop. I guess I am going to have to run the batteries down to see if LVD is triggered.

I'm not sure, like this?

Hello Airtime, Thanks, I'm confused though. when you say that you are setting SOC smaller than actual battery size, do you mean "battery capacity?" I see "SOC battery gauge" I set that to 0%. I have battery capacity set to 200.0AH. I (now) also set "cut-off delay time" to "NO" from the manual...

No loads that pull from the battery. The BMS is directly controlling the relays comming from the batteries. When the relays turn off, all power is disconnected from the vehicle. I haven't tried charging the batteries because I now need to drop the battery boxes to get to the cells. The BMS will...

You might have tested it momentarily. I have as well, it does disconnect when the voltage drops. For some reason, having the vehicle sitting for 3 days and no charging killed the batteries. ALL 4 of them. if you need pictures, I can post them here. In fact, when I return to the vehicle (in...

LVD was set to 2.9V.

2-3 days, but it was hot and the exhaust fan was running so it could have been shorter. I am just going to replace all the cells and bms units. I can't deal with all the quicks and issues with these units. BTW, the one bms unit which wouldn't save settings never worked right and never was able...

Hello Bob, I'll try updating the LCD software to see if that fixes it

I'll try charging them, but each one has a cell that is a ~1.9V

Here is what the display is showing now. Does this look right?

Anyone out there able to help me with random problems I'm having with the BMS8T. All of a sudden tonight, one of the BMS8T modules started cycling the discharge relay at 5Hz (the cut off delay time is set to 5S). The voltages where within limits (3.3V each cell x4) the temp was within range. The...

If you want to stick with this product. I'll have 3 for sale $50 shipped to cont US. next week when I removed them. BMS8T 300A purchased in the Summer from Jason. I also have the delay boards as well

Any pics you can post here of the burned Chargery unit?
