Hi All,
I've successfully setup my AC200MAX for 700w DC-DC charging for about $150 USD.
In my case it's from a 12V 560Ah Battery bank on my RV, but this is relevant to vehicles too, probably more so, I'm going to do the same in my car so when I leave the RV I'm topping up the AC200MAX when...
I would suggest using the Base.apk as this does not allow you to flash the wrong firmware, which is nice.
So you can try every flavour of firmware on here.
it will be a 309 type of firmware, as you have more than 6 strings
This manual suggests there are only 6 possible combinations...
Daly 12V 4S LifePo4 250A 560AH
Brand new here, the efforts in this forum to navigate the minefield of firmware update for the Daly BMS have helped me immensely.
I wanted to try a new firmware, as the version I had was not shutting off with my victron MPPT 100/15 solar controller, the bouncing...
Inside of the SMARTBMS2.4.3.apk there is only one firmware available. I'm not sure that the app downloads any other firmware.

From Google Translate, My german is 35 years ago....
"With a new installation or first start, my Daly BMS is always set to 3.7V as the maximum permissible voltage!
I then reduced it to 3.55V in my case!"
My BMS was set to 3.55V, but the bouncing nature of the MPPT voltage was inducing the BMS...
Thanks! I was surprised it didn't gather any more interest, as charging these stations while on the road seems to be the focus of many folks on here. I'm really interested in what we can do on the expansion battery terminal and if the expansion battery terminal will pass any current back.
Hi mate,
Have you tried to update the firmware and failed or is this a first use?
Also, list as much about your hardware as you can.
Voltage, strings, model number, current firmware number
Mine for example is Daly 12V 4S LifePo4 250A 560AH Boot Version:V1.01.1E which makes it 103 aka ST103 aka...
Ok, cool, original firmware.
Might be worth starting a new topic as I don't think your issue is related to the firmware auto update which caused this whole mess in this thread.
For info, your firmware is GD230, boot version V3.01.1E, identified by the first number (3) in the firmware.
I'm weird...
