Overkill BMS - settings and cutoff protections check

Please let me know if I got my settings right for optimal use , 12v 4s 280ah

Looks good to me.

What voltage will you be charging the battery to? Looks like you will be charging at less than 14.6 volts.

I have no idea I just plug the battery in to my RV and the charger , solar charge controller, shore power connections charge it up.

I copied these settings from someone else with a similar setup that’s why I came here to check to make sure it’s all good

You need to set your solar charge controller and line voltage charger up to work with your BMS settings.
I set my SCC and line voltage charger to operate just below the BMS thresholds.

I checked my user manuals for both the solar charge controller and the progressive dynamics converter and I don’t think either one of them are programmable

Unless I’m missing something ?

I attached photos

I don’t understand these settings can someone explain a little ? I want my batteries to charge up to the highest point possible while maximizing longevity but also usability

Settings look fine. The charging and maintenance voltages of both the solar and converter seem fine while in use. Probably best to disconnect for storage.

The Over Current is the factory setting at 130 amps is set to protect the BMS from over current. Will disconnect if current excess for 10 seconds and reconnect after 32 seconds. This will give a few seconds of surge performance without damaging the BMS.

Awesome, I was confused about what you meant that I would be charging to less than 14.6 volts. I thought maybe the settings I had copied were too conservative.

The reduced cycle capacity and the cell full value seemed to imply your charging voltage might be a bit lower. So I was looking at the balance start voltage same as the cell full voltage and was wondering if your actual charging voltage would be high enough to trigger cell balancing. All is good at 14.4 volts.

Thanks for the help

Question why is my cell full voltage only 3.4 ? I can raise to 3.6 no?

If you click on the ? next to the setting, the setting is explained. I would leave it alone.
