I think im going to order a bms from here. https://www.lithiumbatterypcb.com/product/3s-li-ion-or-4s-lifepo4-12v-bluetooth-smart-bms-with-100a-120a-150a-constant-current-for-power-conveter-12-6v/ I have always used these guys. They offer a 300 Amp 4s with heating function in it as well as low...

I have a 190 watt onboard panel and a controller. I do plan on putting the controller in lithium mode. That should get the rest of it charged up. How should i set the charger cut off voltage to on a battery thats going to be connected to a charger all of its life?

I actually just canceled the order. So im looking for another bms. Which way should i go? With the single non seperate charge and discharge circuit?
