Hello, I am definitely new to designing power packs and I have a couple of questions.
I was planning on getting a bms for a 4s LiFePo4 battery pack. Each battery is a EVE 304Ah. I was thinking about getting a 100 balance 40A bms. I have multiple sources of power this will be in a camper and I will have power from either the alternator, a 12v power supply (from hookup power), and 12v from solar power. I believe that the battery has a voltage of 14v (batteries in series). Will I need a battery charger for this or will the bms take an input of 12v and output 14v (3.5v per cell)? If I do need a battery charger is there any that have an input of 12v and an output of 14v? Or can I disregard a battery charger and use voltage step-up boards (20A) for each source to boost voltage? Or can the BMS do all of this. I want to be safe and make sure I am doing this properly. If I do need a battery charger please let me know if you have any suggestions for this setup. Thank you guys in advance.
