I have the following problem: I have a 12.8V LiFePO4 Battery that powers the circuit and a lead acid charger with Intelligent MCU Control of 12V and 1.5 A to charge the battery. When the battery is charging, the load is taking current partly from the battery and partly from the charger, putting the battery in a state of constantly discharging and charging. If I understand correctly this is not good for the battery as it lowers the capacity in the long term.
When I connect the load directly to the charger it provides enough current.
The goal is to prevent the load from taking current from the battery while the battery is charging. I created this circuit as a possible solution and would like to know if it could work, or is there a better way, maybe an existing component, a BMS, or other solution?
I also found this BMS (VE.BUS BMS 8-70 V) but dont know if it serves the purpose, or/and is an overkill.
Any help is very much appreciated.
