We recommend battery charger that support lithium battery charging. And to fully charge the battery, the DC charging voltage should be between 14.2V~14.6V, and charging current less than 200A (for 12V 200Ah Plus battery).
If you need to charge 2 batteries separately, you may need 2 chargers.
You could also connect the batteries in parallel first, and then you could use one charger to charge the two connected batteries.
It is okay for your generator to charge the LiFePO4 12V 100Ah battery without a battery charger, and you only need to connect rectifier between the generator and the battery to charge if your generator provides alternative charging current.
A rectifier allows the alternative current (AC) of your generator becoming direct current (DC) and to charge the LiFePO4 battery.
