Hi @osman, welcome to the Community!

Unfortunately 36v configuration of Victron LFP batteries is not supported, so Victron LFP batteries will not be the solution for your particular application. For more information, you can see the datasheet available here

Individually charging 12V batteries in a string is not a good idea.

@osman it's not just a question of charging them, it's that they may not be used in that configuration. Certain Victron battery banks may be series-connected to 24 or 48V while others may not be series-connected at all, but 36v is not an option in any case. Victron batteries are not the solution for your particular installation, unfortunately.

Do you need 36V for some special application or you just happen to have three 12V batteries and want to use them all in one system?

12V, 24V and 48V systems are more common and Victron Energy gear is suited for these.
