I have two maplin 6v 4.5ah batteries wired in series to power my dashcam while parked.
The batteries are similar to this one :

Will this split charge relay be ok to re-charge the batteries while driving?

Hi,how is the split charge device to be wired,and from where?
 
The 6v batteries will be right next to the car battery and wired similar to this:

The relay I have ordered is a Tec2 20a so it uses a 15a fuse and it has an extra "ign" connection to connect to a supply that is live when the car is switched on.

My main concern is how small the 6v batteries are in ah and physically.
These split charge relays are more commonly used to charge large leisure batteries.
