Split relay charging

Hi All
I got some useful advice on here for linking up the starter batteries to the leisure battery so that the starter can be topped up from the connected solar panel and also so that the leisure can be charged from the alternator.

It states that this kit is suitable for batteries ranging from 75ah to 220ah - however the two starter batteries are rated at 70ah each - could this lead to potential problems/dangers?

Thanks in advance

Can't see a problem but send them a message to see what they say too.
