Need some help for a DC to DC trickle charge

[Toddwmac]

Greetings;

I'm in the process of adding solar charging to a remote garage where I store some motorcycles. However, while I'm waiting on some permits, I was wondering if I could use a deep cycle battery to provide a small trickle charge to the bikes. (2-3 batteries) Just an .75 amp or so is plenty. Is there a relatively simple way to do this or do I need a Sterling (or similar) unit?

Thanks!
