Solution is, add some solar. It will gently charge your batteries to full, whether you cruise regularly or not, and maintain them. If you fit enough watts,it will power(or help power) things like 12v fridges during daytime. It`s not hard to do, and the cost will be repaid in battery life and available amps.
