It is safe to run parallel lead acid batteries like this. It is preferred that the batteries are all similar in terms of rated capacity and age/health. Mixing say, a low Ah and a high Ah battery in parallel, will cause the low Ah battery to discharge at a higher "c-rate" than the high Ah battery, which will tend to age that battery faster.
