My opinion is that low current fuses on the panel (or behind it) are
more likely to cause problems than prevent them. I use just one fuse
per battery circuit. I prefer a 10 amp automotive blade fuse mounted
at the battery. If it might be of interest, I've prepared a short
treatise on glider battery wiring and fusing including a picture which
is accessed at this page:
