Just a single 6.5mm hole in the panel and two wires across your
on-board battery supply. Developed specifically for use with 12V
Sealed Lead Acid/Gel Cell batteries in the range 7-18 Ahr. Notably,
the three thresholds (for Green, Yellow & Red) have been preset
for batteries which are NOT used while connected to a charger.
