By the way, let me translate what the 84x48 dot-matrix LCD above says, word-by-word:
At the 'Runtime.jpg':
-Line 1: 12.20 V
-Line 2: 64.8 m?
-Line 3: 135.8 A
...meaning:
-Line 1: 12.20 V
-Line 2: 64.8 mohm (m+Omega)
-Line 3: 135.8 A
And at the 'Runtime.jpg':
-Line 1:
-Line 2:
??
-Line 3:
??.
-Line 4:
: 1.05
-Line 5:
??
-Line 6: 22
?. 2017
...loosely meaning: Lead(-Acid) accumulator (=battery) Desulfator
-Line 1: Desulfator
-Line 2:[of] accumulators
-Line 3:(of) Lead(-Acid).
-Line 4: Version: 1.05
-Line 5: GeorgeKolovos (no White Space, due to LCD width limit)
-Line 6: Jul. 22, 2017
Makes any sense?
