Re: battery state of charge meters! Whats best??
The analogue meters draw very little and LED meter draws next to nothing ... You would have to connect about 60 of them to draw 1 amp.
I have had the test meter hard wired to a cart for 8 months out in 15 inches of rain and sleet and heat.... without so much as a hick-up. It is water proof and reverse polarity protected. No relay needed, just connect to the batteries or through the key switch.
