Here's an idea for a small pocket meter that will measure voltage & battery capacity on Dorado Shark, Hailong, Pedego and other batteries that use a 4 prong spade connector.
My bikes all have volt meters which is great when the battery is in the bike. I have 3 bikes which I store in an unheated garage and a total of 7 batteries which I keep in my shop. Installing a battery in the bike just to check it's voltage isn't practical.
I usually do a check 3 or 4 times during the off season and adjust the charge level if necessary for proper storage. I got tired of getting out a voltmeter and connecting the leads every time I wanted to take a reading. Last year, I built this little gauge which just plugs into the battery without even removing it from the shelf. I can check all 7 batteries in less than 10 seconds using just one hand.
These are the required parts:
Gauge:
Connector:
Epoxy:
Bond the connector to the back of the gauge with the JB Weld plastic epoxy:
Solder the leads observing the correct polarity:
Although it isn't necessary, I encapsulated the connectors with more epoxy to protect the wiring:
To read voltage, insert into any battery that uses a 4 prong spade connector observing the proper polarity:
I added a flat vinyl cap to keep the prongs from damaging other items in a pocket or other storage container.
The project cost around $25 and took about an hour to put together. I realize it isn't useful for everyone. Many of us are in the off season now so I thought I'd post in case the idea helps someone.
