Hailong ebike Battery Voltmeter Holder
If you need to know the voltage of your ebike battery even when the battery is not plugged in your bike and you don’t want to use a multimeter every time to check, this is maybe for you. Because I don’t want to charge my ebike battery every time to 100% I need to know the voltage before I charge the battery by a timer (approx. 30min/1 voltage).
You need:
this holder: printed in PLA, about 4 surface layers, infill about 15%
voltmeter, this one is waterproof and up to 100V: DC4V-100V Waterproof Digital Voltmeter 2-Wire LED Display Voltage Meter for Automotive Battery Monitoring
2 ring terminal crimp connectors with hole about 3mm for the plus and minus wire
2 small plywood screws, about 3x12mm, not to long, screws should not contact each other
two pieces of aluminum or metal sheet, about 1.2-1.5mm thick, 22mm long and 6mm wide
2 small cable ties
Instructions:
the hole in the sheet aluminum/metal contacts can be drilled in place. Insert them into the slots and drill a 2mm hole into it.
check for polarity on your battery. They are also marked on the 3D model
with the two small zip ties attach the cables firmly
I did not cut the long cable yet. But you can if you never want to change it
