I did electronics measurement and battery drain calculation for rocket3R 2022 - Battery, Turn signals

Hello All,

Hope it helps someone

- Stock blinkers are 2watts 12V LED Array in each blinker/turn signal so they are consuming 167Milliamps per blinker.
- When bike is completely OFF and Key Fob is ON and in range then motorcycle drains battery at 80Milliamps.
- When bike is completely OFF and Key Fob is OFF, then motorcycle drains battery at 5 Milliamps.
- Battery on Rocket3R2020+ is 12V 18.9Ah.

Based on numbers above, here is battery discharge duration assuming battery is at 95% efficiency ( Battery at normal temperature etc )

Approximately 160 hours ( 7 days ) to battery drain/low battery/low voltage battery - "When bike is completely OFF and Key Fob is ON and in range then battery drain rate is 80mA."
Approximately 2880 hours ( 120 days ) to battery drain/low battery/low voltage battery - "When bike is completely OFF and Key Fob is OFF then battery drain rate is 5 mA."

Your bike has a problem. Not a bike I have.

I put a battery logger on my bike and here is some info. Battery is 9 months old, stock, as came from the factory in my bike. The bike's FOB switch is on always, never found it to be an issue.

So, an example of a few weeks between riding:

I rode my bike on Aug 17th. Then the very next ride was Sep 2nd. Hey, I was on vacay, k? The voltage on Sep 2nd was 12.74V (before I rode it). To compare, the settled voltage on the next day from Aug 17th (which is 18th) was 12.84V. So, it dropped only 0.1V.

measured on 2 different bikes, one was in my house and other one was in Australia, so 2 bikes have problems for last 2 years?

Perhaps your measuring is flawed.

measuring simple current current consumption between battery and a load with $1000 fluke multimeter is flawed, got it?
tell me a flawless way then?
