2025 R3 Charging System Specs/Potential Issues

[DesertRat]

1) Does anyone know how the Voltage Regulator circuit in the 2025 R3 Alternator is set to., (i.e. At what Battery Voltage is set to disconnect/limits the charging circuit to the Battery).
2) Has anyone determined the Parasitic Power Draw of the Bike's Electronic Systems, (when the Bike is sitting, Engine Off)?

While doing some preliminary numbers, I don't think Triumph spec'd a large enough battery to simultaneous supply all the Electronics on the Bike.

The Triumph R3 OEM Yuasa 12V AGM Battery is spec'd at 12.8VDC at 18Ah.
That's a NEW 12V AGM Battery @ 100% performance, (no degradation of age of Battery, or degradation due to High or Low Ambient Temps factored in).

Triumph spec's the required minimum Battery Voltage of greater than 12.6V.

That leaves a VERY LITTLE margin for Battery reserves <2VDC.

I can now see why a lot of R3 Owners have Electrical Systems Malfunction(s) created by a poor performing Battery.

Anyone else like to opine?? Feel free.

If they'd spec'd the bike from the get go with a LIPO battery things would be fine, but changing from the AGM to LIPO has it's drawbacks with a system set up for AGM. I just leave mine on a tender & will replace the AGM with like when the time comes. The tender also negates any parasitic draw, so there's that too.

Install a wifi battery meter and you can see exactly what charging system is doing and you can see parasitic draw from rfid remote stuff and other things drawing. Over time you will see when battery degrades. My cranking voltage has been low after this past winter when battery froze and cut off, i had in storage and it took a hit, no charge 6 months and frozen at some point, but it lives.

I'm with Kiwicol on this one. The charging system is not built to fully charge a LIPO battery and sticking it on a tender maintains optimum voltage. Oddly my Speed Triple came from the factory with a LIPO battery so I have to have a tender with that option to keep it charged all winter.

Do you know what the estimated Parasitic Draw is.

I'd like to work with a few other calculations.

Thx

I dont, sorry.

If you like math here you go, the formula for determining final nuclear reactor power after adding a positive reactivity amount: P (power) sub 1 (Final) = P (power) sub 0 (Initial) times the natural log raised to t (in seconds) over Tau (Reactor period).

Hey Mr Atom,

With all those Bike,s

Can I be added onto your Last Will and Testament???
