P500 2nd battery

[ScottA58]

For those running a 2nd battery in a new 520, what battery did you buy? Just got a call from my dealer that my 2025 520 has shipped from Honda. I want to order my second battery know so I can start my build as soon as the 520 arrives.

TIA

I had an extra lawnmower battery so I used it. Works well so far.

I already have the dual battery isolator kit, I am just asking for feedback on what battery others have purchased as their second battery.

Motobatt MBTX30 (AGM, fully sealed, 12V, 450 CCA). This is the largest capacity battery that I could fit under the hood of my P500. Requires a custom battery box. All accessories are powered from this second battery - winch, auxiliary light, air horn, power steering).
