I have a PC680 and its fine when its over 30-40out. Got it form batterymart.com for like $89 there something like $99 now. Last winter when I was SI after sitting a month I’d have to put a jumper box on it. Its was fine once it warm out and all year, even with the cam now. And when I was running a about 12.3:1 CR setup with big cam.
edit
damn $121… you can get them with a metal liner to if you if its gona be near heat. The PN has a addition on the end for the metal liner model.
Odyssey PC680MJ $138.11
PC680 here also. Stock location, made a small aluminum bracket to hold it down. Way easier to pass tech inspection, than having a sealed box in the trunk.
No problem,
I kinda passed the NMCA guys, Their the real deal. I’m making a simple alum strap this winter, thats better. But that pic is hows its been for 2 years, all stock tray stuff.
Go to car quest and buy a Deka battery, they are the ones that make the braille batteries. the ex14 is the smaller one and I had the ex20 the “all season lightweight” it weighs about 15lbs.
here was my ex20 installed:
the ex20 is a bit bigger, so watch the battery tray sizes if you buy one.
