Couldn't find its dimensions, with a lay down pipe, a small case format battery is helpful to find a place to locate it.
That feature where it goes to sleep mode and shuts down prior to over discharging could be nice with TL, might save destroying the battery.
Not having that issue though, the 480cca small case version lasts all day...
Should never run that low to even kick in that feature, so it will prolly be useless. One more thing to diag... imagining the issues that feature could cause lol.. help ski quites cranking right before it's fires and runs, could it the start stop or a ground. Or ski shuts down right as I launch from set up wake and I go over the bars, could it be a defective TL brain or a loose ground
I do like the big cca though... didn't list water toys as an application.
