I finally got my slightly used 570 midsize. Traded in my 570 Sportsman with 140 miles for my midsize with 145 miles. Now, for the build and additions. The original Polaris battery seems to work well but might be to small with future add-ons so I want to add second battery under the driver seat and wire in parallel. Question: Can I use a larger AGM boat cranking battery as the second battery without damaging the electronics? Don't knoe the amps of the original stock battery but the second battery is much bigger.
