I'm sure Polaris wouldn't put it there if it was going to be a problem but spending my entire life (albeit 19 years) working with electricity, terminals out in the open like that just worry me. Anybody's $.02 on anything is appreciated as this is only my second bike
On both my 450 and 570 sportsman's I think its horrible placement. Within 6 months I've have to change mine. after the 4th on the 2018 450, I stopped buying the expensive $100.00+ batteries and now order a $40.00 one off of amazon. That one has been the longest lasting ones. The very first battery I had on the 2020 570 exploded. Yes, Exploded. I put a brandy new one in an cleaned up the mess, and it went out in a month. The battery case was actually cracking.
So I said self, These batteries are either pure junk or its the bike. I went and lined the battery boxes (for lack of a better term) with that black Gorilla tape on both bikes, and the problem seems to have gone away.
I ride these things through the Arizona desert and some of the river bottoms are so bumpy it knocks your feet clean off the pads. I don't know who though of this placement but your battery is out in the open for every rock, branch and bump out there sitting on a metal frame. The Gorilla tape gave it just enough padding so it quit beating itself to death. In all fairness to the bike mfg. I did catch my 15 yr old jumping the 450. he (not kidding) had it at least 10 ft. in the air. I was wondering why he always brought it back and something was broken. Apparently it was the thing to do with his friends.
