The 3rd generation of Honda Fits (2015-2020) have notoriously small OEM batteries at a mere 340 CCA (cold cranking amps). This will often be problematic in the cold temperatures and your car won't start if you haven't driven it for a while. The default size is 151R.

Please do yourself a favor and upgrade the battery to a 51R size with 450 CCA and you shouldn't have a dead battery problems anymore! You also shouldn't need to modify anything to fit the larger battery under the hood.
