Only five votes per forum user 
I am removing my other less priority votes, To vote on new ones
I think we need to create new feature request to increase no of votes and use one vote on it 
Also if there is an option to sort all the feature request on the number of votes forum users can see what other owners have voted the most
Don’t know the reason. What your odo? Many other 450 owners have faced Abrupt shutdown. My 450 charged only using fast charger from nov19 till mar20. Mar20 to jun20 not used. From june20 till now mar21 using dot home charger. I had to go from 100% to 0% many times when going long. These may or may not be the reason as other 450 owners also complain about this issue. Its better to ignore any charge left below 20% and plan to recharge when it hits 20%
