The Mini PRO is under warranty
You put it in charge 24 hours
It is possible that the charger has gone into safety mode, so during its charging, it has micro-cuts.
So the charge will be very slow.
After one night, the battery will have received enough charge,
and normally the Mini and the charger could resume their normal cycle
The Mini PRO is not under warranty
If you have electrical knowledge
Check battery voltage
if the volatge is between 42 and 45V, it's possible to try this :
The Mini Pro are now too old to sell.
They came out in November 2015, then there were others made in June 2016, if the batteries are over a year old, without being recharged, they do not turn on anymore.
Mini Pro buyers in France and the United States testify that they can not turn on the Mini PRO.
Do not buy Mini PROs that have been stored for too long
Last week I saw a Mini Pro in a shop, it has not moved for a year, the tires are deflated, I imagine that the battery has never been recharged
But a Mini Pro buyer import from China has not had this problem, more recent manufactured in 2017 (see pictures below).
Since they were activated in China before being sent, they are therefore in working condition
Ask the seller the production date, tell him it's because of the batteries.
There is a sticker on the cardboard, the year appears.
If it's 2016: do not buy it
Thanks to More4Mini

A while scared, but fortunately there were no other large vehicles around. . ."
