There was 3 dead battery and bought 9 secondhand batteries and changed rather 9 of them cos I mesaured that those are not right.I had 12000km in the old batteries and what I bought 9 they were only at 6000km.
I tried to make them at the same level by voltage to mine ones and put it in.
It worked good but I knew it needs time for the newer batteries to equalize.
I have used it for 1000km and was ok but not 100%.
I was using it and a month ago put it away due to weather.
So I remember when finished using it there was 3 bars and 17km range dispayed.
Ok left it like that but knew I need to charge it to something like 80% to make shure batteries will be ok to store.
Went today and wanted to charge it but there is a big problem as it starts ok but now it shows 10 bars and 0km.
I plug the charger and is starting but for only like 15sec and switch itself off like it`s got enough power in the batteries.I left it on for few hours and the bars gone down to 4 but when I plug it on charge it goes up to 10 bars again in few sec and swithes off.
What`s happening few cells are dead again or is it just really unbalanced?
Did someone have the same experience?
