I bought my RM480e - Roobi Riding Lawnmower in 2017 & this year I have to charge my mower between cuts. It has 52 hours on the meter. It runs less than an hour now.
So, it is time to change out the batteries. I found a YouTube how to change the batteries. I wish there was more information out there.
The cost of 4 batteries were $1023. Last year the cost of my battery on the push mower- EGO was $265. I am thinking this is not worth the cost any longer.
