Hi All
So this is my first ever Post, Not even sure if I'm doing right or in the right place
So Background, I just purchased a Ninebot es4 from an Auction, It wasn't going but I thought I might have a go at getting it going .
Turns out the external battery pack was loose so the docking port was worn and the battery wasn't charging .
So I removed it and charged the internal battery with a makeshift charger and it went ..Yay happy days.
This was short lived however as in my impatience to scoot around I think I have shorted out the BMS through too higher charging voltage .
Does anybody have any experience in replacing the fuse on the BMS ?
I saw one post on a German eBay site where they were selling a fuse rated at 25 amp and said it would replace all 3 fuses on the BMS

however my BMS fuse, the one in the top part which I think is the charging part looks to be a 5Amp fuse from the label, does anybody have any experience in this? or know its rating or a suitable replacement?
I know I could buy a new BMS for around $40 and $50 for the external Battery BMS but I'm Sure I could get the fuses for around $10
I will mention that the Scooter still runs fine, it just doesn't charge.

any help would be greatly appreciated
Cheers Matt
