Hey Chaps.... reading the thread with interest.
I have been looking at the Jump bike removable batteries. They are a pretty good size and rated at 36V so I was looking at what it would take to wire 2 of these together to make a 72V pack to power a 72V ebike build. I will attach a photo as I don't see much info on them on the forum (I know this is not exactly a scooter.. but oh well To view images REGISTER or LOGIN for full access.
From what I have read the built in BMS's on each of these may have a shit fit if you try to wire them together... so have any of you built a higher voltage pack and how did you handle charging it? Is there a way to retain the stock BMS's somehow, or would I need to scrap them and figure out something else?
I am also looking at wiring 2 x the M365 packs together to make an 84V pack to act as a supplementary battery for a Kobalt 80V electric chainsaw. It has an 80V battery but it is only good for about 15minutes of moderate use.
Same issue... I am a novice with the battery/BMS stuff and would love some guidance on how to wire these up and how to charge them... could I use two bird chargers still or would I need to get an 84V charger?
Could anyone recommend a good source of education on this stuff on Youtube. There are a lot of idiots on there... I need someone that is good at explaining this stuff and really knows their sht. Please share your findings... and of course I will post my results when I get something worth sharing. To view images REGISTER or LOGIN for full access.
