Is it possible to pair two Bluetooth modules to communicate between a stock FW controller and a stock VLCD5 display? Want to cut down wiring.

Just posting this for comment - in the early stages of design at the moment but any feed back is appreciated. Images attached are of a 3D printed 4S enclosure.

I am trying to keep the number of soldering points on each cell to a minimum. Is there any reason why connecting the 18650 cells in this zig-zag pattern won't work? 14s4p arrangement - connected with 4mm tinned copper braid rated at 30amps. Cells are all hot glued together.

Hi Punx0r - maximum current draw will be circa 20A for a 1000W motor. If I've got my head around this correctly then I suppose that averages out to 5amps per tab. Roughly any idea what current can be drawn through the nickel strips?

Thanks for the response eTrike - appreciate the comments and suggestions. :)

Interesting and helpful information from everyone. Just looking at building my first pack 14S4P. I intended to use the factory tagged 18650 cells from nkon as these seem a great option. Would there be an issue using Z-tags and soldering up the 14 cells in series, and then bridging over between...

Okay - fist stab at a design for my battery pack... Please correct me if anything seems wrong. Going to go for 14S4P design using the Samsung INR18650-25R 2500mAh - rated at 20A continuous discharge. Should have a nominal voltage of 50.4V and 10Ah capacity - giving me approximately 30 minutes...

Thank you for all the comments - rather new to this so reading through various posts on the forum as well. I am based in the UK. The controller is linked here...

Hi to everyone - I hope people can offer me some advice. I am looking at what options there maybe for a 48v power pack – the controller I have is rated 48v to 60v and the wheel is a 1000w. I have quite a bit of experience with electronics and I'd be reasonably confident making up my own pack...
