G'day peoples,
A while ago, I built a beach cruiser.
Then, last February, I had the LiPo batts go up in flames, taking the bike with it.
Even melted the alloy wheel rim! It was hot!
After a total strip down, the frame wasn't damaged, although a lot of alloy brackets were melted away. It was a good feeling when I saw the frame wasn't badly damaged & my nads dropped out of my throat back to where they belong!
Anyway, the frame just needed minor repairs and a respray.
The panniers were totally destroyed & since they were made with a total loss mould technique, I couldn't easily reproduce them but I got some small motorcycle units on the 'net. All I had to do was paint & make the mounts for them.
And so, here it is, Eden3 resurrected.
Batteries are in the right hand pannier, under this cover.
The new battery is a 4S8P Li Ion pack built with Samsung cells with a BMS.

Nice to see a new bike arise from ashes of old, good way to start a new year. Like the new panniers!

Re: AussieRiders beach cruiser ressurected
Thanks for that fellas. Test rides show a lot less range since the new battery is treated a lot gentler. Both packs were / are 8S, 10Ah. The old LiPo pack gave me 24 km but I was abusing it, discharging to 3.0V per cell & charging to 4.2 V per cell with no BMS, thinking I knew what I was doing. This time, the Li_Ion pack with BMS that cuts out at 3.2 V per cell & charging to just 3.7 V per cell giving 10 Km range. I'll up the charge when I'm braver.
Any of you in Melbourne Australia, mark down February 18, 2018 for the EV expo & I hope to see you there!

FWIW, 3.7v/cell is on the almost-flat part of the curve, so you could be anywhere from close to empty, to barely half full, to getting towards full.

Re: AussieRiders beach cruiser ressurected
Thanks AW, you're quite right. The charger seems to be for 7s config, not 8s. If I can source a 32v Li-Ion charger, I'll be fine. Or, while the cells are still new, get 2 more & reconfigure the pack to 6p7s. Had to do this on the Industrial Mutant bike & found that 7 fully charged cells hold a lot more than 8 barely charged ones.
