Re: Soyachips’ Electric FZR250

What did you end up doing with the coolant inside the frame? Just leave it empty? Interesting place to store coolant I reckon... I just left it empty, yeah I was pretty surprised to find that! I thought about cutting off the tubes that come off the frame where the hose attached but since I'm avoidi...

I should be able to ship the buslinks and PCB over to you by the end of this week.

If you're interested in more A123 cells, I have around 80 or so in my shed
Thanks Matt, good to know in case I need to replace some cells or increase capacity :D

Re: Soyachips’ Electric FZR250

Also I've managed to get some A123 20Ah cells to upgrade my battery pack. These looks like pretty amazing cells compared to the Headways so I'm really looking forward to getting these in the bike and seeing how they go. I built some cardboard boxes to try out different configurations and although I ...

Re: Soyachips’ Electric FZR250

I recently added a brake lever to the bike to control the amount of regenerative braking to use. Previously I was just using the percentage setting in the Kelly controller to control the amount but it was either just right at lower speeds and not enough at higher speeds or vice versa. This way I can...

Re: Soyachips’ Electric FZR250

Any recommendations? I went with Headway’s because LiFePO4 are meant to be safe and they’re easy to assemble.

Re: Soyachips’ Electric FZR250

Thanks! Having lots of fun. Still things to sort out but at least I can have a bit of fun in between fixing/improving things. My biggest constraint is range which at the moment is only 25km. The 10Ah cells I bought on eBay and the 15Ah cells I got second hand. I’m not even sure if the 10Ah cells are...

Re: Soyachips’ Electric FZR250

OK so it's been a while, again! The bike has now been registered for about 3 weeks and I'm having a lot of fun on it. Now that I'm getting to do longer rides, I'm finding new issues that I'll need to work through but overall I'm really happy with the way it's turned out. Will now start saving up for...

Re: Soyachips’ Electric FZR250

After the last lot of testing there was a fair bit of work to do getting ready for brake testing and inspection. Replace dead battery cells, wire in the emergency cutoff switch, replace oil in forks and add spacers, etc so after all that the bike pretty much looks the same but a lot has happened! La...

Re: Soyachips’ Electric FZR250

Well done! Very smooth and quiet. Did you end up sealing the battery pack with silicone or something? You must be stoked :) Yes very happy with the way it all went except that I need to replace one of the cell groups so once I’ve got the replacement cells I’ll rebuild the pack (again!) with silicon...

Re: Soyachips’ Electric FZR250

OK it’s been a while again so there are a few updates. The EV Expo was great to be part of. Lots of interesting conversations with people and great to see all the other conversions people have done. I didn’t quite manage to get it running for the show but it was all together at least. It didn’t take...

Looking for a few 15ah and 10ah cells to replace some bad ones. Does anyone have any they’re willing to part with?

Thanks!

Re: Soyachips’ Electric FZR250

Thanks, looking forward to working out speed and range too. This will be my commuter to work so I don’t need it to go super fast, as long as the acceleration is good and I can get around comfortably without worrying about the range it should be good. I’m hoping the 6kW motor will be enough as I was ...

Grounding shielding around motor cable

The cables that comes out of my hub motor have shielding around them and someone recently said I should ground the shielding to the bike frame. Is this correct and are there any tricks to doing this?

Re: My latest battery build

Thanks @coulomb, I’m using the 72V Satiator charger from Grin Technologies so will check with them if this will be an issue or not. Also need to consider what happens when a cell hits HVC and then drops down as I don’t think the BMS has a latching relay. More food for thought :D

Re: Soyachips’ Electric FZR250

I'm trying to get the bike ready to show at EV Expo in Sydney this weekend so got some more work done yesterday. Made a plate to mount a waterproof box to hold things like 12V battery, contactor, fuse and other bits and pieces. Most of the high voltage stuff is in and wired up so its mostly the 12V ...

Re: Soyachips’ Electric FZR250

The certifying engineer suggested I use something to isolate vibration from the frame to the batteries so I'm using a couple of sway bar bushes that the original engine mounting bolts will go through to hold the box.

Re: My latest battery build

So I guess the charger realises the pack is no longer connected and stops charging? The charger I have doesn’t come with an enable line so I’m planning on using a relay that has 12V DC on one side and 240V AC on the other to turn off the charger if any cell goes too high. Can you see any issues with...

Re: Brendon_m Moke

I meant this but on closer inspection it looks like it might just be a connector or where the wires go into the controller

Re: Brendon_m Moke

Nice Tetris skills!

On the left around the smaller cables is a thingy like those ferrite beads on monitor cables. Is that to stop EMI from the controller interfering with something? What’s it around?
