This one I was repairing the original controller/screen went together and mounted to the chassis like a sandwich. This new one has 4 mounting holes in completely different positions and had no way for me to mount the screen since the previous one had standoffs coming off the controller that mounted it. I was able to make it work by drilling/tapping new mounts to the chassis and partially disassemble the new controller "sandwich", use some shorter screws and nylon spacers to make my own standoffs for the screen. Was a lot of unnecessary work for a controller swap. That really is unprofessional working practice - I can live with them changing the boards themselves, but altering the mountings now is just making repairs needlessly protracted and difficult. Big minus points to Begode from me there, and I'm normally quite forgiving of them. 2 Quote Link to comment Share on other sites More sharing options...

chanman Posted February 2, 2023 Share Posted February 2, 2023 (edited) Seems fine, double ended battery connectors seem kinda janky but if they work and handle the current they're supposed to I guess no real problems... until you crash the thing.

Cerbera Posted February 2, 2023 Share Posted February 2, 2023 Yeah I guess if he truly does intend to use it as cruiser it'll probably work great. Good use of remainder parts. He might have to resist tackling those mental slopes he seems magnetically attracted to, and doing those risky biscuits bump and jump manoeuvres, lest his extended boxes dig in, and not being metal, split or crack, but if he can stay away from those, or otherwise protect those at-risk undersides it seems like a very simple and solid solution. He's obviously got riding stamina way in excess of mine. I'm knackered after about 30 miles or 1 charge meter bar off max on a Standard Master !

Satellite board went straight in there no problem, but charge board but was a right royal pain in the arse ! Begode had unhelpfully gunked the allen sockets in 2 out of 3 of the hex bolts holding it down, making getting those out a slow, painful and gradual process. Then tried to loosen my motherboard screws, but that was stuck down hard to the base by other means, and I didn't want to disconnect everything going to it so I tried to extract the old board around it, which took some time because of those massive capacitors being in the way, and squeeze the new one into the space. Got it stuck several times, but patient finagling won the day in the end, and eventually it went in, and seated OK. Damn awkward to get to those battery connectors with fingers - you almost have to do it by wiggling on the wires - I did not enjoy this process ! And I thought I had done it wrong when I didn't get any pop at all when I reconnected MB to charge board. But, no, she powered on fine, and balanced, my display and lights worked at -2 degrees C, and she is charging now, with no immediate signs of the magic smoke, so I think that went OK. Here's the bottom of the old board... versus the bottom the new one... Looks like we have slightly better soldering (except maybe that one pad above the top right brass spacer), and conformal coating everywhere on the new board, as opposed to just the battery connectors on the old one, and considerably more complex / populated layout. I got a pop when I reconnected. Quote Link to comment Share on other sites More sharing options...

Yeah so did everyone else apparently, which of course makes me suspicious about mine, even though it has done 250 km and 3 charges without issue since the board swap... I did discharge the caps before swapping the boards, so I really was expecting a pop that never came !

Wouldn’t this dislodge whatever thermal pad is underneath and did you recalibrate after? Quote Link to comment Share on other sites More sharing options...

Don't think it matters that much, you angle it upwards a bit and then it gets hard pressed down by the screws again, I didn't recalibrate, angle seems alright but might be a good idea.

EUCzero Posted February 4, 2023 Share Posted February 4, 2023 Are we all supposed to change the charge board? And why? I thought charging was controlled by the BMSs in the battery packs, and not the battery connector board (charge board). Or is there some kind of balancing in this board as well?

You should check to see if you have the new charge board. The new chargeboards have an extended connector for the controller. The older chargeboards have the connector on the chargeboard itself.

EUCzero Posted February 4, 2023 Share Posted February 4, 2023 Thanks for the info on how to recognize the new vs old board. I do not have the new one. But I am still wondering what the difference will be as balancing should be in the BMS and not in this board. So what is going on there that I do not know of?

I don't remember but I think I read that it might have to do with the chargeboard not charging the batteries to 134.4v. Not exactly sure though.

I can't explain why but from what I understand old chargeboards creates imbalance in packs. Quote Link to comment Share on other sites More sharing options...
Lilvodka Posted February 9, 2023 Share Posted February 9, 2023 We had people with the old charge board here and the moment they tried to fast charge it the fuse in the charge board blew, maybe this is the issue?

Don’t quote me on this 😂 I blew a fuse on the new chargeboard with my hypercharger. I believe it was my fault as I didn't 100% make sure to turn the amperage dial down... Thankfully the batteries and the hypercharger are fine. Quote Link to comment Share on other sites More sharing options...
Cerbera Posted February 9, 2023 Share Posted February 9, 2023 Since my new charge board was installed I have been seeing better final charge voltages almost every time I do it. Last week we were up from 133.2v to 133.9, and today we tipped over into the 134's, which might be expected if the balancing was improving...

Kutvis Posted February 14, 2023 Share Posted February 14, 2023 (edited) Sounds familiar to anyone? Newest mobo, I rode from 100% to 0%, got 67km. Charged and it felt like it dropped to 50% almost immediately. Charged again.. to rouhghly to 97%.. got around 30km.. I quess 1 battery pack is lost. The wheel "BUZZZ" when shut down. E: Removed all batteries from mobo and discharged it, buzzing continues. Comes from battery pack. E: 500km untill V2 mobo mosfets got blown + 256km to that untill the battery pack failed. Master buzz.mp4 Edited February 14, 2023 by Kutvelo 2 Quote Link to comment Share on other sites More sharing options...
EUCzero Posted February 15, 2023 Share Posted February 15, 2023 Yes. That is the battery BMS. Not necessarily bad battery, but BMS has shut it down for some reason. Contact your dealer. Quote Link to comment Share on other sites More sharing options...
