You can see current from battery and current to motor in the “normal” overview/graphs, like in all common log viewers (metr/voyage/…). Do you need them per speed-bin as well? I personally don’t see the benefit there, the main purpose of that speed-bin view is to get an indication about efficiency vs speed.

Ok, also that would mainly be needed in the graph view, not the speed-bin view I guess… At the moment BREmote V2 only communicates with one VESC via UART… I will put 2 vesc readout on the to-do list. Until then I know for sure VESC Express (can buy that off AliExpress for 9 Euro) can log multiple VESCs at the same time. Althoug I find the usage of VESC Express rather finnicky and furstrating at times…

I also have recently included a feature, that will make measurement of remaining battery % (SOC) very accurate. To use this you have to configure the exact battery type (manufacturer and model).

I will prepare the most common cells for everyone to use.
For that I would be happy if you could respond with a few cell types that you think are most common in eFoil and boogie at the moment?

For sure I will do:

  • Sony VTC6
  • Samsung 30Q
  • Molicel P45B

Which other cells are a must?

My beta testers sadly are a bit slow testing :sleeping:
But I myself have tested it thoroughly and Jasmin already ordered PCBs for it, so it is coming soon!

You can have a look at the bulid video here already, files will be added to git soon as well.

When comparing prices the BAK and EVE cells are quite interesting as well.

Examples I could find on NKON:

  • EVE 40 P and PL
  • EVE 50 PL
  • BAK N21700CGP
  • BAK N21700-45D

I need the discharge curve :wink:

222

The above 50S seems to be a 50S2

The 50S2 can be identified by a “2” in the lower left corner of the printing on the wrap. If it’s not there then it’s the original 50S.

For the discharge curve, you have MOOCH:

… and the discharge curve of many other popular cells.

I didn’t realise what LUT was until I watched you explanation video in the “BREmote V2 - Open Source Remote” thread… what a useful and nicely built feature !
