Well, it goes there :slight_smile: Just be careful not to short those two… Are you planning to use firefly Controller?

104

Sn%C3%ADmka It is way easier to put it in here, as there is nothing to short

105

Awesome, thank you very much. I have a GT2B transmitter, no firefly.

106

@solidgeek @matiller You could ask himself :smile:, coz I don’t really know a solution for that

107

Thanks @Pryside for this build, been watching your YouTube videos, learning lots! Looking to do my first build this month :slight_smile:

Can I use 57v power supply with that smart bms? (12s)

109

I watched your You Tube video a few times and you went into detail on alot. I want to know how you might change your board if you are using hub motors Would you still recomend doing a 12s 2p system? or less power because the motors don’t have to turn a gear.

110

@matiller no!

111

@curtis his battery is a 12s3p and will work with hubs perfectly fine as well. Don’t go 12s2p.

112

well… can I use 52? or what is the safe voltage? Does it have to be 50.4 or can it be 51? Thanks

113

Get a charge which fit to your battery 12s battery means 12s Charger. You probably will not have issues if you use a charger with lower voltage besides that it will never charge up 100%, but don’t use a charger with higher output voltage than your pack. A smart bms is not a wonder box. It’s still just a bms.

The bms might save you from blowing up your battery but the only save way to charge it is to get a “50,2V 12S charger”. There are a ton of them on aliexpress

What size nickel stips did you use? As I am reading 10mm by 0.15 is not enough… Thanks

116

depending on how many cells paralell you have. If the current only has to go less than 20mm there wont be any problems. Otherwise just weld another sheet on top if you want to cross a bigger distance

Hi @Pryside,

  1. Can I use this ESC instead? It’s cheaper https:///collections/esc-speed-controller/products/torque-esc-bldc-electronic-speed-controller

  2. I understand that you don’t recommend TorqueBoard motors. What motor do you recommend?

  3. Is the belt 265mm or 280mm ?

  4. I have a drone with a 6S 4in1 ESC, does installing a TVS diode help protecting the esc?

  5. There is always a spark when plugging in the battery. Drone is powered through the ESC board. Should I also install anti spark?

118
  1. Many on this forum use that ESC, should be fine, but will require the diode trick if you intend to run it at 12s voltage
  2. TB motors have been updated recently to make them stronger and more reliable, I don’t see why you wouldn’t go with them
  3. belt length depends on the pulleys and mounts used, someone might know a good calculator for it
  4. don’t know
  5. sparks when plugging in a battery is normal, most people here use loop keys as switches instead of anti-spark ones.

Just received the first PCBs I made of my precharge Antispark. Will solder them and do some intensive testing next week this should be very nice. 20

I have a few more questions. Thank you in advance!

  1. Isn’t it better to print the battery/VESC case with TPU instead? It’s more durable and it can flex when the board flexes.

  2. I already have a 1000W 12V server PSU. Should I get a voltage booster like below and rely on BMS to balance charge the battery pack? https://www.amazon.com/dp/B00E8D7XYG/?coliid=I3MVENO2EUVXXT&colid=2NAX0GX2GD9J1&psc=0&ref_=lv_ov_lig_dp_it

  3. Do I need to buy LONGBOARD SHOCKPAD RISERS 3MM ? https:///products/longboard-shockpad-risers-3mm?variant=712549924887&gt

123
  1. No. Solder joints, nickel welded batterys and in general all pcbs dont like flex. You can split up the battery into smaller parts and spread them across the board and have them connected with some silicone wire but you will run into ton of loose connections if you print this thing in tpu and ride it for a while.
  2. yes that works. I used a Boost Converter from ebay (300W 80V boost converter) to charge my old board with. But these days I perfer to have a small power brick with 90W (12S Liion charger) from aliexpress with me so I can charge wherever I go and dont have to think if Its worth carrying this brick.
  3. You can but they only protect your deck and dont have any ride quality improvements since you will squish them anyway when screwing them in. Ride quality only gets improved by softer and bigger wheels and a softer deck
