1st Build, ATB, Parts, Sources, Pricing, Calcs, etc

Hello eSk8 peeps :slight_smile:

1st post. Been lurking for a few days learning. Thanks for all the great info.

I have compiled the data for my 1st build. Figured it would be wise to run it past the community to see if there are any glaring mistakes I made.

Let me know what you think…

Gonna build the battery pack and box

Power system is over rated for the estimated amperage even at full throttle. But my choices were a mix of commonly used components (figure they must be quality) and price point.

Full BOM (w/ Pricing & Sources):

everything looks good, except few things I would like to mention:

I’d rather go with charge only bms from some reliable source, like Bestech (few of us had problems with them lately, but they are still considered reliable) or Daly red bms from aliexpress. I wouldn’t trust some random high current ebay bms with discharge.

Flipsky motors had some quality control problems before, loose magnets and such. I would pay a little bit more money for some 100% reliable motors.

for on/off, I would go with xt90s loop key. @Deckoz had awesome solution with AS150 connector, it looks slick and its bulletproof (xt90s is too). It seems he deleted his post so maybe ask him in private?

don’t forget to order female bullet connectors for vesc-motors connection

nice, thank you.

do you have a suggestion on the motors? trampa motors seem quite over priced, as nice as they may be. any other options?

I’ll ping @Deckoz regarding his loopkey setup.

I appreciate the help

edit: I see the principle idea now for the loop key. this looks very fault proof. good call.
