    curious why you use 7S and not 6S @jehugarcia

    Brilliantly executed friend fit, finish, and overall design killed it. I’m 3yrs behind no way I’ve seen them all. Betting this is still setting the bar. (ツ)ᕗ

    Confused. Your saying that each module is 400 watt. Is that right? Also in another video, you said to use the 2nd fuse on the oposit end of the positive standoff to have two positive connections on the power boards. Also how many BMS boards at 60amp is used on 25X kit, are you using a larger BMS? You might want to update the Video.

    Where can i get this kit..🙏

    Hay. The pins on the bottom of the SMC holders can be used for homing the component. Why not add through holes on the bord that will allow for this.

    It is also generally not a good idea to apply solder to a component, and then resolder to another surface. This is because Flux in the core of the solder would have already been used up for the amount of solder present. for this kind of setup, it would be better to apply some flux to the bord before reflow.

    Finally, you state that the back of the bord is not electrified. However, the silk screen on the back has a + near the pad. Is this a mistake in the silk screen, or is it actually electrified?

    Whats the difference between high power and regular ? Thanks.

  7. Avataaar/Circle Created with python_avatars William Vaughan says:

    I want the high power boards what is it just longer standoffs? I'm ready to buy All I see is the 1p 7s boards and standoffs. you show the 2p 7s setup that's perfect for me.

    Are your circuit boards open source if so could you provide a link. I have the bms file looking for the battery board file. Thank you in advance and HAPPY HOLIDAYS, or MERRY CHRISTMAS..
