Hey guys, first post on forums here, so sorry if I got the wrong discussion. Does anyone know if V5 has a power expander like the current cortex and batterieis have? I know we can’t use the ones from this year, since the battery connection to the cortex will be different, or am I wrong?

[image] Barin: I remember reading somewhere that the new batteries definitely have higher capacity. And the correct metric to look at would be Watt-hours instead of milliamp-hours because the new batteries are 13V instead of 7V and no public information exists yet regarding the new system’s curr…

[image] tabor473: The motors are 2 - 2.5 as powerful as 393s. We can deduce most of that is just the different voltage and that they also run at a little higher current. Fair point.

The main difference is the battery technology and the discharge curve. The Cortex NiMH batteries might have had 3000mAh, but you never use the full capacity for a host of reasons. Voltage sag both due to discharge and load limits you to <20% of the nominal capacity of the NiMH cells (with charge sta…

Exactly what @nenik said is why there is no need for a new PE. Lithium batteries have a much higher and longer usable capacity than an equal size NiMH battery.

a lot of already answered questions about V5 are being asked again, I’m not blaming the people who are asking, it can be hard to find stuff on here, perhaps someone should compile everything Paul has said about V5 into one, easy to reference post.

If you go to youtube and search for V5 there are videos from multiple conventions. I would recommend looking at those. I am pretty sure I saw two batteries on one of the more recent videos.

[image] Easton: There is only one brain port for a battery, and since there is no v5 power expander the only way this is possible is for a robot to have two brains, which is not likely and definitely not competition legal [VEX EDR V5 System -- CES 2018 Preview] I believe the bloc…
