... on BMS with common charge and discharge port, the discharge current has to flow through two banks of Mosfet's, whereas on BMS with separte ports for controller (P-) and charger (C-), the discharge current just has to flow through one bank. This means they can reduce the number of Mosfet's on the bank for the charge port which would explain the lower price.

common port:
pros: usually identical max allowed charge and discharge currents, protection against overcharge from regen (or charge via controller)
cons: more heat at given discharge current

separte port:
pros: less heat a given discharge current
cons: usually lower max allowed charge current, no protection against overcharge from regen
Thanks for the succinct explanation!

So, last week I got my frame kit and today I just got the 200A SPIM08HP packs, I test fitted them and even though I pre measured everything before buying the batts I was still a bit nervous they weren't going to fit but check the pictures out, im glad to get them in with space to spare for the BMS, of course its no 36Ah pack, its only 8Ah but I think its going to be a super fast build, I can now take my time sourcing and building a 240 cells 30Q pack.

Next step is to paint my frame and rims before starting the build, pictures when done...

Started building the parallel packs (have not put them in series yet) :

I'll probably have to double every nickel strip, especially those in series. Kweld works great btw

This may seem like an odd question but it is important for my particular use-case:
  • Can you discharge (i.e. power some load) while charging with a "common port" type of BMS?
(I'm 99% certain you can with a "separate port" type)

Any updates on the battery pack build?

Not really, I can only work on it a few hours during weekends and I'm waiting for the BMS to be delivered.

Here's a pic :

This side is finished since then. I still have to do the other side.
I doubled every series connection.
I purposely left some space on the top right corner in order to have some space to fit some electronics, maybe the BMS if it fits.

That is a LOT of spot welding. I'm glad I got a proper tool

Damn, didn’t think the sink was going to be an issue with the lacing, no biggie, I’ll remove it, lace it and place it again.

And about the paint, well plastidip is not meant to be permanent, just a super easy way to paint over what you already got and super easy to remove and repair, under tge plastidip I still have the original black/white powdercoat.

Was too late for me. Missed that you are using dip.
I like dip but have no experience. But lacing a wheel with spokes I wonder if it will last without scratches.

Let me know how it ends + pics. =)

Battery almost finished, can someone please tell me I didn't screw up cable management for the BMS ? It was really a pain... I now have high and low spots and I intend to use the same solution as Offroader

I have yet to solder the power cables and I'll shrink wrap everything

You have to check the voltages of the wires to make sure the BMS wires are correct. They should rise about 4 volts each successive wire or how much your voltage is.

Why do you mean high and low spots?

Yes voltage is correct. By high and low spots I mean that the sides are not completely flat anymore and vibrations could make some cables rub against each other. I saw you put some foam in some places in order to prevent that

Test fit.

Putting the BMS inside is going to be fun, although there's room.

Very nice Mallory, call your build "offroader II" thats a lot of battery. I like it.
