Nice video.

I'm about to finish up my 20s pack, debating on how I want to the the battery charge/discharge cables. I think I might go with AMASS AS150 connectors.... They come in packs of 4 individual 1 wire connectors, 2 male, 2 female... with 1 male being anti spark. Because of this, I was just going to use a single Anti spark (male) connector on the battery's positive, and then as required, 1 for each of the charge and discharge negative connections on/from the BMS. Was originally gonna use XT150's since i have 3 colors of them... and only 2 of the AS150, but the AS150 not only has the anti spark functionality, but is also a little bit bigger, spec for slightly higher current.

Anyway, just trying to decide on what Gender to put on everything. The male Anti spark is the obvious one... in which case, if I wanted to have the same gender for both on the charger, I would have to go female. THO, having different gender on it would make it basically impossible to wire backwards... but it's also easy enough to differentiate red from black. And I suppose depending on whether I decide to go both the same gender on the charger or not, would lead to a decision on what to use on the negative discharge cable. And I already know the positive on both the charger and the controller at least have to be female if the common positive on the battery is the anti spark male. I suppose if both the charge and discharge negative connections are the same gender... it could lead to confusion, being the same color... BUT that's also easy enough to solve with a piece of colored electrical tape or something... and one thing to consider is... would it even matter if the negative cable form the charger was accidentally hooked up to negative discharge cable from the BMS/battery pack.

Anyone got a common technique on this one.. I suppose if you're used to using 2 pin connectors, like the XT90, it's a ltitle different than using single wire connectors and eliminating the need for 2 different wires being connected to the positive end of the battery.

I like idiotproof solutions. Those connectors..... you can't fail even being drunk.
Xt90 and andersons are my fav.

A good point and I do have a bunch of XT-90-S (anti spark)... But I'm gonna see if there's a setup with them and still be completely idiot proof. If not , I'll probably go with the XT-90-S, which was my original plan... till I got a good deal on 5 sets of AS150s. I'd prefer to use the AS150's tho, that way there will only be 1 wire to/from the positive side of the battery pack, won't need to split/splice a second wire in.
