I tried to order a torque arm and Anderson connectors from ebikekit. The order was $38.40 and they wanted $38.39 for shipping! no thanks.
Got the ampedbike torque arm and the Anderson connectors from Newark electronics. I think I have ordered everything I need. Except the celllog, they are on backorder.
Don't get screwed buy them here

As for charging; if you use an automatic SLA charger it will charge several packs at the same time. I have charged 4 lifepo4 12v packs at the same time and it worked great for a long long time. And every pack had exactly the same voltage when the charger turned off. The individual cell voltage was always good too. I am not recommending doing it this way I am only telling you I did it for a long time and I continue to do it this way. And for me and a lot of others it works extreamly well. However, even though I don't have any automatic monitoring I think it is alwas a good idea. But I am not talking about a BMS that in my opinion is over kill and has a lot of it's own problems. As I said I think to setup at triple 12v pack for series and parellal you need 12 or 14 Anderson connectors. 6 red and 6 black and that includes the charger too. But I always oder spares so I buy 50 at a time. And for sure you need the crimper tool.
