I have been back and forth with Enginer a fair amount over the past few days. I asked for the balancers and they said they'd send them, but wouldn't warranty damage done from the 4 balancer setup. IMO this is pretty poor business practice. Their website specifically says the kit comes with 4 balancers. Only after ordering do they say you only get two and must use this new setup. Even if this buddy cell setup is superior, at least update the website guys! So, I am going with the buddy cell setup. The other day I started wiring it up that way. However, I came to find that they did not send enough extra connectors to even wire the pack in the buddy cell setup. I had to make 8 more connectors out of 1/2" copper pipe to finish the pack. Not a huge pain in the butt, but at least give me the parts I need to build the dang kit! I don't want to bash Enginer and I really want this kit to work, but this is getting more ridiculous by the day.
