I made them out of some Ollite's we had at the shop. Pressed them together, cut them and milled them flat. A friend milled them. I learned.

A piece of round stock cut to length with a hole drilled in it would be much easier but it was free. Or you could likely buy some from Mcmaster Carr.

I ended making a 3/4" spacer and buying new bolts. The bolts are 6mm x 45mm and were only a couple of bucks. I'm happy with the end result. I wanted to avoid the "Z" brackets and have a single connection.

whats the cable in the middle of the battery?

That's the Shorai Battery charger cable. I have it permanently hooked up in case I need to charge if it sits. I can charge it will the hood closed.

I read this battery requires about 14.4v to c
harge. The alternator puts out about this much when the headlights are turned on. Is there a way to have the alternator output this higher voltage when the headlights are off?

IIRC the alternator was putting out 14.5V at idle, assuming my meter is accurate. Or, the alternator was kicking in because the battery needed charging.


One month since install and zero issues. I accidentally left it for about a week without hooking up the charger and it still started no probs even though when tested I was down to 13.25V. Anything below 13V is supposed to be a problem...I got lucky. Duh...I forget it's there.

I have no head unit in the car. I'm not sure what that would draw when the car is turned off.

I've left my car for 8 days, came back, cranked no problem. I honestly think folks are overthinking it. I live in Texas and it regularly gets over 100 in my garage, so I seriously doubt anyone is going to encounter issues unless they just never drive the car. As long as its got a nominal voltage of around 12.8V or better it should crank, and your alternator should recharge the battery. To get back to peak nominal voltage takes about 20-30 minutes of driving.

Based on the way it cranks I would agree with you. Going back to "I forget it's there"

The problem isnít hot weather itís more cold weather. But the people who have problems typically live in colder weather and most likely have something that has a constant draw on the battery even when car is off like alarm system, remote start, parking dash cameras etc.. or they have a 5 minute commute and never fully recharge the battery. Otherwise for the most part yes you can forget about it and use like normal battery. Only time I hook up to charger is if itís sat for 5+days. If I know Iím not going to drive for 4+ days before hand I just unplug terminal, can sit for a year if it has zero draw. If I donít know like this winter on day 4 when I was planning on driving it snowed so on day 5 i hooked up to a charger. Otherwise I just forget about it. Off a full charge I started car 5 times in a row little to no idle and 5th start up still cranked harder then OEM battery on full charge.
