Project Cappuccino: DIY Lithium Battery Installation

  • Dave Zipf
Shorai Battery & Bracketry Weight
Our new battery, strap, and terminals weigh 3 lbs, 3 oz. This has shaved 15 lbs from our Cappuccino. The Cappuccino is so light this is actually a 1% weight reduction.
Shorai Battery Installed
With everything prepared, we removed the OEM battery for good and set the Shroai battery into its new home. The new bracket safely secures the battery in all directions. The terminals are solid and corrosion resistant for years of use. The balance port is easy to reach for future charging. We can easily isolate the battery when needed and our terminals have plenty of room for jumper cables in an emergency.

Immediately we noticed the starter motor turned over a bit faster due to the higher cranking amps.  We’ve been running the Shorai battery since the summer and we are very happy with it.  After 1000 miles of street driving and autocrossing we have had zero issues with the battery or its mounting.  Our old failing battery would have trouble starting the Cappuccino after two weeks and would be totally dead within three.  The Shorai battery has no trouble firing up the Capp even after weeks of sitting.  Anyone could replicate our results with a little patience, planning, and some very light fabrication.

    Nice! I’ve had a Shorai in my CBR600rr for like a decade. OEM batteries died after 2-3 years each. The Shorai, even a decade old, cranks up super strong even after sitting for two months. I’ve never had to put a tender on it like I did the factory batteries and those still died after a couple years.

    Was the vice mounted metal bender you used fabricated or purchased? If purchased, may I ask where you got it? Thank you. Nice work on the Cappo. It’s probably my favorite build series on here.

      They’re called manual rod (or flat) benders. The one in the article specifically is a Huth manual rod bender. They run about $100.

      What Augustus said below is accurate. It’s a handy tool for bending rod or small flat stock.

      And thank you for the kind words, I love this little car and it’s currently getting some winter updates to the interior and cooling system.
