This product review will go over the quality, installation, fitment, and function of a Shorai battery.
The Shorai battery is an ideal solution when looking to swap out a heavy OEM battery to a much lighter weight saving alternative. These batteries are lithium based. Which means they can hold a charge for a long time while also charging very rapidly. Shorai batteries come in a number of sizes which changes based on the cranking amps. If you are looking to shave every last ounce of weight from your car, Shorai offers batteries that weigh less than 4lbs! Since the batteries take advantage of lithium technology, you will need a battery charger specific to the Shorai batteries.
When it comes to batteries, what is inside is what matters the most. Shorai uses modern lithium technology in their batteries. Lithium tech is very reliable and provides excellent cranking power. There is also no liquid in the battery, like you might find on traditional or OEM batteries. Because there is no liquid, this allows Shorai batteries to be very lightweight. In addition, you do not have to worry about battery acid leaking from the battery. The Shorai battery comes in a durable plastic case with attachments for terminals of your choice. I have personally used a Shorai battery in 2 different cars over 3 years. Both during the cold of winter and the heat of summer. The battery has yet to fail and continues to crank well in the winter time. The saying “you get what you pay for” is very applicable when it comes to Shorai batteries.
Installation of a Shorai battery will depend largely on the vehicle you are installing it on and the kind of mount you have. For my Scion FRS and Subaru BRZ, I have a mount from Kinetic custom machine (no longer in business). This mount is made specifically for my Shorai LFX24L3-BS12. There are also many alternatives and even a number of DIY (do-it-yourself) options available. Once you have the mount, the installation process is very simple. If you can change a tire on your car, then you will likely be able to change out the OEM battery for a Shorai battery. In most cases, it is just a matter of removing a couple of wing nuts and tie down arms and then replacing them with the appropriate mount and bolts.
Fitment for the Shorai battery is going to depend entirely on the mount that you choose. For my mount, the fitment was better than stock. The KCM mount fits the Shorai better and holds it into place more securely than the OEM solution.
From a functionality standpoint, the Shorai delivers. In most cases, you can get improved cranking power compared to your OEM battery. They work well in both warm and cold conditions alike. Probably the most important benefit is again, the weight savings. With my Subaru BRZ OEM battery weighing in at nearly 30lbs, the Shorai battery is eliminating 25lbs of weight by coming in at 5lbs or less! If you are looking for other lightweight BRZ or FRS upgrades, consider a Tanabe Concept G exhaust or something similar.
The Shorai battery line up gets a 5 star rating because of their extremely lightweight, compact size, powerful cranking options, and ease of maintenance.
Shorai battery rating : 5 out of 5 stars
