In Brief: Shorai LFX19A4-BS12 Battery Review

If you are looking for an excellent motorcycle battery that will not die on you, then this is one of the best options on the market.

Shorai was founded in 2010, and it quickly became one of the best battery manufacturers.

Based on California, the company started producing these LFX batteries that are less than half the weight of lead-acid batteries. Plus, they last much longer.

The LFX19A4-BS12 is just one of a wide range of quality lithium batteries that are available in many different sizes.

Even though they are slightly more expensive, they still sell at a very competitive price for Shorai Power!

This Shorai LFX battery has a very slow discharge rate to allow it to hold its power for longer.

This means that there will be a much longer time between charges, and the battery will not lose its power easily.

Being compatible with the normal lead-acid battery charger allows for a much easier charge for this battery.

It is smaller than the standard lead-acid batteries, but it will still fit snugly in the battery compartment with the padding.

The padding that is included will help to make up for the reduced size, as well as help reduce vibrating. It is also very easy to use the padding, and it can be done with very little effort and time.

It is available in many different case sizes to be suitable for use on many different types of bikes.

You have a much higher power output with this battery, which provides you with a stronger cranking power for the engine.

How To Use The LFX19A4-BS12 Battery

  • When installing the Shorai LFX battery, please read the installation guide.
  • When removing the old battery, remove the negative cable first, then the positive cable.
  • Compare the old and new battery side by side to determine the size. The new LFX should not be larger than the old battery.
  • If the new LFX is shorter or smaller, use the spacer foam provided to make up the difference.
