Lithium iron phosphate is gaining a lot of ground in the battery market, and for very good reason. They last longer, are more efficient, and damage the environment far less than lead-acid, and even the highly touted lithium-ion varieties. As such, you'll find a massive range of uses for this relatively modern cell. Solar systems, for example, are very well-served, especially by units like the Renogy, which is proving immensely popular for home use. Alternately, the Bienno is an excellent choice for on-the-go use, as it features a built-in converter, and a female AC jack that accepts plugs from a number of different countries. The Waterblade and EarthX both feature exceptional construction quality, and are well-suited to devices that might get wet or dirty, like dirt bikes, snowmobiles, and the like. Shorai makes a long line of LFP options, and we've highlighted one of the most common sizes, popular in a number of Yamaha bikes. Just be certain before purchasing that you've found the right size for your application, and remember, if it's a touch too small, that's ok — Shorai sends along some foam shims to achieve a perfect fit, while also reducing vibration and increasing safety. If you need a classically shaped, cylindrical battery, Westinghouse and HyperPS both make great ones, but again, your correct selection will be determined by your specific devices. Whatever you do, do not use a 14500-cell as a direct replacement for a AA battery. They have over double the voltage output of a standard 1.5-volt, AA cell, and will quite possibly explode and damage your device beyond repair.
