MillerTech 50Ah 12V SPRINTR Lithium Iron Phosphate (LiFePO4) Battery (1250SP)

The SPRINTR series of lithium batteries from MillerTech make use of carefully matched Grade B lithium cells with a premium battery management system to give you the same great performance of their PREMIUM batteries but with a lower price tag.  These batteries feature the same internal construction, safety measures, and electronics, including a new on/off switch on top of the battery and a new, full-color LED fuel gauge to show you the state of charge of the battery at a glance.

SPRINTR batteries are the successor to the ECONOMY series that MillerTech previously offered and have the technology and low price to compete with the flood of cheap, low-quality lithium batteries on Amazon and Ebay from Chinese companies you have never heard of.  MillerTech is an American company from Ohio with a well established reputation, an excellent warranty that they stand by 100%, and customer service and technical support that answer the phone during business hours right here in America!

This SPRINTR series carries a full 3 year warranty that covers everything except abuse or misuse.  MillerTech will replace or repair the battery at their cost and discretion.
