42Ah 12V (12.8V) ECONOMY Lithium Iron Phosphate (LiFePO4) Smart Battery

The ECONOMY series of lithium batteries from MillerTech uses all of the same great battery technology with built-in BMS, safety precautions, matched lithium cells, and construction.  But to compete with low priced offerings from China and less reputable American sellers, the internal lithium cells used are Grade B cells.  This means that these batteries will have a few hundred cycles shorter life than the regular MillerTech line but are comparable to these cheap lithium batteries that are flooding the market.

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