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 premium MillerTech line (1200 cycles vs 2000 cycles) 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.
