Just saw an ad for 12V lithium battery packs (yawn), but something caught my eye. The company "GBS" is advertising that their LFP packs are noticeably smaller per watt-hour than the competition, and the only difference seems to be the addition of manganese (to increase energy density?). The element Mn is well-known from a few years ago, when LiMn battery packs were popular between the ancient Lead-Acid/NiMH era, and the modern Li-NCA/Li-NCM we use today.

Yes been a while, also "Powerizer".

Winston's also claimed benefits for their "special" Yttrium doping, e.g. lower temp tolerance.

Color me cynical, marketing differentiation? Never seen trusted testing confirmation of those claims.

But higher density can be objectively verified without risking destruction.
