Deltran (of Battery Tender fame) has introduced an LifeP04 battery. No affiliation - just looking for a new batt for the Tiger 1050 at some point.

The guys in the nerdy Advrider battery thread seem to like the EarthX line, which has an internal management system. Just looking into those as well.
Warranty is pro-rated three year: 100% year one, 50% year two, 35% year three. EarthX is two year 100%. Shorai is 100% six months, 75% months 7-12, 50% year two, 25% year three. They've extended the three year warranty to all prior sales.
For want of better measure.
EarthX ETX18C 230 CCA is $220.
Deltran 300 CCA is also $220.
Deltran 230 CCA is $149.
Shorai 270 CCA is $189.
Not sure if this is introductory pricing: Shorai's intro was not without problems. The early failure rate for a brand like Deka is .3%.
