If you haven't seen it, BattleBorn just changed their warranty for a full 10 years on all their LiFePo batteries. This includes batteries that were already sold.
If you want to get the full charging speed out of these batteries, switch out your multi-stage converter for on that is designed for these batts. Progressive Dynamics sells a single stage converter that runs a constant 14.4 VDC charge (current tapers to zero when fully charged). But be warned. If you order the PD Converter from Amazon, there is only one seller. When I purchased mine from there, they shipped me a standard converter, and not the lithium version. And I had to pay the shipping to return it for a refund. I finally purchased mine from Best Converter for a fair price.
