Dragonfly Energy™ Lithium-ion Batteries

Take Your Camping Experience to the next level

Dragonfly Energy's legendary heated Lithium-ion batteries are now available as factory-installed equipment on most 2023 models, exclusively on any Keystone RV. Dragonfly batteries significantly outperform legacy lead-acid batteries with more than double the power in the same physical space, 100% depth of discharge, 5x faster charging, up to 10x longer life, all at roughly 1/5 of the weight. Because of Lithium-ion batteries' steady discharge rate, owners will get better performance from thier SolarFlex systems and avoid low voltage errors. Known for its popular Battle Born brand, all Dragonfly Energy batteries purchased as original equipment will include a groundbreaking 10-year warranty, a dedicated technical support number, and an end-of-life return and recycling program.
