9 Fastest-Growing Battery Technology Stocks to Buy

7. Dragonfly Energy Holdings Corp. (NASDAQ:DFLI)

Dragonfly Energy Holdings Corp. (NASDAQ:DFLI) is one of the fastest-growing battery technology stocks to buy.

On March 16, 2026, the company reported preliminary fourth-quarter and full-year 2025 results alongside a broader restructuring plan aimed at speeding its path to profitability. Full-year revenue rose 16% to $58.6 million, driven by 34% growth in OEM sales to $36.9 million, while gross margin improved to 19.3% from 13.1% in 2024. The company also said it cut annualized operating expenses by about $8.9 million and identified another roughly $4.6 million of annualized savings starting in the second quarter of 2026.

The mix shift matters here. Dragonfly has been leaning harder into OEM and commercial channels rather than just retail replacement batteries, which gives the growth story a more durable backbone if execution holds. Management also said the company is targeting positive adjusted EBITDA at a $70 million annual revenue run rate. That does not magically solve everything, because the business is still small and the stock is still volatile, but it does give the March update more substance than a generic “battery demand is strong” press release.

Dragonfly Energy Holdings Corp. (NASDAQ:DFLI) develops and manufactures lithium-ion batteries, energy storage systems, and related products, including its Battle Born Batteries brand, for RV, marine, trucking, off-grid, and industrial applications.
