REPT Battero launches 392 Ah cell, 6.26 MWh storage system

Hong Kong-listed REPT Battero launched a new battery cell at the 13th Energy Storage International Conference and Expo (ESIE 2025) in Beijing last week.

REPT Battero said its new 392Ah battery cell, which is part of its brand of Wending series cells, has an energy density of up to 415 Wh/L. Billed as an “all-rounder” by the company, the new cell has a longer cycle life of 12,000 times and a high energy efficiency of 95%, while having almost the same size of the previous 300+ series. The company says the improving maturity of its chemical system delivers a higher capacity cell in the same sizing.

The maximum thermal runaway temperature of the 392 Ah cell is similar to that of the 314 Ah cell which the company says were tested at “home and abroad” in unspecificed safety tests.

REPT Battero has regularly announced new cells from its production sites, including a 564 Ah battery cell at the RE+ 2024 conference in the USA last year, designed for storage of more than four-years. Comparatively, the 392 Ah cell offers longer cycle life and a smaller cell design.

Powtrix 3.0

The company also unveiled its Powtrix 3.0, its latest energy storage system incorporating the 392 Ah battery cells, delivering a 6.26 MWh BESS packed in a 20-foot standard container. Figures provided by the company suggest that new Powtrix, when compared to its last 5 MWh system, delivers a 20% increase in energy density within the energy storage battery cabin. This saves on land and a company quoted figure of 18% savings for “on-site working hours.” The new design also features active balancing to reduce downtime and increase utilization.

The company also announced this year that it is building a factory in Indonesia for lithium-ion batteries, modules, and packs, catering to both electric vehicles and energy storage systems.
