HiTHIUM’s ∞Power 6.9 MWh BESS is housed in a 20-foot container
It is equipped with 1,300 Ah LFP battery cells
The company expects its commercial availability starting in 2027
Battery energy storage system (BESS) provider HiTHIUM unveiled its latest product, ∞Power 6.9 MWh, focused on AI data center applications, at SNEC 2026.
The BESS is housed in a 20-foot container and equipped with 1,300 Ah lithium-iron-phosphate (LFP) battery cells. According to the company, the BESS has a storage capacity of 6.9 MWh for 8 hours. Compared to a 4-hour standard storage system, the BESS is built with LDES-dedicated cells and adopts an operational thermal control mechanism. The company claimed that the cooling mechanism is more advanced than traditional peers, though they didn’t provide any further details. The batteries have a service life of more than 20 years. The company claims it uses ultra-thick electrode technology that reduces the cost of power components by 50% compared with traditional peers. Its 4 times higher capacity compared to conventional 330 Ah or 340 Ah LFP cells reduces system components by more than 30%.
The storage helps achieve an all-day green power supply by discharging the energy stored during the day. The company claims that its integrated prefabricated design boosts system deployment efficiency by up to 18% and reduces footprint by 23% compared to conventional counterparts.
The company has started taking orders for this BESS, with expected mass production starting in 2027.
