CUBE battery system
Air-cooled LFP Battery System
CUBE provides a modular battery design with superior energy density. Any scale of power storage is available by freely configuring modular units in strings of up to 1,000 VDC. They include an integrated Battery Management System (BMS), gas exhaust and pre-charge functionality. A battery cluster with up to 16 battery strings and 1 control cabinet provides a capacity of 2.2 MWh. The CUBE system is scalable from a few kWh to several MWh and allows for optimal use of battery room space.Read moreAQUBE battery system
Water-cooled 2C LFP battery system
AQUBE combines the compact design of the CUBE system with water cooling from COBRA. It uses safe LFP cells with continuous 2C charge/discharge. Compared to NMC, LFP is safer and eco-friendly—no fire risk in thermal runaway. AQUBE suits ferries, OSVs and yachts with short turnaround cycles or high peaks. Modular units scale up to 1,000 VDC. Includes BMS, custom racking and switch unit.Read more
