An open battery stacking system that is flexible, secure, and set up in only a few minutes.
Parallel up to six AES RACKMOUNT Battery Modules with a single AES RACKMOUNT Battery Combiner.

Advanced Integration - Faster Charging
Unlock the full potential of an AES RACKMOUNT LiFePO4 Solar Stationary battery by enabling the BMS to optimize and dynamically manage the charge configurations of the world’s best industrial chargers and mobile inverter-chargers. The LYNK PORT on each AES RACKMOUNT LiFePO4 allows for real-time closed-loop communication between multiple batteries and with a charger, or inverter-charger, using LYNK II to aggregate and communicate the State of Charge.


For installers wishing to install AES RACKMOUNT modules with their own wiring, this kit is available with both DC positive and negative connectors.
For installers not wishing to use the AES RACKMOUNT combiner, this cable kit includes both DC positive and negative wires with SurLok Plus connectors and ring terminals. These cables are 3 AWG and measure 2 meters in length.
