Naali 12 V (ACB13A) shown
Four capabilities behind every Naali battery — always subject to the connectivity and options supported by the specific model you choose.
Naali is the Finnish word for the arctic fox — an animal built to thrive in the same cold, exposed conditions our batteries are engineered for. Small, resilient and efficient, it stores and conserves energy through the harshest Nordic winters.
All performance and safety statements rest on the documented specs and linked datasheets.
Naali is available today in 12 V, 24 V, and 48 V classes. Specifications below are as documented for each model.
LiFePO4 (LFP) battery with active heating, CAN bus and Bluetooth connectivity. Continuous discharge 100 A, pulse discharge 200 A for 30 seconds. Discharge range −20 to +55 °C.
The 24 V class Naali battery is available. Full technical specifications are being finalized and will be published shortly — contact us to discuss your application in the meantime.
LiFePO4 48 V class battery with active cell heating — charges down to −40 °C. CAN bus and Bluetooth connectivity for full system integration.
Values below are drawn directly from the current documented source for each model. The 24 V class has no published specification yet, so none is shown.
