Naali 1.3 kWh (ACB13A, 12.8 V) 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 three capacity tiers — 1.3 kWh, 2.6 kWh and 5.4 kWh — each offered with a choice of voltage wiring on the same physical unit. List prices below are ex. VAT (+ ALV).
Available in 12.8 V (105 Ah) only. Dimensions 23.2 × 17.5 × 17.5 cm. LiFePO4 (LFP) battery with active heating, CAN bus (NMEA2000) and Bluetooth connectivity — see shared platform specifications below.
Available wired as 12.8 V (105 Ah) or 25.6 V (210 Ah) — same physical unit, same weight, dimensions and price either way. Dimensions 27.6 × 19.5 × 24.8 cm. LiFePO4 with active heating, CAN bus (NMEA2000) and Bluetooth connectivity.
Available wired as 25.6 V (105 Ah) or 51.2 V (105 Ah) — not available in 12 V. 290 × 255 × 370 mm, 38 kg. LiFePO4 with active cell heating — charges down to −40 °C — plus CAN bus (NMEA2000) and Bluetooth connectivity.

During testing for a demanding Arctic rescue system, the Naali 1.3 kWh (12.8 V) was the only battery able to maintain the required 36 °C heat output for over four hours. A follow-up lab run exceeded 24 hours with no sign of performance drop before the test was called.
