Arctic-ready energy for mobile, remote and engineered systems.
Naali combines lithium iron phosphate (LiFePO4/LFP) cells with a smart battery management system, active heating and CAN bus/Bluetooth connectivity — built for the demands of the North and engineered energy projects.

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 and 48 V classes, with a 24 V class in development. Specifications below are as documented for each model — nothing is inferred between variants.
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.
A 24 V class Naali battery is in development. Confirmed specifications have not yet been published — contact us to discuss your application and be notified when technical documentation is available.
LiFePO4 (LFP) battery with Bluetooth app, RJ45 CAN bus and battery-link connections. Continuous discharge 100 A, pulse discharge 200 A for 30 seconds. Up to 16 units can be paralleled with unique addresses, equal-length cables and a suitable common busbar.
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.

"The Akkutalo Naali A13 was the only battery to meet our requirement of maintaining 36°C for four hours. In a laboratory test it exceeded 24 hours without signs of diminishing before the test was terminated."
This is a customer-reported result shared for context. It is not an independent product certification or laboratory accreditation.
Naali batteries support a wide range of professional and engineered use cases — grouped here by the problem they solve.
Safety-critical, infrastructure and transport applications: suitability subject to application review.
Akkutalo can discuss configuration and integration options with your project team. These are engineering options subject to project review — not standard features on every product.
Every project is different. Share your load profile, environment and communications requirements, and we'll advise on the right Naali configuration and any integration work needed.
