A sodium-ion pack rather than lithium. Same wheeled format as the 628Ah unit, different chemistry — and the difference is worth understanding before choosing.

Where sodium-ion earns its place
Sodium cells hold less energy per kilogram than lithium, so a sodium pack is bigger and heavier for the same stored energy. In exchange they are far less troubled by cold, and the raw material is not lithium — which matters for supply and for cost stability.
The −40°C rating is not a selling point in Malaysia. It is relevant if you are specifying for export, for cold-chain equipment, or for an installation where a lithium pack's low-temperature charging limit would be a problem.
For an ordinary Malaysian installation, lithium is usually still the better fit. Ask us and we will say which we would put in.
Send us the voltage, capacity, discharge current and the space you have — or a photo of the battery you are replacing. We will come back with a specification and a price.
