The StamiNa+ range

Sodium-Ion Batteries Uganda: the StamiNa+ Range

Sodium-ion batteries Uganda can rely on, from a Ugandan company owned and led from Wakiso District and backed by AceOn Group UK's 30+ years of British battery expertise. StamiNa+ is our sodium-ion range: cobalt-free, lithium-free and nickel-free chemistry, rated for discharge from −40°C to +70°C, with a UK-developed battery management system in every pack.

Sustainable. Reliable. Staying Power.

What sodium-ion is, and why the chemistry matters

A sodium-ion cell moves sodium ions between its electrodes to store and release energy, in place of the lithium ions used by the batteries most people are familiar with. Sodium is one of the most abundant elements on earth. That single substitution changes the economics and the safety profile of the finished pack, and it removes three of the most contested materials in the battery supply chain at once: there is no lithium, no cobalt and no nickel anywhere in the cell.

Every StamiNa+ pack is built on the NaCR32140-MP10 cell in the 32140 cylindrical format, assembled to a 12 V nominal configuration with passive cell balancing. A smart battery management system sits on top, protecting against over-charge, over-discharge, over-current and short-circuit conditions. That management system is AceOn Group UK engineering, and it is rated to operate from −40°C to +85°C — a wider window than the cells themselves need, so the protection never becomes the limiting factor in the heat.

The packs carry CE, UN38.3 and WEEE marks on the product label. UN38.3 is the transport-safety qualification for shipping cells and batteries, which matters for anyone moving stock across borders in the region.

Sodium-Ion Batteries Uganda Can Rely On

Four things make this chemistry a good fit for conditions across Uganda and East Africa — high ambient temperatures, long distances, intermittent grid power and supply chains that punish anything exotic.

Enhanced safety

Stable chemistry with no thermal-runaway risk. Abuse testing returned no fire and no explosion. Safe to ship, store and use anywhere.

Wide temperature range

Operates from −40°C to +70°C, with the battery management system itself rated to +85°C. Built for real African heat and remote conditions.

Sustainable materials

Made from abundant materials. No lithium, no cobalt, no nickel. A cleaner supply chain and a lower cost base.

Long service life

Thousands of cycles of dependable staying power. The figure differs by product and is quoted per product below — never as one number for the range.

Cycle life is quoted per product, never as a single figure for the range. The soft packs are rated ≥5,000 cycles at ≥70% capacity; the PES Lite 120Wh is rated ≥3,000 cycles at 80% depth of discharge; the NA12100 12V 100Ah is rated ≥2,000 cycles at ≥70% capacity. They are measured differently and are not interchangeable.

How sodium-ion compares with what most sites run today

Most homes, clinics, schools and small businesses in the region are running one of three things today: a lead-acid bank, a lithium-ion pack, or a diesel generator. Each has a reason it got chosen, and the honest comparison is the one that puts the criteria that actually decide a purchase side by side — how the chemistry behaves when it fails, how it copes with heat, how long it lasts, and how exposed its materials are to price shocks.

Selection criteria: StamiNa+ sodium-ion against the common alternatives
Criterion	StamiNa+ sodium-ion	Lead-acid	Lithium-ion (LFP)	Diesel generator
Safety	No thermal-runaway risk. Abuse tested: no fire, no explosion.	No thermal runaway, but sulphuric acid is corrosive and charging vents hydrogen — requires ventilation.	Thermal runaway is possible; requires a BMS; classed as dangerous goods for shipping under UN38.3.	Flammable fuel stored on site; exhaust contains carbon monoxide and particulates; must be run ventilated.
Temperature	Discharge −40°C to +70°C. Charge −20°C to +60°C (soft packs). BMS rated −40°C to +85°C.	Roughly −20°C to +50°C, but loses about half its capacity at −20°C, and service life halves for every ~10°C above 25°C.	Charging below 0°C causes permanent lithium plating — typical charge window 0°C to +45°C.	Wide ambient range, but difficult to cold-start below ~0°C and derates in high heat.
Cycle life	Soft packs ≥5,000 cycles at ≥70% capacity. PES Lite ≥3,000 cycles at 80% DoD.	~300–500 cycles at 50% depth of discharge.	~2,000–6,000 cycles at 80% depth of discharge.	Not cycle-rated — measured in running hours, with servicing every 200–500 hours.
Material supply	Abundant materials. No lithium, cobalt or nickel.	Lead is abundant and highly recyclable, but toxic and subject to regulated handling and disposal.	Lithium and nickel come from concentrated supply chains with volatile pricing.	Requires continuous fuel supply — price volatility and transport cost to remote sites.

The lead-acid, lithium-ion and diesel figures are typical for each technology category, not claims about any particular product or manufacturer. Real-world figures vary by design, duty cycle and installation. The sodium-ion column is different in kind: those are AceOn StamiNa+ product specifications, taken from our datasheets.
