The Freedom Won Auxiliary FW12 Range offers high-performance 12.8 V lithium-iron-phosphate (LiFePO₄) batteries in multiple capacity options – 1.28 kWh (FW 12-100), 2.56 kWh (FW 12-200, implied) and smaller capacities (e.g., FW 12-20 at 256 Wh, FW 12-7.5 at 96 Wh) – designed for auxiliary and off-grid storage use. The range is built for strong cycle life (over 2,000 cycles at full depth of discharge) and rugged environmental tolerance (IP56, broad temperature range) suitable for a wide array of applications.
Features & Benefits
- High cycle life: The >2,000 cycle rating at full depth-of-discharge means long-term reliability and lower replacement frequency, reducing total cost of ownership.
- High efficiency: Very high charge/discharge efficiency (up to ~99%) ensures that stored energy is utilised effectively—especially important where solar input is limited.
- Wide temperature tolerance: With discharge capability down to –20 °C and up to 60 °C, these batteries handle diverse climatic conditions, which is relevant for Tanzania’s climate variation between regions.
- IP56 protection and rugged construction: Good ingress protection against dust and water ingress enhances suitability for installations in remote or harsh environments.
- Compact 12.8 V format: Compatible with many existing 12 V inverter/charger systems, making retrofits easier.
- Advanced BMS (Battery Management System): Protection functions include over-charge, over-discharge, over-current, short-circuit, temperature protection and cell balancing. E.g., FW12-100 lists protection functions.
- Low self-discharge: Less than 3% per month means batteries hold charge well during idle periods—useful for backup systems or seasonal usage.
- Scalable capacity options: From small 96 Wh up to 1.28 kWh and beyond in the same family means flexibility for different applications and budgets.
Use Cases
For the Tanzania market, some practical use cases include:
- Residential backup power: Homes subject to load-shedding or grid instability can use these batteries paired with solar panels or an inverter system to keep critical appliances (lights, fridge, fans, communication devices) running.
- Small business / kiosk backup: Shops, kiosks, or small offices can use a FW12-100 or multiple units to maintain operations during power disruptions.
- Solar off-grid / hybrid systems: In rural or semi-rural locations with unreliable grid access, these batteries enable storing solar during the day for evening/night usage.
- Telecom and remote equipment backup: Equipment shelters, telecom base stations, or remote monitoring systems can leverage the smaller capacity models (e.g., FW12-20, FW12-7.5) as auxiliary batteries.
- Mobile or recreational use: Vehicles, boats, caravans, remote cabins in Tanzania’s tourism/light-utility sectors can use the compact units for auxiliary power.
- Emergency lighting / standby systems: Schools, clinics, or community centres may install these for essential loads in case of outage, providing a durable and long-life backup solution.
Value Propositions & Local Market Positioning
- Reliability in challenging environments: With Tanzanian conditions of heat, dust, and occasional rough access, a rugged LiFePO₄ battery with IP56 and wide temperature tolerance stands out versus cheap lead-acid batteries.
- Lower maintenance & longer lifespan: Compared to lead-acid alternatives which require frequent maintenance, watering, replacement and have lower cycle life, the Freedom Won LiFePO₄ range offers lower ongoing cost and hassle.
- Better performance for solar-based systems: Efficiency and deep-discharge capability mean more of the solar-generated energy is stored and used—important where solar resource is the key input.
- Flexible capacity options for different budgets: Whether a homeowner wants a small backup for lights (FW 12-7.5) or a larger system (FW 12-100), the range allows matching capacity to need and budget.
- Compatibility with existing 12 V infrastructure: Many systems in Tanzania use 12 V inverters and solar charge controllers; the 12.8 V nominal voltage fits seamlessly.
- Economic benefit in load-shedding or grid-unstable areas: By reducing downtime and protecting business or household continuity, these batteries offer value beyond purely cost—they are an investment in resilience.
- Scalability and upgrade path: Users can start with a smaller capacity unit and expand later or choose a larger one upfront, aligning with budgets and future growth.
- Safety and environmental credentials: LiFePO₄ chemistry is inherently safer than some lithium alternatives (less thermal runaway risk) and has better lifecycle aspects than lead-acid; this may resonate in Tanzanian markets with increasing focus on sustainable energy solutions.
Local Market Insights & Positioning Tips for Tanzania
- Highlight backup benefit for unreliable grids: Emphasising protection against power cuts and load-shedding will resonate strongly in the Tanzanian context.
- Bundle with solar-inverter solutions: Marketing the battery together with solar panels or a local inverter/charger partner will help customers see the full system value.
- Focus on total cost of ownership: Compare lifecycle of conventional lead-acid vs LiFePO₄ in terms of cycle life, maintenance, replacement frequency and efficiency losses.
- Emphasise warranty and support: While local service may be limited, ensure customers know about the support infrastructure (distributors, installers) and warranty coverage.
- Educate on safe install and proper sizing: Because batteries require correct charge/discharge control (voltage settings, cable sizing, ventilation) installing in Tanzania with local installers may need training. The manual supports this.
- Offer capacity matching for customers: Start with smaller capacity models for basic loads (lighting, communications) and offer upgrade path for larger loads (fridge, fans, appliances).
- Promote after-sales and lifespan advantage: If local electricity costs and solar panel costs are high, emphasising long lifespan (2,000+ cycles, many years of service) will strengthen the value proposition.
- Consider import / local distribution logistics: Consider shipping, customs, local taxes, warranty servicing in Tanzania; emphasise local stock or fast shipping to reduce downtime.
- Tailor to commercial/industrial backup too: For small businesses, telecom towers, remote lodges, promoting the FW12 100 may make sense as a compact yet high-capacity backup battery.
- Price psychology: While Li-ion systems often cost more upfront than lead-acid, presenting the cost per usable kWh (after losses, maintenance, replacement) usually shows value—this is important for decision-makers in Tanzania.
