Freedom Won vs Hubble Lithium vs BSL — South African LiFePO4 brands compared
This comes up constantly so let me give you the detailed breakdown based on real-world experience in Vaalwater.
The technology: The cost argument for LiFePO4 is now clear. A quality 100Ah LiFePO4 at R5,500 gives you 6,000 cycles at 90% depth of discharge. The equivalent AGM at R2,200 gives you 400 cycles at 50% DOD. Work out the cost per kWh over the lifespan — LiFePO4 wins by a factor of 4–6x. Freedom Won and Hubble Lithium are the SA brands with the best track record. BSL is newer but getting good reviews.
Pricing in SA (2025): R4,500–R7,000 per 100Ah depending on brand and supplier. Get at least 3 quotes — pricing varies significantly between installers and online suppliers.
My setup: 100Ah LiFePO4 battery, 374W solar panel, Victron SmartSolar MPPT 100/20 controller, and a Redarc BCDC1225D for DC-DC charging from the alternator. Total investment: R21,000 all-in. It powers a Engel MR040 fridge 24/7 and runs LED lights, phone charging, and a 12V air compressor without any issues.
Common mistakes to avoid: Undersized cables — voltage drop kills efficiency. Use the wire sizing calculators available online.
Happy to share my wiring diagram or go into more detail on any component. This stuff seems complicated but it really is not once you understand the basics.

The Eskom situation is interesting. My view: the 224 loadshedding-free days is excellent progress but I am not dismantling my solar system. Load reduction on overloaded feeders will continue regardless of Eskom's generation performance. And a home battery system has value beyond loadshedding — cheaper overnight electricity from time-of-use tariffs, backup during faults, and off-grid capability when you need it.

Good breakdown. On the DVCC settings — this is the single most important thing to get right with Victron and LiFePO4. Set your charge voltage limit to 14.2V maximum. I missed this initially and pushed my batteries to 14.6V repeatedly. They still work but I know I have shortened their lifespan.
Freedom Won vs Hubble vs BSL — I have owned Freedom Won for 33 months and it has been excellent. The BMS is conservative (some say too conservative) but it means you never accidentally overcharge. The 10-year warranty is genuine — they replaced a cell in my pack under warranty without questions.
