LiFePO4 price drop 2025 — is now the time to upgrade from AGM batteries?
This comes up constantly so let me give you the detailed breakdown based on real-world experience in Bloemfontein.
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: 103Ah LiFePO4 battery, 364W solar panel, Victron SmartSolar MPPT 100/30 controller, and a Redarc BCDC1225D for DC-DC charging from the alternator. Total investment: R28,000 all-in. It powers a National Luna 40L fridge 24/7 and runs LED lights, phone charging, and a 12V air compressor without any issues.
Common mistakes to avoid: Buying mismatched panels and controllers — always size your MPPT for at least 20% headroom above your panel wattage.
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 LiFePO4 price argument is now impossible to dispute. I paid R4880 for a 100Ah unit 26 months ago. At my daily usage pattern, I am nowhere near the 5783 cycle limit. The equivalent AGM cost I would have spent in two replacements already.
Freedom Won vs Hubble vs BSL — I have owned Freedom Won for 32 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.

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.
