Lithium battery prices that make sense, from a supplier that keeps them in stock.
X Solar stocks 12V, 24V and 48V LiFePO4 lithium batteries for solar, inverter backup and off-grid use — with built-in BMS protection and nationwide delivery.
Why LiFePO4 over lead-acid or gel
Lithium iron phosphate costs more upfront than a lead-acid or gel battery of the same size — but it lasts long enough that the cost per cycle usually ends up lower.
Cycle life
Rated for 6,000+ cycles at 80% depth of discharge, versus roughly 500–1,200 for lead-acid.
Safety
Thermally stable and non-flammable compared to other lithium chemistries, with built-in BMS cut-offs.
Weight
Roughly half the weight of an equivalent lead-acid battery — easier to install, mount or move.
Maintenance-free
No topping up electrolyte, no equalisation charging — the BMS handles cell balancing automatically.

Lithium battery questions, answered
A 12V 100Ah LiFePO4 lithium battery typically costs between R2,500 and R3,800 in South Africa, while a 48V unit sized for whole-home backup runs from around R10,500 to R21,000, depending on capacity and BMS quality.
The main drawback is upfront cost — LiFePO4 batteries cost more per kWh than lead-acid or gel at purchase, though their far longer cycle life usually brings the cost-per-cycle down over time. Performance can also dip slightly in very cold temperatures, though quality units include internal protection for this.
A quality LiFePO4 battery is typically rated for 6,000 or more charge cycles at 80% depth of discharge, which works out to roughly 10–15 years of daily use, well beyond the 3–5 years typical of lead-acid or gel batteries.
South Africa has some lithium mineral deposits and exploration projects underway, but most LiFePO4 battery packs sold locally, including ours, use cells manufactured internationally and assembled or packed for the South African market.
Yes — most smartphones use lithium-ion cells, which is a different lithium chemistry to the LiFePO4 (lithium iron phosphate) batteries used for solar and backup power. LiFePO4 trades some energy density for much greater safety and cycle life.
