Lithium-Ion Phosphate (LiFePO4) Battery Chargers
Mascot lithium iron phosphate (LiFePO4) battery chargers engineered for the safer, longer-life lithium chemistry increasingly specified in medical, marine, mobility, robotics and professional portable equipment. The range Single-cell through multi-cell packs at a nominal 3.2 V/cell, with charge currents from several hundred milliamps up to several amps and float voltages tuned to the 3.6 V/cell endpoint that LiFePO4 cells require. Charge profile Constant-current / constant-voltage (CC/CV) dedicated to LiFePO4 — bulk charging at rated current until the per-cell float voltage is reached, then voltage-limited absorption until termination current is met. End-of-charge is signalled by status LEDs. Built-in protection • Reverse polarity • Output short-circuit • Over-temperature • Incorrect pack voltage Why LiFePO4 Compared with standard Li-Ion, LiFePO4 chargers deliver longer cycle life, improved thermal stability and a wider safe operating window — well suited to deep-cycle applications and equipment charged and discharged daily. Compliance & fit CE and UKCA marked. Supplied with interchangeable mains plug heads and a wide choice of DC output connectors to match standard pack assemblies.

LiFePO4 (lithium iron phosphate) battery chargers
A LiFePO4 (lithium iron phosphate) battery charger delivers the 3.6V-per-cell CC/CV profile that lithium iron phosphate cells require — a lower and more forgiving end-of-charge voltage than standard Li-Ion, matched to LiFePO4's excellent cycle life and thermal stability.
Pulsar Developments supplies UK-stocked Mascot LiFePO4 chargers for 12V, 24V, 36V and 48V packs, covering leisure, marine, off-grid, robotics and industrial standby applications where LiFePO4's 2,000+ cycle life and safer chemistry make it the preferred replacement for lead acid.
What to look for
- Pack voltage. LiFePO4 nominal is 3.2V per cell; fully-charged is 3.6V. A '12V' LiFePO4 pack is actually 4 × 3.2V = 12.8V nominal, 14.4V fully-charged — quite different from a 12V lead acid charger.
- BMS compatibility. All professional LiFePO4 packs include a BMS. Our chargers deliver the well-behaved CC/CV profile the BMS expects, without over-voltage triggers.
- Charge current. LiFePO4 tolerates 0.5C–1C charging comfortably. Higher rates are possible on cells rated for it — check the pack spec.
- Replacement for lead acid. Same physical footprint, 3–4× the cycle life, half the weight — but you must swap the charger. A lead acid charger will over-charge LiFePO4.
Frequently asked questions
- Can I use a lead acid charger on a LiFePO4 battery?
- No. A lead acid charger's absorption voltage (typically 14.4–14.8V for a 12V pack) plus indefinite float will over-charge a LiFePO4 pack and trigger BMS shutdown or cell damage. Always use a dedicated LiFePO4 charger.
- What's the correct end-of-charge voltage for LiFePO4?
- 3.6V per cell — so 14.4V for a 4-cell (12V) pack, 28.8V for an 8-cell (24V) pack, 57.6V for a 16-cell (48V) pack. Our Mascot chargers are preset to the correct value per model.
- Why choose LiFePO4 over standard lithium-ion?
- LiFePO4 offers 3–5× the cycle life (2,000+ vs 500–1,000), inherently safer thermal chemistry (no thermal runaway), and stable performance over a wider temperature range. The trade-off is slightly lower energy density.
- How long does a LiFePO4 pack take to charge?
- At the standard 0.5C rate, a full charge from empty takes around 2 hours. A 1C fast charge completes in around 1 hour on cells rated for it.
