Free shipping, tax (vary by region) and discount codes calculated at checkout

  • Designed for LiFePO4 Batteries: Ampere Time 29.2V 20A LiFePO4 battery charger is special for charging 24V lithium iron phosphate (LiFePO4) battery and battery bank, which enables to fully charge LiFePO4 battery to 100% capacity compared with a non-LiFePO4 battery charger to 90% capacity, it maximizes and optimizes the lithium battery performance, and extends the battery lifetime to a large extent.
  • 100% Safety & Reliability: Low failure rate and good heat dissipation capacity, built-in 4 safety protections during charging: Reverse polarity protection, output short circuit protection, output overvoltage protection, battery isolation protection. Set you free from worrying about the uncertain safety factors in the charging process.
  • 0V Charging Mode for Dead Battery: Switching power supply and microcontroller-controlled charging technology makes the charger have an exclusive pre-charge mode, which can reset the battery after BMS 0V protection trigger, repair long unused or deeply sleeping battery, and extend its life.
  • High Charging Efficiency: Inclusive rated input voltage from 100V-240Vac, 45Hz to 65Hz, Ampere Time 29.2V 20A LiFePO4 battery charger maintain stable voltage accuracy at ±0.2V (approx.29V to 29.4V) and affords output constant current at 19A to 21A, it enables more than 90% high charging efficiency for lithium (LiFePO4) iron phosphate battery charging.
  • Worry-free guarantee & faster delivery time: Ampere Time provides a 2-Year warranty for all LiFePO4 battery chargers with 24/7 customer service. Located on US local warehouses, enables faster delivery time in the American region.
