Intelligent 4-Stage Charging with 6-Layer Protection
Microprocessor-controlled charging follows the optimal LiFePO4 profile: Pre-charge → Constant Current (CC) → Constant Voltage (CV) → Automatic Cut-off. Built-in 6-layer safety protection includes over-temperature protection (auto-reduces current above safe limits), reverse polarity protection, short circuit protection, over-current protection, over-voltage protection, and no-load protection. LED indicator lights display charging status: red = charging, green = charging complete / standby.
Fast Charging Times – Up to 300Ah LiFePO4 Batteries
With 45A output, this charger dramatically reduces downtime. Approximate charging times from 0% to 100%: 100Ah battery ≈ 2.2 hours · 150Ah battery ≈ 3.3 hours · 200Ah battery ≈ 4.4 hours · 250Ah battery ≈ 5.5 hours · 300Ah battery ≈ 6.7 hours. Actual times vary with battery depth of discharge, temperature, and BMS charging limits.
IP65 Waterproof & Dustproof – Reliable in Any Environment
The fully sealed IP65-rated construction protects against water jets and dust ingress, making this charger suitable for marine, outdoor, and industrial environments. Whether mounted on a golf cart, boat, RV, or in a workshop, you can rely on consistent charging performance in rain, splashes, or dusty conditions.
Versatile Applications – Golf Carts, RVs, Marine & Off-Grid Solar
Designed for 24V (8S) LiFePO4 battery systems up to 300Ah, this charger is ideal for a wide range of applications: golf carts (Club Car, E-Z-GO, Yamaha 24V systems), RVs and campers, marine vessels (boats, yachts, trolling motors), off-grid solar systems (with battery storage), forklifts and industrial equipment, and electric utility vehicles.

Frequently Asked Questions
Is this charger compatible with all 24V LiFePO4 batteries?
This charger is designed for 24V (8S / 25.6V nominal) LiFePO4 batteries with a maximum charging voltage of 29.2V. It is compatible with LiFePO4 batteries up to 300Ah. Do not use it with lead-acid, AGM, GEL, or other lithium-ion chemistries (such as NMC or LCO). Always verify your battery's voltage and chemistry before charging.
How long does it take to charge a 100Ah LiFePO4 battery with this 45A charger?
With 45A output, a 100Ah LiFePO4 battery charges from 0% to approximately 100% in about 2.2 hours. For larger batteries: 150Ah ≈ 3.3 hours, 200Ah ≈ 4.4 hours, 250Ah ≈ 5.5 hours, and 300Ah ≈ 6.7 hours. Actual times may vary based on battery depth of discharge, temperature, and BMS charging limits.
Is this charger truly waterproof? Can I use it outdoors?
Yes. This charger features an IP65 waterproof and dustproof rating, meaning it is protected against water jets and dust ingress. It is suitable for outdoor use, marine environments, and industrial settings. However, do not submerge the charger in water or use it in areas where it may be fully immersed.
Does this charger work with both 110V and 220V outlets?
Yes. The charger features a universal 100–240V AC input with active PFC (Power Factor Correction). It works with standard outlets worldwide, including 110V (US) and 220V (EU/UK/AU) power systems. No voltage adapter or converter is required.
What safety protections does this charger include?
The charger includes 6-layer safety protection: over-temperature protection (automatically reduces current above safe limits), reverse polarity protection (internal circuit cuts off if battery is connected in reverse), short circuit protection, over-current protection, over-voltage protection, and no-load protection (no output when battery is not connected). LED indicator lights show charging status: red for charging, green for complete or standby.
Can I leave this charger connected after the battery is fully charged?
The charger automatically stops charging when the battery reaches full charge (indicated by the green LED). LiFePO4 batteries do not require float or trickle charging. For best battery longevity, it is recommended to disconnect the charger after charging is complete.
