Rich Solar 48V LiFePO4 Battery Charger | 20 Amp or 25 Amp

The Rich Solar 48V LiFePO4 Battery Charger Charges 48V Lithium Banks at 20A or 25A From a Sealed, IP67-Rated Aluminum Housing

The Rich Solar 48V LiFePO4 Battery Charger is an AC charger for 48V LiFePO4 batteries, offered as the 20A RS-BC48C20 or the 25A RS-BC48C25. Both run on 100 to 240V AC at 50/60 Hz and charge at 57.6V DC with a peak efficiency of 88 to 93%.

The die-cast aluminum housing is sealed and rated IP67, and an active cooling fan handles the heat of high-current charging. Both versions measure 11.3 x 7.8 x 3.5 inches and weigh 9.5 lb.

Rich Solar 48V LiFePO4 Battery Charger Features

20A or 25A at 57.6V

Pick the charging current that suits your battery bank. The RS-BC48C20 delivers up to 20A and the RS-BC48C25 up to 25A, both at 57.6V DC for 48V LiFePO4 batteries. Peak efficiency runs from 88 to 93%, so less of the power you pay for turns into heat.

Sealed IP67 Die-Cast Aluminum Housing

Rich Solar describes the housing as fully sealed against dust, water, impact and automotive-grade vibration, and says each unit is 100% full-load aging tested. Cooling fins and a guarded fan on the back carry heat away.

8-in-1 Protection

The charger guards against over-voltage, over-current, short circuit, reverse polarity, over-temperature and under-voltage. It also shuts off automatically and includes 0V battery activation.

Two-Color LED Status

Solid green means standby with no load, or a fully charged battery. Flashing green means the battery is charging. Flashing red means a fault or a protection event, such as low battery voltage, an output short circuit or reversed polarity.

Handle and Mounting Flanges

A carry handle sits on top, and slotted flanges on both sides let you fasten the charger in place.

Real-World Applications

48V battery banks. Charge a 48V LiFePO4 bank from 100 to 240V AC power.

Dusty or damp locations. The sealed IP67 housing suits garages, outbuildings and equipment areas where an open-frame charger could collect dust or moisture.

Practical Comparison

RS-BC48C20 Versus RS-BC48C25

The two versions share the same 57.6V output, 88 to 93% peak efficiency, protections, IP67 housing, 11.3 x 7.8 x 3.5 inch size and 9.5 lb weight. The only difference is maximum charging current, 20A or 25A.

Rich Solar 48V LiFePO4 Charger Versus a General-Purpose Charger

Many general-purpose chargers are designed around lead-acid batteries and open, vented cases. This charger is built for 48V LiFePO4 batteries at 57.6V and is sealed to IP67.

Buyer Guidance

Choose 20A or 25A

Check your battery's recommended charge current before you choose. The label on the charger notes that the charger must match the battery pack.

Connect in the Right Order

With the charger switched off, connect the DC output cable to the battery, positive to positive and negative to negative, and secure the Anderson connector. Turn the charger on; a flashing green LED means it's charging. Turn it off when charging is complete. Keep it ventilated while charging, away from flammable and explosive materials, and within its 14°F to 113°F (-10°C to 45°C) working temperature range.

This May Be A Good Fit If

• You have a 48V LiFePO4 battery or battery bank
• You want 20A or 25A of charging current from AC power
• Your charger will live in a dusty or damp space
• You want a fan-cooled, die-cast aluminum charger

Common Questions

Can It Handle Wet or Dusty Locations?

Rich Solar rates the housing IP67 and describes it as fully sealed against dust and water. Keep the charger ventilated while it runs.

Can It Charge a 12V or 24V Battery?

No. This charger is made for 48V LiFePO4 batteries and charges at 57.6V.

What Does a Flashing Red LED Mean?

The charger has detected a fault or entered protection. Check for low battery voltage, a short circuit at the output or reversed polarity.

What Certifications Does It Carry?

Rich Solar lists FCC, CE and RoHS compliance.
