This is a dedicated 48V lithium charger built for outdoor and harsh-environment installations. It takes 220V AC input and outputs 57.6V DC at up to 50A, and its IP65 rating means it is sealed against dust and low-pressure water jets — a fit for pump houses, outdoor battery cabinets, and marine dock boxes where a standard indoor charger would not survive.

Why This Charger, and What It's Not For
A charger is not an interchangeable commodity part. Voltage, output current, and connector compatibility all have to match your battery bank's chemistry and BMS charge limits, or you risk undercharging, tripping a BMS lockout, or damaging cells. This is a 48V-nominal lithium charger, sized for banks that call for a 57.6V DC charge voltage — the standard absorption point for 48V LiFePO4 packs (16S configuration). It is not a universal charger, and it is explicitly excluded from use with BigBattery BDGR batteries, per the manufacturer.
Charger Characteristics
- Chemistry Target: Lithium (LiFePO4), 48V nominal bank
- AC Input: 220V AC
- DC Output: 57.6V DC
- Max Output Current: 50A
- Enclosure Rating: IP65 (weatherproof — dust-tight, protected against low-pressure water jets)
Wiring & Configuration Limits
This charger is designed for a single 48V lithium battery bank at its rated 57.6V DC output. It is not a multi-stage lead-acid charger and is not intended for series/parallel-stacked voltage configurations beyond the 48V nominal target it is built for — do not attempt to use it on a 24V, 36V, or 96V bank. It is explicitly not to be used with BigBattery BDGR batteries.
Pro-Installer Tip
Charging lithium at the wrong voltage set-point is the most common cause of premature BMS lockout on 48V banks. A charger outputting 57.6V DC is calibrated for a 16S LiFePO4 pack — if your bank's BMS charge-voltage limit does not match this figure, the BMS may cut off charging mid-cycle or, over repeated cycles, allow cell imbalance to creep in undetected. Before wiring this charger into a bank, confirm the pack's rated absorption voltage against the charger's 57.6V DC output, and verify with a shunt-based battery monitor that the bank reaches full charge without early BMS disconnect. For lithium chemistry, plan cycles around an 80-100% depth of discharge window rather than the 50% DoD ceiling used for lead-acid, and let the BMS — not manual guesswork — govern the top-end cutoff.
Key Points
- IP65 enclosure allows outdoor or exposed-location mounting where indoor-rated chargers cannot be installed.
- 50A max output supports faster bulk charging on larger 48V lithium banks versus lower-amperage chargers.
- Fixed 57.6V DC output matches standard 48V (16S) LiFePO4 absorption voltage.

FAQ
Can I use this charger with BigBattery BDGR batteries?
No. The manufacturer specifically excludes BDGR batteries from use with this charger.
What AC input and DC output does this charger use?
It takes 220V AC input and outputs 57.6V DC at up to 50A.
Is this charger safe to install outdoors?
It carries an IP65 rating, meaning it is sealed against dust and protected from low-pressure water jets, making it suitable for exposed or outdoor installation locations.
Will this charger work on a 24V or 12V lithium bank?
No. It is built for 48V-nominal lithium banks with a 57.6V DC charge voltage target and is not suited to other bank voltages.
