Reliable 48V golf cart chargers prioritize output current matching (5A–20A), IP67 waterproofing, and brand-specific compatibility. Top options include OHRIJA’s 15A/20A IP67 models for fast charging ($439–$675) and MAYOUNG’s budget 6A unit ($165). Always verify connector types (e.g., TXT/RXV/Yamaha) and input voltage (110V/220V) for seamless integration with lead-acid battery systems.
What Size Lithium Battery Do I Need for My Golf Cart?
How do I choose between 5A and 20A chargers?
Charger current (5A–20A) dictates charging speed and battery health. 5A chargers (e.g., OHRIJA 48V5A) suit occasional use, taking ~12hrs for 200Ah packs. 15A–20A models (OHRIJA IP67) recharge 200Ah batteries in 4–5hrs but require thicker 10AWG cables. Pro Tip: Higher amperage demands battery temperature sensors to prevent overheating during rapid charging. For example, a 48V20A charger delivers 960W—ideal for commercial fleets needing 3–4 daily cycles.
Why does waterproofing (IP67) matter?
IP67-rated chargers (OHRIJA/LZT) withstand dust immersion and 30-minute submersion, crucial for outdoor golf cart storage. Non-waterproof units (MAYOUNG 48V6A) risk internal corrosion from dew or rain splashes. These models use silicone-sealed casings and corrosion-resistant PCB coatings. Practically speaking, an IP67 charger lasts 3–5 years in humid coastal areas versus 1–2 years for basic units. Pro Tip: After washing your cart, always let charging ports dry completely before connecting.
| Feature | IP67 Chargers | Standard Chargers |
|---|---|---|
| Weather Resistance | Submersion-proof | Light rain only |
| Typical Lifespan | 5+ years | 2–3 years |
What connector types are essential?
Golf carts use brand-specific connectors: Yamaha 2-pin, Club Car TXT, or EZGO RXV. OHRIJA offers 8 connector variants, while WUYUAN’s 48V10A model supports G29 carts. Mismatched plugs can bend pins or cause arcing—always cross-reference your cart’s manual. For example, a TXT凹槽 connector has a keyed groove preventing reverse polarity. Pro Tip: Carry a connector adapter kit if your fleet mixes brands.

FAQs
No—lithium chargers lack voltage tapering, overcharging lead-acid cells. Use only chargers specifying “lead-acid” compatibility.
How to calculate charging time?
Divide battery capacity (Ah) by charger current (A). A 200Ah pack with 10A charger needs 20hrs (including 20% absorption phase loss).
