Before ordering, I sent customer service the voltage and battery capacity of my 48V system. They confirmed by email that this was the appropriate model. The charger arrived quickly, and after more than ten charging cycles, it has performed reliably every time.

The original charger for my converted golf cart was inconsistent and occasionally stopped before the battery was full. This LiThink charger reaches 58.4V correctly and completes the charging cycle without random shutdowns. After several weeks, the battery SOC readings have also been more consistent.

I run a campground cart several times throughout the day. A slow overnight charger was not practical when the cart needed to be used again in the afternoon. The 20A output gives me a useful amount of charge during a shorter break.

Plug it into the battery, connect AC power, and watch the indicator lights. There are no unnecessary controls to adjust. It is powerful but still easy to use.

K

The battery protection had shut off after the cart was stored for an extended period. The charger was able to wake the battery and begin charging normally. I did not have to remove the battery or use another power source.

The output connector locks firmly and feels much better suited to a golf cart than exposed clamps. I still keep the charger under cover, but the sealed connection gives me more confidence when the garage floor or surrounding area is damp.

Our 48V utility cart is used around a large property for tools and supplies. The battery often comes back around 50% after a busy day. This 20A charger usually restores it in about three hours, so the cart is ready again by the evening.

The fan starts during charging and is clearly audible, but it keeps the housing from becoming excessively hot. I normally charge in the garage, so the noise does not bother me. The output has remained stable through every charging cycle.

B

The charger feels substantial and well built. The carrying handle is sturdy, the cables are thick, and the waterproof output connector fits securely. It arrived without any damage and was ready to use immediately.

I use this charger with a 48V 105Ah LiFePO4 battery in my golf cart. After a full day of driving, the battery was at approximately 38%. Charging back to full took a little over three hours. That is a major improvement over my previous lower-current charger.

The delivery process was poorly handled by the local courier.

I bought this charger together with a 48V lithium golf cart battery. The connection is straightforward, and the 20A output is suitable for charging between regular trips. The built-in fan runs during charging and helps move heat away from the unit. I normally charge in the garage, and the fan noise is noticeable but not excessive. Customer service confirmed the correct charging voltage before purchase, which gave me confidence that the charger and battery were properly matched.

This charger feels like a proper match for a 48V lithium golf cart setup. It charges consistently, and the fan cooling gives me more confidence during longer charging sessions. The design is straightforward, which I appreciate because I do not want a complicated charger for daily use.

Good charger for my 48V golf cart battery. The 20A output is practical for regular charging.

The charger works as expected, but the courier delivered it one day later than the tracking page showed. Not a big issue, but a bit inconvenient.

This charger feels suitable for a higher-voltage battery system. I use it with a 48V golf cart battery, and the 20A output is practical for regular charging. The fan runs during charging, which is expected for this power level.

Dropped this off my workbench onto concrete. Scratched the case but still works perfectly. Built tough.

Emailed support to ask if I should keep the charger plugged in during winter storage. They responded saying no, charge the battery to 60% and disconnect the charger. They explained the charger has a small standby draw and could slowly drain the battery over many months. Good to know. I follow their advice. Also said to store the charger in a dry place above freezing. Simple instructions.

I tracked 5 charge cycles on my 48V 105Ah golf cart battery. Average charge time from 30% to 100%: 2 hours 45 minutes. The first hour was full 20A, bringing the battery from 30% to 65%. The second hour tapered to 15A, 65% to 85%. The remaining 45 minutes tapered to 5A and then finished. The charger's fan runs during the first 2 hours, then shuts off when it switches to low current mode. The charger body is warm but not hot to the touch. I've left it plugged in overnight several times. The automatic shutoff works. The battery is always at 100% in the morning but not overcharged.

Left this at the golf course for everyone to use. Still there 3 months later. Works every time.

The cables on this charger are thick and flexible even in cold weather. The connectors are metal housing, not plastic that cracks. The charger body has rubber corner bumpers so it doesn't scratch what it sits on. The status LED is dual color, red for charging, green for done. Simple but well executed.

Asked about the warranty on the charger before buying. They responded clearly: 2 years, covers defects, process is to email photos and receipt. No runaround. Also told me to register the product on their website for faster service. Did it. Took 2 minutes. Good to know they stand behind their stuff.

I bought this to keep at the clubhouse so I don't have to carry my charger back and forth. It lives outside on a covered cart stall. Been rained on sideways, frozen, and baked in summer heat. Still working perfectly after 8 months. The aluminum housing feels industrial.

Used this to revive a 48V pack that had been sitting dead for 6 months (not a LiThink battery actually). The charger detected the low voltage and ramped up slowly instead of just dumping current. Saved me from buying a new battery. For the price, this is a very capable charger. Build quality feels commercial grade, not consumer toy grade.

Brought my 48V golf cart battery from dead to full overnight. The build quality feels premium and the fan is surprisingly quiet. Solid charger for the price, does exactly what it promises.

Title: Charges my 48V golf cart fast and reliably
Got this with my LiThink 48V 105Ah golf cart battery. It charges from 30% to full in about 3 hours—perfect for plugging in after a round and being ready for the next day. The build quality is impressive, heavy duty cables and a nice carry handle. The fan is audible but not annoying, and it only runs when needed. I've been using it for 3 months now, charges consistently every time. The connector fits snugly into the cart's charging port. No issues with overheating or cutting out early. If you're converting your cart to lithium, get the matching charger—it's tuned correctly for LiFePO4 and will extend your battery's life.

What cables are included with this 58.4V 20A charger?

Li Think

Thank you for your question and for your trust in Lithink. The charger includes an approximately 59.0 in / 1.5 m input cable, a 47.2 in / 1.2 m output cable, and a 19.7 in / 0.5 m extension cable. The output side also uses a waterproof connector to provide a more reliable connection in golf cart, garage, and outdoor charging applications.
