Performance

Power Output and Runtime

When it comes to real-world usage, performance is where the LOSSIGY 48V battery shines. The 100Ah capacity paired with a 51.2V nominal voltage provides a substantial 10.24 kWh energy bank, making it suitable for full-day activities in golf carts or off-grid RV setups. Users report mowing large plots—up to 1.68 acres—on a single charge, which translates to increased efficiency and reduced operational downtime.

The internal Battery Management System (BMS) helps balance the cells and protect against overcharging, over-discharging, overheating, and short circuits. With a continuous discharge current of 200A, it handles heavy workloads easily. That, combined with the peak discharge current of 1000A, makes this battery ideal for golf carts requiring a burst of power on hilly terrain or under heavy load.

Charging

The included 18A lithium charger charges the unit efficiently and safely. It also maintains the lithium chemistry’s health by adhering to the appropriate voltage profile. A full recharge can typically be achieved within 5 to 6 hours, depending on usage.

Weight Efficiency

Compared to traditional lead-acid batteries—especially when used in series to build 48V systems—the LOSSIGY battery saves a significant amount of weight. Users have reported a reduction of approximately 400 pounds in total vehicle weight, which improves both energy efficiency and vehicle maneuverability.

Customer Feedback

Customer reviews of the LOSSIGY 48V Lithium Battery have been largely positive across various platforms. Here are some highlights based on verified user experiences:

Installation and Setup

Users frequently praise the battery’s plug-and-play nature. It is considerably more straightforward to install compared to assembling four 12V lead-acid batteries. The unit’s single-package design means there are fewer cables and fewer opportunities for errors or corrosion at terminals. One customer noted that Bluetooth setup took only 30 seconds, which speaks to its user-friendly nature.

Reliability in Use

For users running extended operations like fishing trips, RV road trips, or mowing large lawns, the battery has proven reliable for full-day use without requiring a midday recharge. This greatly enhances convenience and productivity.

Bluetooth App and LCD Monitor

The integrated Bluetooth connectivity and LCD display are lauded for enabling real-time monitoring. Voltage, charge level, temperature, and usage metrics can be viewed on the app, giving users transparency and control. This is especially useful for those managing solar systems or needing accurate state-of-charge data during mobile applications.

Durability and Build

Users appreciate that LOSSIGY uses automotive-grade A cells, resulting in longer life expectancy and better structural integrity. No swelling, overheating, or faulty readings have been widely reported, reinforcing confidence in the build quality.
