Voltage vs. Battery level on Lectric Ebikes E-Bicycles


Understanding the battery life and depletion rate of an e-bike’s battery is crucial for riders who rely on their ebikes for long rides, daily commutes, or adventurous explorations. The chart we have meticulously crafted and displayed in our showcase represents a comprehensive interpretation of the power depletion for Lectric Ebikes’ 48-volt battery systems, encompassing both the dual and single battery configurations. Our analysis is not just based on a synthesis of various depletion charts available but is grounded in extensive empirical research conducted through rigorous testing processes on a variety of Lectric Ebike models from our own fleet.

To ensure our data reflected a broad spectrum of potential user experiences, we tested the ebikes under a diverse array of conditions. We included riders of differing weight classes and sizes to mimic the varied demographic of e-bike users. Our tests were conducted on terrains ranging from challenging hills to more forgiving flat landscapes, providing a robust understanding of how the battery performs under diverse stress levels.

Moreover, recognizing that ride style can significantly impact battery life, we enlisted riders with a wide range of cycling habits — from the pedal-heavy commuter to the throttle-reliant adventurer. We also tested across various accessory loads, equipping the bikes with everything from a full load-out pack to minimalistic setups, to measure the battery’s endurance against accessory-induced energy draw.

Our findings have led us to an important insight regarding the operational voltage of Lectric Ebikes. Despite the bike’s computer systems being designed to shut off at 40 volts to safeguard the electric components, we observed that the motor’s power is considerably diminished once the voltage drops below 42 volts. In fact, only the lightest riders with the least accessorized setups were able to perceive any substantial motor assistance under 42 volts, prompting us to equate 42 volts effectively to a ‘zero’ level in our charts for practical purposes.

Interestingly, our testing revealed that up until the voltage drops just below 49 volts, there’s hardly any noticeable decline in motor function, indicating that this voltage can be considered approximately the mid-point of the battery’s effective energy capacity. Following this threshold, a significant reduction in performance becomes evident, underscoring the importance of being mindful of battery levels, especially as they approach this critical voltage juncture.

We recognize the necessity of incorporating a margin of safety within our measurements to prevent riders from being unexpectedly stranded due to an overestimated battery life. Hence, while our numbers are approximations, they are carefully rounded up to include a safety buffer.

The chart is a testament to our dedication to providing reliable and practical accessories for Lectric Ebikes enthusiasts. It is essential to note that our innovative accessory chart is developed independently from Lectric. As Lectric does not publish its own battery depletion chart, we have taken the initiative to fill this void for the benefit of the ebike community. Our display case proudly features this chart, standing as a testament to our commitment to enhancing the riding experience for Lectric Ebike owners.


The data gathered from our extensive testing with Lectric Ebikes provides us with some very insightful findings regarding the relationship between the voltage displayed on the screens and the bike’s power output. It appears that a critical threshold exists around the 49-volt mark. Up to this particular voltage, riders generally do not experience a significant decline in the bike’s performance. They can continue to enjoy a robust pedal assist with little noticeable difference in the effort required to maintain their pace.

However, once the voltage dips below approximately 48 volts, things begin to change quite markedly. At this juncture, there is a palpable reduction in both the perceived effort and the actual power delivered to the rear wheel. This decrease in performance is not merely subjective; it translates into a tangible drop-off in assistance, making pedaling notably more challenging for the rider.

This phenomenon becomes even more pronounced as the voltage continues to decline. When the display shows 43 volts, several factors come into play that can influence whether the rider will receive any pedal assist at all. These factors include the rider’s weight, the number and type of accessories and modifications added to the bike, as well as the total cargo being transported. Under these conditions, it is primarily the lightest riders on bikes with minimal additional weight from accessories or cargo who can still benefit from the Pedal Assist System once the voltage falls below the 42-volt threshold.

During our tests, it was evident that these lighter riders managed to squeeze out the last bits of assistance from their ebikes, whereas riders with a heavier total load could not. Therefore, it is crucial for e-bike users, especially those riding Lectric Ebikes, to be aware of their battery voltage and plan their journeys accordingly. As they approach these critical voltage levels, they should be prepared for a more traditional cycling experience, with the electric assist becoming less reliable or ceasing altogether.
