The ShunTongDa 48V 10.4Ah is a replacement battery for the Lectric XP Step-Thru 1.0 and 2.0, designed to fit directly into the Lectric XP frame without requiring any modifications or specialized tools. It has 499.2Wh of capacity and a 5-pin discharge port. ShunTongDa has created multiple Lectric XP compatible batteries, and this one is targeted towards the Step-Thru models. If your original Lectric battery is losing capacity and you need a replacement, this is one to consider alongside other options on our comparison table.
The popularity of Lectric XP batteries has led to them becoming one of the most sought-after replacement products in the ebike space. The reason for this is the fact that the original batteries lose capacity over time after extended periods of usage. ShunTongDa has established themselves as a reliable source of aftermarket replacement batteries for ebikes, and the ShunTongDa 48V 10.4Ah is a prime example of this.
Specs and Build Quality
The ShunTongDa 48V 10.4Ah battery delivers 48V at 10.4Ah for a total of 499.2Wh of stored energy. The specifications indicate that the battery will deliver similar range to the original battery when used in conjunction with the Lectric XP's 500W nominal motor. The housing is constructed from ABS plastic and has a black top cover in the style of the Lectric battery. The intent behind the design is that it will appear and function like the original battery, but manufactured by a third party.
Physical specs
The physical dimensions of the battery are 18 x 3.93 x 1.69 inches (467 x 100 x 43mm), and you must ensure that they match those of your existing battery before purchasing. Since the ShunTongDa 48V 10.4Ah is a folding battery, it will sit either inside or beside the frame of the ebike, and small discrepancies in dimension may prohibit it from fitting properly in the frame. When viewing the product description, note that the title lists "L16.92 inch" which could refer to a different length version than the one you require, so be certain to select the correct length version of the battery for your particular model of ebike.
The ShunTongDa 48V 10.4Ah utilizes 18650 lithium-ion cells, which is the standard cell format utilized by ebike manufacturers in this category. The battery includes the battery, a charger, two keys for the integrated lock, and a user guide. The lock is a dual-purpose device that secures the battery to the ebike frame and simultaneously functions as the power switch. This means that you must leave the key turned on during each ride, and that you will need to know about this prior to taking your first ride to avoid confusion regarding why the ebike will not operate.
BMS and motor range
The built-in 30A BMS provides protection against overcharge, over-discharge, and shorts. As a result, the battery is capable of handling up to approximately 1440W of peak output at 48V and 30A, but ShunTongDa limits it to 800W for the motors that it supports. Given that the Lectric XP has a 500W nominal motor (that exceeds 500W under heavy load), the ShunTongDa 48V 10.4Ah will easily support the motor under normal operating conditions including hills and high-throttle usage.
According to ShunTongDa, the battery is capable of exceeding 1000 charge cycles and has a very low self-discharge rate. In practical terms, this equates to approximately three to four years of daily usage before the battery exhibits noticeable capacity degradation. The low self-discharge rate is a benefit in that it prevents the battery from draining itself when it is not in use. This is important if you do not ride your ebike daily, or if you only ride it during warmer months. The battery has a 1-year warranty according to the technical specifications provided by ShunTongDa, and they advertise 24/7 customer support and a satisfaction guarantee.
Form Factor and Compatibility
The ShunTongDa 48V 10.4Ah is specifically designed to serve as a replacement battery for the Lectric XP Step-Thru models (Step-Thru 1.0 and 2.0). The battery features a 5-pin connector, which matches the original Lectric battery connectors. This is intended to provide a plug-and-play experience, such that users can simply remove the original battery and insert the ShunTongDa 48V 10.4Ah without having to perform any rewiring or utilize adapter cables.
The battery features a folding form factor, which is designed to integrate with the ebike's fold mechanism. Therefore, the battery will only work on folding ebikes and will not work on traditional frame ebikes. Although the ABS plastic housing should be sufficiently durable to withstand normal riding conditions, it will not be as robust as an aluminum housing. Given that the battery will be housed in a protective area within the ebike frame, the ABS housing should be sufficient. The battery also features an integrated lock that secures the battery to the ebike frame and serves as the power switch. ShunTongDa makes other variants for different Lectric models, so make sure you are ordering the one that matches your specific bike.
Real-World Range Estimates
Based upon the 499.2Wh capacity of the ShunTongDa 48V 10.4Ah and the 500W nominal motor of the Lectric XP, you can estimate that the range will be comparable to that achieved by the original battery. Based upon moderate pedal assistance on flat to gently rolling terrain, this will typically translate to ranges of 20 to 35 miles per charge. Utilizing throttle-only or riding in hilly regions, you may anticipate ranges of 12 to 20 miles.
For commuting purposes, the range of the ShunTongDa 48V 10.4Ah should enable you to complete round-trip commutes of 10 to 15 miles without experiencing any range anxiety. For longer rides, you may want to limit your use of pedal assist and rely more heavily on your own pedaling. The charger that is included with the battery will recharge the battery from fully depleted to fully charged in approximately 5 to 7 hours, making overnight charging a convenient solution.
