A dying OEM pack should not write off a whole bike, and this ShunTongDa 48V 10.4Ah battery exists precisely for that moment. It is a 499Wh drop-in for the Lectric XP Step-Thru 1.0 and 2.0 with the right 5-pin connector and folding-frame fit. The catch: it is new to the market with zero reviews of its own, so you are buying the brand's track record, not this pack's.
Specifications and Value
It claims to be at 499.2Wh, based off the 48V and 10.4Ah cells used in the battery. These values are standard energy densities for the Lectric XP Step-Thru models (the 1.0 and 2.0). With a 5-pin discharge connector, you get a true plug and play experience. There is no need to solder any connections or do custom wiring which greatly reduces the chance of creating a short circuit when installing and potentially burning out your controller. The battery functions as a large capacity fuel tank ensuring that your motor always has the necessary energy to function without overheating.
The 30A BMS enables the battery to supply up to 1440W of peak power although the manufacturer says it supports motors up to 800W. Your xp uses a 500W nominal motor so this battery provides ample margin to prevent voltage drop due to climbing a hill. The battery contains 18650 lithium-ion cells that claim to provide over 1000 charge cycles. For example, if you ride every day for a year you may notice that your battery has lost enough capacity that you'll have to buy another replacement unit. The internal protection prevents overcharging, over-discharging and short circuits protecting the cells from damage during extended periods of use.
Folding Frame Design and Fit
This battery is designed specifically for folding ebikes using a battery tray and is made with an ABS plastic housing featuring a black upper plate that simulates the appearance of the original OEM item. As such it appears as if it was factory installed and not some generic aftermarket replacement item.
In addition, the design includes integration into the bike's folding mechanism. One unusual characteristic mentioned in the specifications is that the integrated locking system serves as both the lock and the power switch. To ensure continuous operation of the bike while you're riding the key must remain in the "on" position. Failure to do so could cause your power to shut down and leave you stuck on the side of the road. The design ensures that the battery remains securely attached while you fold your bike for transportation in smaller vehicles.
Real-World Range and Power
Amazon lists this battery as providing between 20 and 35 miles of travel distance on moderate assistance on flat terrain. When relying on only the throttle or traveling up steep hills the estimated range would be reduced to 12 to 20 miles. The performance characteristics are very typical of a "long haul" rider that paces themselves over many miles. For its size, 10.4 ah is reasonable. Don't expect to ride hundreds of miles on one charge but it should easily complete most commutes or weekend trips to the local park.
According to amazon, charging time ranges from 5 to 7 hours depending on starting conditions. Charging is relatively slow so consider plugging it in as soon as possible after returning home from your ride. Low self discharge ratings indicate that even when left in storage for weeks the battery will still retain usable charge levels. You don't have to worry about waking up one morning to find out your bike won't start simply because you forgot to recharge it a few days earlier. The included charger makes sure you won't have to spend additional money searching for a separate charger.
What Amazon Reviewers Are Saying
Since this product is less than 3 months old, there are currently no customer reviews available for this product since it was listed for sale January 2026. Although this may give buyers pause prior to making their final decision, ShunTongDa has developed several Lectric XP compatible batteries that have received positive buyer feedback. The comments provided by those reviewers show that they know how to create batteries specifically intended to replace the existing ones in an ebike.
Buyer reviews regarding other ShunTongDa products state that the fitment of this battery into a Lectric XP folding frame is identical to what comes stock. We cannot confirm whether this applies to this particular model however past experiences seem to suggest they maintain a good quality across all of their products. A 1 year warranty and 24/7 customer service help reduce some of the risks associated with purchasing a new battery. Most buyers appreciate being able to buy a battery at a lower cost than buying a new OEM replacement.
Who Should Buy This
If you need a new battery for your older Lectric XP Step-Thru and are unwilling to pay top dollar for a new one then you should buy this battery as it offers great value compared to what is available from OEM suppliers. This is ideal for riders who require a direct replacement that will look like a factory supplied part.
You should not buy this battery if you have a bike with a rigid frame (not folding), because the two types of frames are completely incompatible. You also shouldn't buy this battery if you need huge amounts of capacity for long rides where 30 miles isn't going to be sufficient. If you want high voltage setups for racing at high speeds then continue looking elsewhere.
Frequently Asked Questions
Will this fit my Lectric XP Step-Thru 2.0?
This was specifically built to be used on both Step-Thru model types 1.0 & 2.0. Confirm that your current battery matches these dimensions (467x100x43mm) prior to placing an order as there are some slight production variances among all Shuntongda batteries.
What type of connector is it using?
It uses a 5 pin connector identical to what you have from your original Lectric XP Battery. There is no need to add a wiring harness or cable adapters for the conversion.
Is the way I turn it on/off the same as my original Lectric XP battery?
The lock function for securing the battery is the same but the Lock also controls the "ON/OFF" of the battery. therefore, if you want to ride, you will need to keep the key inserted into the ON position. This is often confusing to many new riders who get surprised by this at their first ride.
Does this unit work with the Step-Over XP models?
While this item's description was specific to the Step-Thru model, the Step-Over models may use slightly larger battery sizes and connectors. Be sure to confirm that your current battery size and connector match those shown prior to making your purchase.
Is there a warranty included?
Shuntongda advertises a 1 year warranty with 24 hour / 7 day a week customer service. Make sure to test the battery thoroughly during your return period.
The bottom line for Lectric XP Step-Thru owners: this is the affordable path back to a working bike if your original pack is fading. Verify your dimensions, mind the key-switch quirk, and buy within the return window. Compare it against other packs on our battery comparison table, and browse the blog for more replacement guidance.
