Rad Power owners know how painful factory battery prices can be when the original battery fades after a few years or gets stolen right off the bike. OEM replacement often costs nearly as much as the bike itself. The DICHOU 48V 20Ah LG Cell aftermarket pack addresses the issue of factory battery prices with a 960 watt-hour pack made to fit Rad Power bikes like the RadRunner 2, RadExpand 5 Plus, Radwagon 4, Radwagon 5, and RadCity. The pack uses LG 5200mAh cells in a 13S4P configuration with a 40A BMS to provide more capacity than the factory battery at approximately half the price.
DICHOU is a Shenzhen Lian Pai Yuan Technology Co. brand that makes aftermarket ebike batteries, primarily for popular ebike brands such as Rad Power. This particular listing is the LG Cell variant of the DICHOU pack, utilizing brand-name LG cells rather than generic cells found in other DICHOU listings. Brand-name cells like those made by LG are generally considered to offer better energy density, longer cycle life, and more consistent performance than generic cells.
Specs and Value
The main specifications here include 48 volts nominal, 20 amp-hours, and 960 watt-hours. The 13S4P configuration utilizes 52 individual LG 5200mAh pouch cells, and the 40A BMS provides protection for overcharge, over-discharge, short circuit, and overcurrent. DICHOU states that the pack is rated for motors ranging from 200W to 1500W, which covers all types of hub motors, and also mid-drive and conversion kit configurations.
Physical specs
The battery weighs 4.74 kg (approximately 10.5 pounds) which is typical for a 20Ah lithium-ion pack utilizing name-brand cells. The battery features XT60 connectors for the discharge port, which is a common, reliable, and widely-used connector in the ebike community. If your Rad Power bike utilizes a different connector type, you will probably need to purchase an adapter or perform a connector swap. The battery comes with a mounting base plate that fits most bike frames, a key lock for securing the battery, and an LED battery indicator for tracking the remaining charge on the battery.
Prior to shipping, DICHOU performs testing of each battery pack through a complete charge and discharge cycle, which they document as including short-circuit, overcharge, crush, and extrusion safety tests. A charger is provided with the battery, though the charger amperage was not specified in the listing.
BMS and motor range
At 40 amps continuous on a 48V system, the theoretical peak output of the 40A BMS is 1920 watts. As stated earlier, the BMS is rated for 200W to 1500W motors, so this battery will easily handle any motor configuration on a Rad Power bike. Rad Power bikes utilize 500W and 750W hub motors, which are within the BMS comfort zone.
The 40A rating provides plenty of headroom beyond what Rad Power motors consume, so the BMS will rarely cut out the pack under normal riding conditions, even during prolonged hill-climbing or full-throttle use. That additional buffer may help to extend the life of the battery.
Form Factor and Compatibility
As mentioned previously, the DICHOU 48V 20Ah pack is designed for Rad Power bikes: RadExpand 5 Plus, Radwagon 4, Radwagon 5, RadRunner 2, and RadCity. The battery comes with a mounting base plate that mounts to the frame, and the battery clips into the plate with the key provided. Several Amazon reviewers confirmed that this battery fits the original Rad Power battery tray with little-to-no adjustment to the mounting bolts.
However, compatibility is not guaranteed. The XT60 discharge connector utilized in the DICHOU 48V 20Ah means that you may need to verify whether your Rad Power bike utilizes the same connector, or be prepared to swap to a compatible connector. One reviewer indicated they loosened the original mounting bolts and slid the tray down to accommodate the new battery. Another reviewer indicated a straightforward swap. The takeaway is that fitment is very probable on Rad Power bikes, but minor adjustments may be required depending upon your exact model and year.
In addition to Rad Power, the listing also mentions compatibility with general ebike conversion kits and motor brands such as Bafang and Voilamart. The 48V output and XT60 connectors make it suitable for a wide variety of 48V systems, though you will always need to confirm your controller voltage and connector type prior to purchasing.
Real-World Range
Due to the 960Wh capacity of the DICHOU 48V 20Ah, this battery will easily out-range most factory Rad Power batteries. With a standard Rad Power 750W hub motor and moderate pedal assist on flat terrain, 35 to 50 miles per charge is a realistic estimate. Heavy throttle use or hilly terrain would reduce that range to 20 to 35 miles. Additionally, several Amazon reviewers have provided estimates based upon actual riding experiences: one rider estimated he obtained 40 to 60 miles on trails, while another rider estimated he rode 25 miles on his Rad Power bike while using only 35 percent of the battery, which suggests a total range of 72 miles.
For commuters completing 10 to 25 mile round-trip commutes, this battery will likely allow for a full workweek without daily charging. The 20Ah capacity places the DICHOU 48V 20Ah at the upper-end of capacity compared to other 48V 20Ah options for Rad Power replacement batteries, and you can compare this battery to other similar options on our comparison table to evaluate the relative price per watt-hour.
What Amazon Reviewers Are Saying
The DICHOU 48V 20Ah LG Cell Battery has an average rating of 4.2 stars on Amazon with 21 reviews. The majority of the reviews were extremely positive with several 5-star reviews and a number of detailed reports from Rad Power users.
One Rad Rover 5 user described how they obtain much greater voltage and mileage compared to their old factory battery, and called it a great value and performance. Additionally, they complimented the seller for being very responsive to their pre-purchase and post-purchase inquiries. Another RadRunner 5 user replaced their 5-year-old factory battery and rode 25 miles in 30 mph winds, and only used 35 percent of the charge. That same rider also complimented the battery by stating it fit onto the original battery tray with only minor adjustments to the mounting bolt positions.
A trail rider stated he obtained 40 to 60 miles per charge using pedal assist for knee recovery, and described the installation process as easy. Perhaps the most glowing review came from a person that purchased two DICHOU batteries after their Rad Power batteries were stolen. That person stated that the DICHOU batteries were half the price of the OEM batteries and better, with longer battery life, a digital display, and a USB port. After six months of usage, he stated the batteries lasted forever on one charge.
One reviewer gave it two stars, noting that their daily ride initially consumed only 15 percent of the charge but increased to 65 percent of the charge after a month of every-day use, indicating some loss of capacity. While this is something to keep in mind, it is only a single data point among overwhelmingly positive reviews.
Who Should Buy This
The DICHOU 48V 20Ah LG Cell Battery is designed for Rad Power owners that require either a replacement or upgrade battery at a fraction of the OEM cost. At roughly half the price of a factory Rad Power battery, you receive 960Wh of capacity from LG cells with a 40A BMS capable of supporting any Rad Power motor, with excess power for other components on the bike. Additional features on the battery include a key lock, LED battery gauge, and an included charger equaling or surpassing the capabilities of the OEM battery.
While it is ideal for RadRunner 2, RadExpand 5 Plus, Radwagon 4 and 5, and RadCity owners, due to the 48V output and XT60 connectors, the DICHOU 48V 20Ah pack can also be used in other 48V ebikes and conversion kits. In addition, the overwhelmingly positive comments from actual Rad Power owners regarding their experience with the DICHOU pack, combined with the utilization of LG cells providing a higher quality platform than generic alternatives, suggest that this pack meets its claims.
If you need a different voltage or form factor, please refer to our battery comparison table for other options. If you are uncomfortable changing connectors or modifying a mounting tray, contact the seller to confirm that your exact Rad Power model is supported prior to making a purchase. For most Rad Power users seeking a large-capacity aftermarket battery with LG cells, the DICHOU pack will meet expectations.
