A 48V 12Ah pack with a slide-in 5-pin base at 140 bucks is hard to find. Most batteries in this price range use generic wire connectors or require a separate mounting plate. The Q RQTEBAT builds the base and lock straight into the package, and includes both TX60 and TX90 extension cables for wiring flexibility.
Specs and Build Quality
Total capacity of this pack is 576Wh (48 x 12), which will provide approximately 15 to 25 miles of range based on a typical 500W hub motor configuration, terrain, and assist level. Physical specifications are 15.3 by 4.8 by 4.9 inches, and it weighs 10.7 pounds.
The housing of the battery is designed to be a fully waterproof enclosure, providing no issues related to rain riding. Included is a two key safety lock, an LED light on the side to indicate charge status, and a power button to reduce standby draw when the battery is not actively being charged or discharged. Also included is a 54.6V 3A charger that can fill the pack from zero in about 4 to 5 hours.
Mounting is accomplished via a slide-in baseplate with a five pin connector. As with many Chinese made ebike battery packs, this type of connector simply slides onto the mounting bracket attached to the bike frame and then locks into position. The baseplate and all required mounting screws are supplied.
BMS and Safety Features
Protection against overcharge, over discharge, over current, and short circuits are all handled through the 25 amp BMS. In terms of maximum wattage rating for a 48 volt system, 25 amps equates to approximately 1,200 watts peak, allowing for safe operation of both 500W and 750W motors, with additional room for increased power requirements.
As stated within the original listing description, the cells used are grade A with a minimum expected lifespan of greater than 1,500 cycles. Additionally, they mention utilizing anti-seismic bracket technology, essentially securing the internal cells to prevent movement due to road shock. While many specs pages may seem to downplay this aspect of a battery's design, loose internal connections can become a common point of failure for lower cost packs after traveling several hundred miles of rough terrain.
Disconnecting the battery's output when the bike is parked is facilitated by the power switch. This prevents any potential phantom drain from occurring through the controller or display. Four bars represented by the LED indicator represent the approximate level of charge remaining within the pack.
Amazon Reviews
Amazon currently lists four reviewers giving this product a perfect score. Keep in mind this represents a very limited number of reviewers, therefore consider the feedback accordingly. All reviewers thus far have praised the quality of the mounting system, along with the ease of installation. Both reviewers have complimented the inclusion of the extension cables as an added convenience, since they allow users to connect the battery using either the TX60 or TX90 adapters, depending upon their specific controller needs.
Additionally one reviewer mentioned how well the battery was able to fit their particular bike frame using the included mounting bracket. Another reviewer mentioned the location of the power switch allows them to easily reach it while still seated on their bike. None of the reviewers thus far have reported any defects or issues related to performance.
Keep in mind there are limitations associated with having such a low number of reviews. A perfect 5 star review average from only four reviewers does little to inform us regarding the long term reliability of the battery. The 12-month warranty provides some protection if issues arise down the road.
Who Is This Battery For?
An ideal candidate for budget conscious consumers seeking a 48V battery equipped with a mounting system that attaches securely to their ebike frames. The slide-in base with five pin connector is cleaner than strapping an aftermarket battery to your frame bag, and the included mounting bracket eliminates the need to spend time searching for compatible hardware.
However, this battery is not suitable for consumers requiring minimal weight or maximum range per dollar. While the 12Ah capacity and 576Wh energy storage provides ample range for shorter commutes under 15 miles, those requiring extended ranges would benefit from purchasing a 17.5Ah or larger capacity pack. You can compare other 48V options on the comparison table to see what fits your range needs.
Frequently Asked Questions
What type of charger comes with the Q RQTEBAT battery?
Included with this purchase is a 54.6V 3A fast charger. This charger takes approximately 4 to 5 hours to recharge the entire pack from empty once plugged in. The charger features a universal barrel-style connector that mates with the charging port on the pack.
Is the Q RQTEBAT waterproof?
Yes, the case is fully waterproof rated for rain riding. This means you can continue to ride your ebike in wet weather conditions without concern for damaging your battery due to moisture exposure.
What does the five pin base connector accomplish?
The five pin connector provides both primary power delivery as well as any communication lines between the battery and controller or display. Many ebike displays utilize these additional pins as a method for displaying real-time information concerning battery charge levels. If your ebike does not utilize this five pin connector, you can always use the provided TX60 or TX90 extension cables.
Can I use this pack with my 52V controller?
No. The voltage rating for this pack is specified at 48V (the pack actually reaches roughly 54.6 volts at full charge). Attempting to operate this pack with a controller designed for 58.8 volts full charge may result in potentially causing damage to either component, or exhibit abnormal operating behaviors.
Which motors can I operate with this battery pack?
Up to 1000W motors are supported. The pack contains a BMS that has an output capability of up to roughly 1200W peak. This gives you plenty of margin for a 500W or 750W motor, with some headroom for short bursts.
How do I mount this battery to my ebike?
The included baseplate mounts to your frame with the provided screws. The battery slides onto the baseplate from above and locks into place with the safety lock. A slide rail system keeps it secure during riding. The whole process takes about 10 minutes with basic tools.
Is the 25A BMS enough for a 1000W motor?
The 25A BMS handles about 1200 watts peak on a 48V system, which is enough for a 1000W motor under normal riding conditions. However, sustained full-throttle uphill riding might push past the limit. If you plan on aggressive riding, consider checking our other battery reviews for packs with higher BMS ratings.
What other Q RQTEBAT options are available?
Check current pricing on Amazon to see what's in stock. The listing sometimes offers different capacity versions of the same 5-pin base design.
