The Meaycoty 36V 10.4Ah is a basic silver fish pack for the price. It does include what you would want (a 4-pin base connector, a 30 amp BMS, and a 10.4Ah capacity that could support a 250W to 750W motor). The pack includes a power switch that kills drain to the motor so you don’t lose battery while your bike is stationary. That is uncommon for a package at this price point.
Specs and Charging
In addition to being a pack of cells, the battery also contains a USB port that allows riders to charge their phone, bike light(s), and other devices from the pack during a ride. Once you follow the instructions provided by Meaycoty in their manual, you should be good to go.
To ensure the pack is safe these are the major components:
- built-in 30A BMS (battery management system)
- cell balancing
- temperature monitoring
- fuse protection
- reverse polarity protection
- waterproof shell
- safety lock with anti-theft function
Additionally, Meaycoty offers a one-year warranty on free repairs and a three-month return and exchange period on quality issues. Check the Meaycoty battery on Amazon for pricing information and sales promotions currently available.
Design and Build Details
The waterproof shell with shock-absorbing interior represents a step up from many bare cell packs you’ll find at this price. The safety lock will prevent the battery from being removed from the frame unless you turn it loose first. When you do remove the battery the power switch will disconnect any remaining drain to the motor. The 30A BMS is providing ample margin for the 36V configuration. On full load from a 750W motor the BMS won’t be operating at high temperatures, which should extend the longevity of the individual components should increase.
The charge status display shows the current state of charge on the case itself. You no longer need to rely on your ebike's display or another external battery monitor to see where your battery is. The USB port is really the differentiator here. Having the ability to charge your devices directly from your ebike battery means you now have one less item to consider on longer rides. It works for phones, lights, and most USB powered accessories.
For reference, the 374.4Wh capacity of this battery will work best for short to medium distance commutes. Commuters running 250W – 500W motors will see the most Range from this battery. On higher watts the Range drops quicker but the 30A BMS doesn’t have trouble managing the load.
Who Is This battery For?
Plainly speaking this is a commuter’s pack. If your phone is also used as your GPS unit, and you’re running lights off your bike then the added feature of being able to charge those items directly off the battery is worth the cost alone. Look at the ebike battery comparison chart for specifications of similar products.
Note that since this pack is equipped with a four pin connector type, there is a chance this pack may not be compatible with all types of bike systems. Make sure to check your connectors prior to placing an order.
Anticipate 15 to 25 miles of travel time per complete discharge based on moderate levels of assistance. Weather, hills, wind resistance, and additional weight will decrease travel times significantly. Assuming a round trip of approximately ten miles each way you should have some reserve left over for errands.
Here is the problem: there are zero customer reviews for this pack. As such nobody knows how well this pack will perform after six months of regular use. If you decide to purchase one of these units take them out on easier routes prior to trusting it with your daily routine. This lack of review data is currently the greatest liability associated with this particular battery. The spec sheet and warranty appear to be satisfactory on paper. However until customers begin providing feedback on performance there will be little else to rely upon.
Commuters requiring a secondary battery or another pack for long days on a 36V system will discover that this pack serves that purpose well. The security lock and power switch allow commuters to safely remove and install the battery every day. Additionally, having a direct USB outlet into your pack means you will always have a source of power for your GPS while traveling.

When compared to larger manufacturers’ offerings of equivalent size and price this pack is very competitively priced: 30 amp BMS, USB output and lower than competing branded batteries. Although it lacks customer reviews there is still a risk involved in purchasing any product from any manufacturer. One advantage of purchasing from a smaller manufacturer like Meaycoty is that there are fewer people and thus potentially less risk of problems occurring in production. Therefore if everything operates as described in the specifications, this pack appears to represent excellent value for any consumer using a 36V system with a four pin connector.
Frequently Asked Questions
What Type of Connector Does the Meaycoty Use?
This battery comes equipped with a four pin connection type. Verify whether this matches your bike's existing connector prior to purchasing. The specification refers to this as "4-PIN-36V10.4Ah."
Can You Charge Your Phone from the Pack?
Yes, you can charge your smartphone and/or other device via USB from this pack during your ride. See shop links on the Meaycoty on Amazon page for more detail.
Which Charger Should You Buy?
Only use a charger specifically rated for 36 volt lithium-ion batteries with proper connectors. Ask the vendor if they can provide recommendations as far as chargers that meet the specifications required for charging this pack properly. Using a charger rated incorrectly (i.e., either too low or too high) can cause permanent damage to your pack, possibly creating unsafe conditions.
Is This battery Waterproof?
While it is possible that rainwater will not affect operation while you are riding in wet conditions, this pack was not made to operate underwater.
How Long Is the Warranty?
Three months of returns/exchanges and one year of free repair warranties apply to manufacturing defects under normal usage. Contact the seller through Amazon if you experience any problems.
How Much Range Do You Get?
Depending on your riding style and how hard you are pushing yourself you can anticipate getting anywhere from 15 to 25 miles per charge of the pack. Many factors contribute to actual miles traveled, including your weight, terrain difficulty, wind direction/weather etc. A more realistic estimate for average cruising speed, moderate assistance and relatively flat surfaces would be around 18 to 22 miles. Hills, headwinds and additional weight will decrease that number accordingly.
At approximately 10.4Ah this pack is intended for shorter trips only. That is acceptable. If your total round-trip distance is below 15 miles (with access to recharge at home) it makes sense to spend money on excess capacity you will never utilize elsewhere in building your bike.
