An extremely low average rating of 2.8 based on a very small number of early reviews is a serious red flag, and warrants much more attention than simply ignoring it. A 2.8 star rating is a very low average rating, however, it is possible the battery itself is of good quality. The average rating of 2.8 does indicate that, on average, the first few users of the product were unhappy with it and therefore, it would be smart to investigate why they were unhappy with the battery before spending money on it. The Topone 36V 11Ah battery delivers 396 watt-hours with a 20A to 30A BMS, compatibility across 100W to 1000W motors, and a multi-voltage listing that covers 36V and 48V variants. This review examines the possible reasons for the low rating and the potential use case for this pack.
The 2.8-Star Rating: What It Tells You
A 2.8-star average rating on a small amount of reviews is unusual for a non-defective battery listing. Most legitimate battery products have an average rating of 3.5 to 4.5 stars. A sub-3-star rating on a small sample size of reviews implies that a reasonable number of initial purchasers had bad experiences.
Common low-rating causes for budget 36V packs include capacity that does not meet stated Ah rating (battery arrives weaker than claimed), BMS issues that cause premature cutouts under normal loads, compatibility problems with specific controller types, and quality control issues affecting some production units. Because of the limited number of reviews, it is difficult to discern which of these patterns are driving the 2.8 average rating for this specific listing. An honest assessment is that potential buyers should be more cautious when looking at this listing than a listing that has an average rating of 4.0 or above.
A low rating on a small number of reviews is more volatile than a low rating on 50 or 100 reviews. A bad experience out of eight reviews produces a lower average than a bad experience out of fifty reviews. If this listing continues to add reviews, the average will either normalize towards the middle, improve due to better production batches or validate the warning signal. Checking the current review count and the most recent reviews before ordering will provide more up-to-date context than the snapshot provided above. If the listing has grown to twenty plus reviews with an improving average, the early signal may have been from a bad production batch that was subsequently corrected. If the average has held at 2.8 or dropped further across a larger review base, the warning has been confirmed and alternatives are now the clearer recommendation.
Check the current pricing and actual reviews on Amazon prior to making your decision. Reading the negative reviews specifically will tell you more than the star average alone.
Specs: 396Wh, 20-30A BMS, 100-1000W
The 11Ah at 36V produces 396Wh. With a BMS of 20A to 30A, the Topone 36V 11Ah is suitable for most short urban commutes under 15 miles per charge. The BMS for this battery is noted to be 20A to 30A, which is a good specification for a 36V battery. However, the battery also lists compatibility for 100W to 1000W motors. The 20A BMS at 36V will produce a max output of 720W continuous and the 30A BMS at 36V will produce a max output of 1080W. Therefore, if you plan to use a 1000W motor, you will need to verify that you receive the 30A BMS version of the battery. Confirm your BMS specification prior to purchasing the battery.
External Box Format and Mounting
The Topone 36V 11Ah is an external box battery designed for 36V systems. It can be mounted using standard methods such as rack straps, triangle bags or custom brackets. Because weight for a 36V 11Ah pack is minimal, triangle bag mounting is easy.
Better Alternatives to Consider
If you are shopping for a 36V battery, you may want to look at other batteries available at the same capacity tier. The LOLRKO 36V 10Ah battery is available and has a 4.2-star average with similar specs at 360Wh for a small difference in capacity. Another option is the HAYAEnergy 36V 16Ah LiFePO4 battery, which offers LiFePO4 chemistry at 576Wh with 5-star early reviews. Both represent more reliable data points at comparable capacity tiers.
For a specific 36V 11Ah requirement, the battery comparison table allows you to filter by voltage and compare alternatives. If no significantly higher rated option exists for your needs, the Topone may be worth a closer examination of the actual review content before deciding.
Who Might Buy This
You would typically want to purchase this battery only after carefully examining all of the current reviews, understanding why the low ratings were issued, and determining whether any of those issues impact your specific use case. If you find that there are no better rated 36V 11Ah batteries available, or if cost is the primary factor, then the specified specifications (396Wh, 100-1000W) for this battery are within the expected parameters for this capacity class.
If you are looking for confidence in your decision to purchase a 36V 11Ah battery, you could compare the Topone battery to the other 36V batteries listed on the battery comparison table that have large numbers of reviews and average ratings of 4.0 or greater. Additionally, if you can move to a 36V 10Ah or 12Ah battery instead, the LOLRKO and RANSYRI options are both available and have positive user reviews.

Frequently Asked Questions
Is 2.8 stars enough to disqualify a battery? While not automatically disqualifying, it is a serious red flag. Examine the actual reviews of the product rather than just the overall average. If the complaints relate to the battery being incompatible with a connector or having a different capacity than stated for a particular use case that does not apply to you, then the risk profile is different than if the reviews state that the units arrive dead upon arrival or rapidly lose capacity.
What is the difference between a 20A and a 30A BMS on this listing? At 36V, 20A will allow for a continuous output of 720W, while 30A will allow for a continuous output of 1080W. If you plan to use a 1000W motor, you will need to ensure that you get the 30A BMS version of the battery. For motors less than 720W (most 36V commuter setups), either BMS version will work. Verify which amperage you are receiving for your specific order prior to relying on compatibility.
Is 396Wh sufficient capacity for a daily commute? For short commutes of 12 miles round trip on relatively flat terrain, 396Wh is sufficient. Depending on your terrain, weight, and assist level, 396Wh will deliver approximately 12 to 20 miles per charge. If you ride farther or on hillier routes, you may want to consider 15Ah or 20Ah options in the 36V tier for additional buffer.
Why is 36V 11Ah an unusual capacity? There are many 36V batteries offered at various capacity levels including 10Ah, 12Ah, 15Ah, and 20Ah. 11Ah is not commonly used for 36V. The battery will yield approximately 396Wh. The range difference between 360Wh (10Ah) and 396Wh (11Ah) is about 1 to 2 miles.
Is this compatible with 48V controllers? No. This is a 36V battery. The listing states that it is a 36V/48V multi-variant product. Verify that you receive the proper voltage when you place your order. A 36V battery on a 48V controller will perform much worse than intended. Also, the charging voltage will not be compatible. Use the exact voltage required for your system.
Should I purchase a different 36V battery? Generally, yes. The 2.8-star rating indicates that there is a higher than normal risk of experiencing one type of problem compared to other alternatives that have higher averages, like the LOLRKO 36V 10Ah at 4.2 stars or the HAYAEnergy 36V 16Ah LiFePO4 at 5 stars. If you have carefully reviewed the current reviews for this product, identified the reasons for the low rating do not pertain to your specific use case, and are seeking a budget-friendly alternative, then the stated specifications (396Wh, 100-1000W) are typical for this capacity class.
