The BtrPower 36V 10Ah LiFePO4 ebike battery is part of a multi-variant listing from BtrPower that covers voltages from 36V all the way up to 72V and capacities from 10Ah to 60Ah. The 36V 10Ah variant reviewed here delivers 360Wh of total capacity using LiFePO4 (lithium iron phosphate) cells, which are known for their longer cycle life and improved safety compared to standard lithium-ion cells. BtrPower includes a charger, XT60 connectors, and cable straps in the box. The listing became available in October 2025 and currently has no customer reviews, making this a true first-adopter purchase. BtrPower backs it with a 30-day return policy and 12-month warranty.
Specs and Build Quality
The BtrPower pack runs at 36V nominal with 10Ah capacity for a total of 360Wh. What makes this battery stand out from most of the ebike batteries on the market is the LiFePO4 cell chemistry. LiFePO4 cells are widely considered the safest lithium battery type available. They are fire-resistant, non-toxic, and do not contain hazardous heavy metals. The only downside is slightly lower energy density compared to standard lithium-ion. While the battery will provide the same amount of power as a lithium-ion pack with the same watt-hour rating, it will weigh a little more and be slightly larger.
Physical specs
The battery measures 11.1 x 5.9 x 2.8 inches and comes as a standalone pack without a specific frame mount. The box includes the battery, a 3A fast charger, an XT60 male plug, an XT60 male to T plug adapter, two adjustable cable straps for securing the battery to the frame, and a manual. The cable straps provide flexibility in how the battery is secured to accommodate a variety of different frame designs, though the configuration will not look as sleek as a purpose-built frame-integrated battery.
BMS and motor compatibility
The 36V 10Ah variant comes with a 20A BMS that provides protection against short circuits, overcharge, and over-discharge. At 36V, a 20A continuous discharge supports up to 720W of output. BtrPower rates this variant for motors from 250W to 550W, which covers a good range of 36V ebike motors. The BMS also helps extend the cycle life of the LiFePO4 cells, which BtrPower claims can reach 1500 cycles or more before noticeable capacity degradation.
Form Factor and Compatibility
This is a generic pack-style battery with XT60 connectors, meaning it is not designed for a specific bike model or frame mount. The included XT60 to T plug adapter gives you two connector options, which covers most DIY ebike setups and many commercial controllers. If your ebike uses a different connector type, you would need a separate adapter.
Before ordering, you need to confirm that your ebike controller runs on 36V and draws 20A or less of continuous current. The motor wattage should be 550W or lower for this variant. BtrPower offers the same listing in multiple voltage and capacity options, so if you need a higher voltage or more capacity, you can select a different variant from the same product page.
The adjustable cable straps included in the box allow you to mount the battery to your frame, downtube, or rear rack, though you may want to consider a dedicated battery bag or case for a more secure installation on rougher terrain.

Real-World Range Estimates
At 360Wh, the BtrPower LiFePO4 battery should deliver roughly 15 to 25 miles of range depending on motor size, terrain, rider weight, and pedal assist level. BtrPower claims 15 or more miles without pedaling, which aligns with typical consumption rates for a 36V system running a 250W to 500W motor. On flat terrain with moderate pedal assist, lighter riders may push past 25 miles. Heavier riders using full throttle on hills will see range drop toward 15 miles or less.
The key advantage of LiFePO4 chemistry shows up over time rather than on any single ride. With a claimed 1500 cycle lifespan, this battery should maintain good capacity for 3 to 5 years of regular use, which is roughly double what most standard lithium-ion ebike batteries offer.
What Amazon Reviewers Are Saying
The BtrPower 36V 10Ah LiFePO4 battery currently has no customer reviews on Amazon. The listing became available in October 2025, so it has been on the market for several months without accumulating buyer feedback. While it is common for new products to receive few or no reviews initially, the lack of feedback does mean potential buyers will be relying solely on manufacturer claims to evaluate the product before purchasing.
BtrPower is a known brand in the ebike battery space with other listings that have established review histories. Their 30-day return policy and 12-month warranty provide some protection if the battery does not meet expectations.

Who Should Buy This
The BtrPower 36V 10Ah LiFePO4 battery is best suited for DIY ebike builders or riders with existing 36V setups who want the safety and longevity benefits of LiFePO4 chemistry. The 1500 cycle lifespan is a significant advantage over standard lithium-ion batteries, and the incombustible nature of LiFePO4 cells provides added peace of mind. The included charger and XT60 connectors make it a fairly complete kit for getting started.
The lack of customer reviews means you are taking a chance on a product without any real-world feedback. The generic pack form factor with cable strap mounting may not appeal to riders who want a clean, integrated look. And at 360Wh, the capacity is on the lower end for riders who need long-range capability. If those tradeoffs work for your situation, the BtrPower LiFePO4 pack offers a chemistry upgrade that most competing ebike batteries at this price point do not provide.

Frequently Asked Questions
What is the difference between LiFePO4 and standard lithium-ion? LiFePO4 (lithium iron phosphate) cells are considered the safest lithium battery chemistry. They are incombustible, have a longer cycle life (typically 1500 or more cycles versus 500 to 800 for standard lithium-ion), and do not contain heavy metals. The tradeoff is slightly lower energy density, meaning LiFePO4 batteries tend to be larger and heavier for the same capacity.
Does this battery come with a charger? Yes, BtrPower includes a 3A fast charger in the box along with XT60 connectors, an XT60 to T plug adapter, adjustable cable straps, and a manual.
What motors is this battery compatible with? The 36V 10Ah variant is rated for motors from 250W to 550W. The 20A BMS supports up to 720W of continuous output, but BtrPower recommends staying within the 550W range for optimal performance and battery longevity.
How do I mount this battery to my bike? The battery comes with two adjustable cable straps that allow you to secure it to your frame, downtube, or rear rack. For a more secure installation, you may want to use a dedicated battery bag or mounting bracket.
How many charge cycles will this battery last? BtrPower claims the LiFePO4 cells will last 1500 cycles or more before noticeable capacity degradation. With daily charging, that translates to roughly 4 to 5 years of regular use.
Are there other voltage options available? Yes, this is a multi-variant listing. BtrPower offers the same battery in 36V, 48V, 52V, 60V, and 72V options with various capacity choices. You can select the voltage and capacity that matches your ebike setup from the same product page on Amazon.
