What to know before buying

Listing details to confirm

The title lists 60V and 72V options and five capacities, while much of the detail describes 60V 40Ah. Listed dimensions also conflict: product details give 6.3"D x 14.2"W x 6.3"H, feature text gives 11*9.1*7.1 inches, and the separate 35Ah entry gives 11.8*7.3*6.9 inches. Confirm the selected voltage, capacity and exact variant dimensions. The claimed range, chemistry performance, temperature range and cycle life are not independently established here.

Who is it for?

A good fit for

Buyers matching a 60V LiFePO4 pack to a controller rated at 50A or less, after confirming the exact selected variant and physical fit.
Electric bicycle, scooter, motorcycle or tricycle owners whose system voltage and motor requirements match the selected battery.

Less suited to

Systems requiring a different voltage or a controller current above the stated 50A limit.
Buyers who need a confirmed physical size, capacity-specific range or independently established performance figures before purchase.

Aggregate ratings are positive overall, with the distribution limited to four- and five-star categories. Without written feedback, those ratings do not identify specific strengths, drawbacks or reasons for satisfaction. Buyers should assess fit and electrical compatibility using the product details rather than treating the rating as evidence for the claimed range or performance.

Frequently asked questions

Which voltage should I choose?

The listing advises matching battery voltage to the motor and controller. Its title names both 60V and 72V, so verify that the selected version matches your system.

Will it fit my battery compartment?

The page gives conflicting dimensions for the listing and different capacity variants. Measure the compartment and confirm the selected battery's exact dimensions before ordering.

What controller current does the page recommend?

It states a controller rated current of ≤ 50A and a maximum continuous discharge current of 50A. Confirm your controller's specifications and the chosen battery variant.

What is included?

The product description claims a 60V 40Ah battery, a 5A charger and Anderson plugs. The selected listing variant may differ, so verify the package contents before buying.
