The 720Wh on a water-bottle bracket at a recorded 189 was the fitment play for small and step-through frames, and the ASIN is now retired while the mount format lives on across the family. The 30A math covers 1000W motors with real headroom. Riders whose frames have bottle bosses and no other mount option win here. Everyone else has better formats.
Bottle bosses and the mount trade
The pack bolts to standard bottle cage threads, which solves the step-through problem: no downtube, no rack, just two threaded holes and a clean silhouette. It sits low and centered, so it steers better than a rack mount of the same weight. You can pop it off in seconds to charge indoors, which matters for apartment dwellers who can't run a cord to a bike locked outside.
The format's ceiling is capacity. Fifteen amp-hours is near the top of what a bottle-sized bracket carries, and the pack's width is the limit. Two threaded holes decide everything: if your frame doesn't have them at standard spacing, the format is closed to you. Keep the bolts tight, because a rattling bracket works loose over rough roads.
Installation takes ten minutes and a hex key. Bolt the bracket to the cage threads with a drop of thread locker, slide the pack until it clicks, and pull it off once to learn the release. Ride the first week with the bolts checked after every wet ride. The pattern that kills this format isn't the hardware failing, it's the hardware loosening quietly and the owner not noticing for a month.
The frame carries the load, so thin or old tubes deserve a check before you hang a pack on them. It's a clean-look choice that asks a bit more care than a clamp-on. The weight rides where a water bottle would, which is exactly why it handles well.
The 30A math and what 720Wh buys in miles
The 30A BMS at 48V supports about 1440W of continuous draw, which covers a 1000W motor with headroom for climbs. The 200W floor in the claim is marketing noise, because every motor draws current the moment it spins. What matters is the ceiling, and this one sits comfortably above the motors this format targets.
The pack holds 720Wh, and about 612 of those are usable at the 85% rule. Ride light pedal assist at fifteen to twenty-five watt-hours per mile and you'll cover between twenty-four and forty-one miles. Throttle-heavy riding at thirty to forty Wh per mile drops that to fifteen or twenty miles. Hills, weight, and winter pull the numbers down.
The included 2A charger needs about six hours for a full fill, which makes overnight charging the routine. The USB port charges a phone on breaks and does nothing for your range. Neither fact changes the format's math, but both belong in the daily-use picture.
Cold weather deserves its own planning note with a pack this size. Lithium cells deliver less in winter, and a 612-usable-Wh pack that gives 35 summer miles may give 25 in January. Store the pack indoors overnight, snap it onto the bike just before you leave, and the cold penalty shrinks. Riders who leave the pack on the bike in an unheated garage lose the biggest chunk of winter range to storage temperature, not to the ride itself.
The family today: buying this slot after the retirement
The live family brackets this pack: a 10Ah sibling at 109.99, a 13Ah at 159.99, and a 52V 15Ah at 229.99. The recorded 15Ah at 189 sat between the 13Ah and the 52V 15Ah in value, so the slot it filled still exists, just under different ASINs. The same 58.8V 2A charger serves the whole line, and a six-hour fill is the family routine.
Check four things on any current listing before you order: the bracket bolt spacing against your frame's cage threads, your motor's wattage against the 1000W ceiling, the charger amperage, and the return window. The retired listing's review pool is unverifiable, and the recorded 4.8 is the only rating signal that survives. The battery table sorts the whole market by price per watt-hour so you can see where each family member lands.
There is also a bracket-vs-bag comparison worth making before you commit. A water-bottle pack wins on looks, weight placement, and theft resistance, because a thief must unbolt it rather than unhook it. A triangle bag wins on capacity, since the whole frame triangle is available for cells. If your rides are short and your frame is pretty, the bracket makes sense. If you need range above 40 miles, the bag holds what this format cannot.
Who should buy this format, and who should spend differently
Buy this format if your frame has bottle bosses, your motor stays between 750 and 1000W, and indoor charging matters. It is the cheapest way to put a real pack on a frame that can't carry anything else.
Skip it if a downtube or rack mount is available to you, because both carry more capacity per mounting point. Skip it if your motor exceeds 1000W, because the 30A BMS ceiling is real. The Vodipower 25Ah folding pack is the mount-format story at triple the capacity, the 52V VISET sibling stays in-brand at higher voltage, and the 48V 14Ah power pack is the external-box alternative.

Frequently Asked Questions
Will this battery fit my ebike frame?
It bolts to standard bottle cage threads, so measure the spacing between the two holes first. Without those threads, the format doesn't attach at all.
How much range can I get on one charge?
Between 24 and 41 miles on pedal assist, or 15 to 20 miles throttle-heavy, based on the 85% usable rule and standard consumption bands.
Can this battery handle a 1000W motor?
The 30A BMS supports about 1440W continuously, which covers a 1000W motor with headroom on climbs.
How long does it take to charge?
The 2A charger needs about six hours for a full fill of 720Wh, so overnight is the routine. The family shares the same charger.
Where can I buy this model now?
The listing is retired, but the family's 10Ah and 13Ah packs are live. Verify bracket spacing and the return window on whichever size you pick.
Does the USB port work while riding?
The port charges a phone from the main cells, and it works whether the pack is on the bike or on the charger. Draw is small enough that a phone top-up barely moves the range math, but on a small 720Wh pack the share it takes is bigger than on a large pack. On this size, keep phone charging for breaks.
