The Triangle Ebike Battery 52V 28Ah is a high-capacity, premium-cell frame-integrated lithium-ion battery pack delivering 1456Wh of stored energy from Grade A 21700 LG4800mAh cells — engineered for 48V and 52V motor systems up to 2000W. With a 50A continuous discharge current, an 800–1000+ cycle life, comprehensive BMS protection, and the frame-mounted triangle profile that keeps weight centred and build aesthetics clean, the Triangle Ebike Battery 52V 28Ah is the high-capacity 52V triangle battery for builders who want LG cell quality, 52V performance, and the range of 1456Wh combined with 50A discharge headroom for demanding motor applications. This is the triangle battery 52V that delivers on every metric serious builders care about.
At 28Ah and 52V nominal, the Triangle Ebike Battery 52V 28Ah stores 1456Wh of usable energy — a substantial step up from the 1040Wh of the 20Ah format, and very close to the 1440Wh of the 48V 30Ah triangle pack, but delivered at 52V for sharper motor performance across the operating range. For a 52V motor system consuming 15–20Wh per kilometre under mixed conditions, 1456Wh delivers an estimated range of 72–97km per charge from a mid drive system in the 250W–350W range. For high-output hub motor and mid drive systems in the 750W–2000W range, the 1456Wh capacity still delivers full-day range figures that cover extended commuting, cargo delivery runs, and long recreational rides on a single charge.
The step from the Triangle Ebike Battery 52V 20Ah at 1040Wh to the 28Ah at 1456Wh represents a 40% increase in stored energy at the same 52V platform, same LG cell chemistry, and same 50A discharge rating — a major additional reserve that makes a real difference on the longest routes and under the heaviest motor loads. This is the triangle battery for ebike builds that demand both range and power without compromise.
The Triangle Ebike Battery 52V 28Ah is built on Grade A 21700 LG4800mAh lithium-ion cells — a premium cell specification from one of the world’s most respected lithium-ion manufacturers. The 21700 format delivers higher energy density per cell than standard 18650, enabling 1456Wh within a manageable triangle physical footprint without compromising cell quality or cycle performance. LG cell chemistry is recognised across the e-bike, EV, and professional battery industries for its consistency, thermal stability, and long-term capacity retention — and Grade A selection means every cell in this battery pack is manufactured to the tightest internal resistance tolerances. Consistent internal resistance means balanced charge distribution across every cell in the series string, even ageing across the full pack, and reliable BMS management through every charge cycle.
The cycle life specification confirms this quality: 800–1000+ cycles before the pack degrades to 80% of its original 1456Wh capacity. At one full charge per day, that represents over two years at the conservative end and approaching three years at the upper range — a triangle battery 52V built for genuine long-term ownership and serious daily use.
The 50A continuous discharge current of the Triangle Ebike Battery 52V 28Ah is the discharge specification that correctly matches its 2000W motor compatibility at 52V. At 52V nominal, 50A continuous discharge delivers up to 2600W of sustained power draw — 600W of headroom above the 2000W motor ceiling, ensuring the BMS protection threshold remains well clear of normal hard riding current demands including sustained steep climbs under full load, hard acceleration from standstill, and extended high-speed running. The 50A BMS rating is specifically important at 52V because elevated voltage increases the peak current demand at the battery terminals compared to equivalent 48V operation at the same motor power — the 50A rating accommodates this correctly where a 40A or 45A BMS would be closer to its limits under the same motor conditions.
For high-power hub motor builds that demand this level of sustained discharge, the E-Bike Conversion Kit 2000W BLACK is the directly compatible motor system — 2000W brushless hub motor, Smart Sine Wave 45A controller, and 27.5-inch MTX wheels, pairing cleanly with this 52V battery‘s 50A discharge capability. For the full range of compatible conversion kits, visit the Conversion Kit category page.
The triangle battery for ebike operates at 52V nominal with a full charge voltage of 58.8V — delivering its peak voltage at the start of every ride for maximum motor performance and sharpest throttle response. The 58.8V full charge voltage is significantly higher than the 54.6V of a fully charged 48V pack, producing noticeably sharper acceleration and higher peak power from any 48V or 52V compatible motor system. As the pack discharges through its operating range, voltage declines gradually while the BMS enforces the low-voltage cut-off to protect the LG cells from deep discharge damage. The BMS terminates charging automatically at 58.8V, eliminating overcharge risk with any compatible charger. The Triangle Ebike Battery 52V 28Ah charges fully in approximately 6 hours from empty — suited to afternoon or overnight charging routines depending on daily usage patterns.
The integrated BMS in the Triangle Ebike Battery 52V 28Ah provides four layers of active protection across every charge and discharge cycle. Overcharge protection terminates charging at 58.8V. Over-discharge protection enforces the low-voltage cut-off to preserve LG cell chemistry. Overcurrent protection limits discharge current under fault conditions, protecting both the cell pack and the connected motor controller from damage. Short-circuit protection provides immediate system shutdown on wiring or connector failure. Active cell balancing during charging ensures every cell in the series string reaches the same state of charge — the critical mechanism that maintains capacity consistency across 800–1000+ cycles. All four protection layers operate continuously and transparently, requiring no user maintenance.
The Triangle Ebike Battery 52V 28Ah mounts inside the main bicycle frame triangle using integrated straps and brackets — no drilling, no welding, no permanent frame modification. Mounting the battery pack inside the frame triangle places its 1456Wh of stored energy at the geometric centre of the bicycle, between both wheels and as low as the triangle geometry allows. This is the optimal mass position for handling balance and low centre of gravity — the converted bicycle tracks and corners naturally rather than feeling rear-heavy, top-heavy, or unbalanced under hard riding. The triangle format also fills the empty void inside the frame, giving the conversion a clean, factory-built appearance that external battery mounting cannot achieve.
The durable, heat-resistant outer casing protects the Grade A LG cells and BMS electronics from vibration, mechanical impact, and weather exposure during normal outdoor use. The XT60 connector is rated for the 50A continuous current demands of this triangle battery 52V, delivering reliable, low-resistance current flow without contact degradation across hundreds of connection cycles. Verify your frame triangle internal dimensions against this battery’s physical profile before ordering — the 28Ah format is physically larger than the 20Ah equivalent and requires adequate frame triangle volume.
The Triangle Ebike Battery 52V 28Ah is compatible with most 48V and 52V eBike systems and DIY conversion setups, supporting motor systems rated up to 2000W. It is equally suited to high-output hub motor conversions, BAFANG BBSHD 1000W mid drive systems, and custom performance builds where sustained high-power output capability and long range are both design priorities.
