Grade A 21700 LG 5000mAh cells · 100A continuous discharge · Supports 72V systems up to 8000W · 800–1000+ cycle life · XT90 connector · 12-month warranty
This is the highest-energy battery in the All4eBikes triangle battery range and one of the most capable 72V lithium ebike battery packs available at this price point. With a total energy capacity of approximately 2160Wh — calculated from its 72V nominal voltage and 30Ah capacity — this pack provides the kind of range and sustained output that high-power electric bike builds demand. Whether you are running a 3000W hub-motor conversion, a 5000W off-road machine or a high-performance mid-drive system, it has the energy reserve and discharge capability to power your build through extended, demanding riding sessions without compromising performance.
The triangle form factor is a deliberate engineering choice, not merely an aesthetic one. By shaping the battery to fit inside the main triangle of a bicycle frame — the space bounded by the top tube, down tube and seat tube — it keeps the pack’s weight low and centred on the bicycle. This placement dramatically improves weight distribution compared to rear rack or seat post-mounted batteries, preserving the handling feel of the bicycle and reducing the destabilising effect of carrying a heavy pack at a high or rearward position on the frame.
This battery is built around Grade A 21700 LG 5000mAh lithium cells — a specification that separates it from the budget-grade batteries that flood the conversion kit market. Understanding why cell quality matters so fundamentally helps explain why 72V battery performance varies so dramatically between similarly specified packs from different sources:
Only cells that pass the manufacturer’s highest quality threshold are classified as Grade A. They demonstrate consistent capacity, matched internal resistance and verified cycle life across the full cell batch. Grade B and ungraded cells — commonly used in lower-cost packs — show higher internal resistance, greater capacity variance and shorter practical cycle life from the first charge cycle.
The 21700 cell format (21mm diameter, 70mm length) offers a higher energy density per cell than the older 18650 format. This allows the pack to achieve its 30Ah capacity in a physically compact triangle case that fits a wide range of standard frame sizes without modification.
LG is one of the most respected lithium cell manufacturers in the industry. The LG M50 21700 cell at 5000mAh per cell is a proven, widely validated chemistry that delivers consistent performance across hundreds of charge cycles, making it the preferred cell for serious high-discharge battery builds.
Built on Grade A LG cells, this battery maintains usable capacity for 800 to over 1000 full charge-discharge cycles under normal operating conditions — equivalent to several years of regular use before any meaningful capacity degradation becomes apparent in riding range.
The 100A continuous discharge rating is one of this battery’s most important specifications for high-power conversion builds. Discharge current — measured in amps — determines how much power the battery can deliver to the motor continuously without the BMS throttling output, the cells overheating or the voltage dropping under load. At 100A continuous on a 72V system, this battery can sustain a theoretical peak output of 7200W — more than sufficient to power the most demanding motor systems in the All4eBikes range without restriction.
This battery incorporates a professional-grade Battery Management System that provides comprehensive protection across every aspect of operation, monitoring and protecting against the five most common causes of lithium battery failure and degradation:
The BMS charges this battery via an 84V charging voltage input, with a full charge from empty completed in approximately 6 hours under standard charging conditions.
This triangle form factor is designed to fit inside the main frame triangle of standard diamond-frame mountain bikes, hybrid frames and custom build platforms. The four rubber securing straps on the pack allow for tool-free installation and removal — the battery mounts directly inside the frame without brackets, custom mounts or permanent fixings. The XT90 connector is a high-current rated connector well suited to the 100A discharge capability of this pack, and is compatible with the XT90 power leads supplied with all high-power motor controllers in the All4eBikes range.
For riders who need a different voltage or capacity in the same triangle format, the Triangle eBike Battery 72V 30Ah 80A offers the same capacity at a lower peak discharge rating and a more accessible price point. The Triangle eBike Battery 52V 30Ah is the recommended choice for 52V motor systems including the BAFANG BBSHD Mid Drive 1000W. For 48V builds, the Triangle eBike Battery 48V 35Ah provides outstanding range at a lower operating voltage. A purpose-made Bag for Triangle Battery is also available to protect the pack during transport and storage.
Every Triangle eBike Battery 72V 30Ah 100A purchased from All4eBikes is covered by a 12-month warranty covering manufacturing defects in the cells, BMS and casing, alongside a 30-day return window for complete purchase confidence.
