Triangle Ebike Battery 72V 30Ah 80A — Ultimate High Voltage Frame Battery

The Absolute Peak of the Range

This is the highest-specification battery in the entire All4eBikes lineup — a frame-integrated lithium-ion 72V battery pack built on Grade A 21700 LG5000mAh cells, delivering 2160Wh at 72V nominal with an 80A continuous discharge current, XT90 high-current connector, and comprehensive BMS protection. Compatible with motor systems up to 5000W, this battery combines the maximum capacity available at 72V, LG’s premium 5000mAh cell chemistry, and the 80A discharge headroom needed to power the most demanding high-voltage motor builds without restriction.

2160Wh — The Maximum Energy of Any Battery in the Range

At 30Ah and 72V nominal, this battery stores 2160Wh of usable energy — the highest capacity figure of any battery across the entire 48V, 52V and 72V range. For context: the 52V 35Ah 80A triangle pack delivers 1820Wh at 52V. This battery exceeds that — 2160Wh of energy at the highest voltage platform available, delivered through the highest-rated discharge BMS in the range.

For high-output 72V motor systems in the 3000W–5000W range consuming 40–60Wh per kilometre under hard performance riding, 2160Wh delivers an estimated 36–54km per charge. For builds operating at lower average power levels — long-distance performance commuting, extended trail riding at moderate pace, or mixed urban and rural riding — the range per charge extends substantially beyond the hard-use estimate.

Grade A 21700 LG5000mAh Cells — Premium Discharge-Capable Chemistry

This battery is built on Grade A 21700 LG5000mAh cells — the highest-energy-density cell in the LG 21700 range and the same cell specification used in the top-tier 48V and 52V triangle packs. At 5000mAh per cell, LG delivers maximum energy per cell volume — enabling 2160Wh within the triangle format without requiring a physically impractical cell count. LG cell chemistry combines premium energy density with the sustained discharge capability needed for 80A operation at 72V — cells that maintain their output characteristics under sustained hard use rather than degrading under the thermal load that limits lower-specification alternatives.

Grade A selection ensures every cell in this battery pack is manufactured to the tightest internal resistance tolerances — balanced charge distribution across the full 72V series string, consistent output per cell, and uniform ageing that maintains pack capacity across the full service life. The cycle life specification confirms this premium quality: 800–1000+ cycles before the pack degrades to 80% of its original 2160Wh capacity — close to three years of daily charging at the upper end of the range.

80A at 72V — 5760W Continuous Discharge for 5000W Systems

The 80A continuous discharge current of this battery is the discharge specification that matches its 5000W motor compatibility. At 72V nominal, 80A continuous discharge delivers 5760W of sustained power draw — 760W of headroom above the 5000W motor ceiling, ensuring the BMS protection threshold stays comfortably clear of peak motor demand under the hardest possible operating conditions. Full-throttle sustained climbs, race-pace off-road riding, high-speed flat running at peak motor output — the 80A BMS handles all of these scenarios without protection trip events or current limiting that would reduce motor performance.

At 72V, the 80A BMS is the correctly proportioned discharge specification for 5000W motor systems. A 60A BMS at 72V would deliver 4320W of headroom — sufficient for 3000W systems but marginal for 5000W operation under sustained full-power demand. The 80A rating ensures this battery never becomes the bottleneck in a 5000W 72V drivetrain.

XT90 Connector and 84V Charge Cut-Off

This battery uses an XT90 connector rated for up to 90A continuous current — the correct connector specification for 80A continuous discharge with 10A of thermal headroom. At 80A operating current, an XT60 connector would be at its absolute limit, generating elevated terminal heat and accelerated contact wear. The XT90 connector maintains low contact resistance and minimal heat generation across hundreds of high-current connection cycles.

The BMS enforces the 84V cut-off automatically. Full charge from empty takes approximately 6 hours at standard charge rates, suited to overnight charging routines that deliver the full 2160Wh every morning.

BMS — Four-Layer High-Voltage Protection at 80A

Active cell balancing during charging ensures every LG cell in the 72V series string reaches the same state of charge — the critical mechanism at 72V where the longer series string makes cell balance more important than at lower voltages. The BMS operates continuously and transparently throughout the pack’s service life, requiring no user maintenance.

Triangle Format — The Correct Mounting for 5000W at 72V

This battery mounts inside the main bicycle frame triangle — placing 2160Wh of 72V stored energy at the geometric centre of the frame, between both wheels, as low as the triangle geometry allows. For 5000W 72V builds, frame triangle mounting is the correct battery position. The rapid, high-torque acceleration that 5000W at 72V produces generates powerful rearward weight transfer under hard throttle — a battery centred and low in the frame counteracts this force more effectively than any rack, rear-axle or off-centre downtube mounting position.

The durable, heat-resistant casing protects the Grade A LG5000mAh cells and 72V 80A BMS from vibration, impact and weather exposure during hard riding. Integrated straps and brackets secure the battery firmly — no drilling, no welding, no permanent frame modification.
