72V 20Ah Triangle E-Bike Battery
Description
72V 20Ah Triangle E-Bike Battery – High-Voltage Lithium Battery Pack for High-Performance Conversion Kits
The 72V 20Ah triangle battery is the top solution for riders who want high power, high speed and extended range on performance electric bikes. The 72V high-voltage configuration combined with a 20Ah capacity (about 1440Wh) provides the energy needed for high-power hub or mid-drive motors.
The triangle design is made specially for the bicycle frame: the narrow profile and optimised shape allow mounting directly in the frame triangle, without affecting ground clearance or upsetting the bike's geometry. Weight is distributed centrally and low, which means better stability in corners and at high speed compared with a battery mounted on a rack.

Why the 20S configuration matters for performance
The 20S configuration means 20 cells connected in series, each contributing about 3.6–4.2V to the total pack voltage. This architecture allows the 72V voltage needed by high-power controllers and motors (2000W and 3000W), giving more torque and a higher top speed than 48V or 52V batteries.
BMS and cell protection
The battery has a 60A BMS, built with premium LG/Samsung cells, which monitors in real time the voltage of each cell, the temperature and the operating current, preventing overcharge, excessive discharge and imbalance between cells. The casing is IP65 certified, protecting against light rain and splashes in normal use.
Which Kits It Is Optional On
MTX kits of 2000W and 3000W
The 72V voltage gives power margin for fast acceleration and a high top speed, without running at the edge of the current limit.
Mid-Drive Conversions
Extra torque when pedalling with assistance, suited to hilly routes or intensive electric MTB.
High-Speed DIY Projects
An energy reserve for long distances without power compromises, for custom eBike builds.
Installation, Maintenance and Safety
Mounting Steps
- At 20S and ~8 kg, ask for help with installation if you are working alone on a tall frame
- Fix the battery in the triangle with both straps, checking that it does not touch the chain or the derailleur
- Connect the XT60/XT90 connector, suited to the high current of this 72V pack
- Before the first start at full power, check the LCD and the displayed voltage
Maintenance
- As the highest-voltage battery in the range, check the tightness of the mounting straps monthly
- Do not repeatedly discharge below 20% — at 20S, cell imbalance appears more easily
- For storage longer than 2 weeks, keep 40–60% capacity at room temperature
- Avoid charging at temperatures below 0°C — at high voltage, the risk of cell damage rises
72V 20Ah: for the 2000W and 3000W kits
It is the highest-energy battery in the whole range, 1440 Wh, and is linked to the 2000W and 3000W kits. The estimated range is 55–70 km, and at 7.5–8.5 kg the page suggests getting help with installation.
