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

Why the 20S configuration matters for performance
The 20S configuration means 20 cells connected in series, each contributing approximately 3.6–4.2V to the pack's total voltage. This architecture enables the 72V required by high-power controllers and motors (2000W–5000W), delivering greater torque and higher top speed compared to 48V or 52V batteries.
BMS and cell protection
The battery integrates a 60A BMS, built with premium LG/Samsung cells, which monitors each cell's voltage, temperature and operating current in real time, preventing overcharging, excessive discharge and cell imbalance. The casing is IP65 certified, offering protection against light rain and splashes in normal use conditions.
What Type of Conversions It's Recommended For
2000–5000W Hub Motors
The 72V voltage provides a power margin for rapid acceleration and high top speed, without straining the current limit.
Mid-Drive Conversions
Increased pedal-assist torque, suitable for hilly routes or intensive electric MTB use.
High-Speed DIY Projects
Energy reserve for long distances with no power compromise, for custom e-bike builds.
Installation, Maintenance and Safety
Installation Steps
- Check dimension compatibility with the space in the frame
- Secure the battery with the mounting straps
- Connect respecting polarity and connector type
- Check the LCD before first use
Maintenance
- Avoid discharging fully below 20%
- Store at 50–70% capacity for long periods
- Charge in a ventilated space, never unattended
- Avoid temperatures below 0°C or above 40°C
