Triangle Ebike Battery 52V 25Ah — 1300Wh Mid-Power Frame-Integrated Battery

1300Wh in a Frame-Fit Triangle — The 52V Mid-Power Sweet Spot

This battery brings together the key qualities most riders are actually looking for in a conversion build: enough energy for meaningful real-world range, a voltage level that genuinely upgrades performance over standard 48V systems, a cell chemistry proven across hundreds of charge cycles, and a form factor that integrates cleanly into any standard diamond-frame bicycle. At 1300Wh total energy — calculated from 52V multiplied by 25Ah — this battery delivers comfortable range for extended commutes, long trail rides and touring applications without the weight, cost or complexity of moving up to a 72V high-discharge pack.

The 52V platform is an increasingly popular choice among e-bike builders precisely because of where it sits in the performance spectrum. Running a 48V-compatible motor on 52V — as most 48V-rated hub motors and Bafang mid-drive systems safely support — produces noticeably stronger acceleration, a higher top speed and better sustained output under load compared to a true 48V supply, while remaining comfortably within the operating range of standard 48V controllers and motor systems.

Grade A 21700 EVE Cells — Consistent Quality Across Every Cycle

This battery is built around Grade A 21700 EVE 5000mAh lithium cells — a cell chemistry and grade specification that directly defines the pack’s quality above lower-cost alternatives built from ungraded or off-spec cells:

The 800–1000+ cycle life specification means this battery maintains at least 80% of its original capacity after 800 to over 1000 full charge-discharge cycles under normal operating conditions — a durability figure that represents years of regular use before any perceptible reduction in riding range.

48V and 52V Compatibility — One Battery, Two System Generations

One of the most practically useful specifications of this battery is its compatibility with both 48V and 52V eBike systems. This dual compatibility means the pack works seamlessly with the largest installed base of conversion motors and controllers currently in use — every 48V-rated motor and controller in the All4eBikes range, as well as systems specifically designed around 52V nominal voltage.

For riders running a battery pack alongside a Bafang mid-drive motor, the 52V configuration is particularly well suited. The BAFANG BBSHD Mid Drive 1000W and the BAFANG BBS02B 750W CAN-BUS both operate at 48V and benefit from the additional voltage headroom this battery provides — producing stronger initial acceleration, a higher no-load speed and improved hill-climbing performance compared to a true 48V supply.

For hub-motor builds in the mid-power range, the Rear Hub Motor 48V-52V 1500W is an excellent motor pairing for this triangle battery, drawing well within the pack’s 40A continuous discharge rating while benefiting from the 52V performance uplift.

40A Continuous Discharge — Matched to Mid-Power Motor Systems

The 40A continuous discharge rating is deliberately matched to the current demands of mid-power hub-motor and mid-drive systems in the 1000W–2000W range. At 52V and 40A continuous, this battery sustains up to 2080W of continuous power output — sufficient for the vast majority of conversion builds that pair 48V or 52V motors with standard riding conditions including hill climbing, mixed terrain and sustained highway-speed riding.

The 40A continuous rating also works in favour of the pack’s long-term cell health. Operating cells at a moderate C-rate generates less heat per cycle, reduces internal resistance growth over time and contributes directly to achieving the upper end of the 800–1000+ cycle life rating.

BMS, Connector and Casing — Built for Reliable Daily Use

This battery incorporates a full Battery Management System providing protection against overcharge above 58.8V, over-discharge, overcurrent above the peak rating, overheating and short circuits. This comprehensive BMS protection layer ensures the triangle battery operates safely across the full range of riding conditions — from cold morning starts to sustained summer climbs — and preserves cell health across the rated cycle life by preventing operation outside safe voltage and temperature parameters.

The XT60 connector is a widely used, reliable high-current connector rated for the discharge levels this battery pack operates at, compatible with the XT60 power leads supplied with mid-power controllers and systems across the All4eBikes range. The durable, heat-resistant outer casing protects the cells and BMS from dust, moisture and everyday physical impacts. A purpose-made Bag for Triangle Battery is also available for transport and storage protection.

Frame Compatibility and Installation

This battery mounts inside the main triangle of a standard diamond-frame bicycle — the space enclosed by the top tube, down tube and seat tube. The rubber securing straps allow tool-free installation and removal for on or off-bike charging. The pack’s triangle geometry is designed to fit a wide range of standard frame sizes without modification, and its placement inside the frame triangle keeps the battery weight low and centred for optimal handling.
