Triangle Ebike Battery 48V 35Ah — 1680Wh Premium LG Cell Frame Battery

1680Wh — The Maximum Capacity 48V Triangle Pack

At 35Ah and 48V nominal, this battery stores 1680Wh of usable energy — the highest energy capacity available in any 48V triangle battery format. For a 48V motor system consuming 15–20Wh per kilometre under mixed conditions, 1680Wh delivers an estimated range of 84–112km per charge from a mid drive system in the 250W–350W range. For high-output hub motor and mid drive systems in the 750W–2000W range, real-world range remains substantial enough to cover full-day riding, extended delivery routes and multi-stage touring on a single charge.

The step from the Triangle Ebike Battery 48V 30Ah at 1440Wh to the 35Ah at 1680Wh represents a 16.7% increase in stored energy at the same LG5000mAh cell specification, same 45A discharge rating, and same triangle format — a meaningful additional reserve that makes a real difference on the longest routes and in the most demanding riding conditions.

Grade A 21700 LG5000mAh Cells — The Benchmark Cell Specification

This battery is built on Grade A 21700 LG5000mAh cells — the same premium cell specification used in the 30Ah format, now delivering 1680Wh at 35Ah. LG 21700 cells represent the premium tier of cylindrical lithium-ion cell manufacturing — 5000mAh per cell at the 21700 format delivers the highest energy density per cell available in commercial lithium-ion production. Grade A selection means every cell is manufactured to the tightest internal resistance tolerances — consistent performance across every cell, even ageing across the full pack, and reliable BMS management through every charge cycle.

The cycle life specification reflects this cell quality: 800–1000+ cycles before the pack degrades to 80% of its original 1680Wh capacity. At one full charge per day, that represents close to three years of daily use at the upper end of the range.

45A Discharge Current — Sustained Power for 2000W Systems

The 45A continuous discharge current of this battery is the discharge specification that matches its 2000W motor compatibility. At 48V nominal, 45A continuous discharge delivers up to 2160W of sustained power draw — providing 160W of headroom above the 2000W motor ceiling under continuous operation. This headroom is critical for sustained high-output riding: the BMS does not trip into current limiting under normal hard riding conditions including sustained steep climbs at full throttle, hard acceleration from standstill under load, and extended high-speed flat running.

XT60 Connector — High-Current Interface

The XT60 connector on this battery is rated for the 45A continuous current demands of this pack — delivering reliable, low-resistance current flow across hundreds of connection cycles without contact degradation. XT60 is the most widely supported high-current connector format in the DIY e-bike conversion market, compatible with the majority of motor controllers available without adapter modification. The connector’s positive-lock design ensures secure contact during riding — no vibration-induced disconnection, no intermittent power delivery, no connector failures under sustained high-current operation.

Triangle Format — Weight, Aesthetics and Integration

This battery mounts inside the main bicycle frame triangle using integrated straps and brackets — no drilling, no welding, no permanent frame modification. This mounting position delivers three practical advantages over downtube and external battery formats:

The durable, heat-resistant outer casing protects the Grade A LG cells and BMS electronics from vibration, mechanical impact and weather exposure during normal outdoor use.

BMS — Comprehensive Four-Layer Protection

Active cell balancing during charging ensures every LG cell in the series string reaches the same state of charge — the mechanism that maintains capacity consistency across 800–1000+ cycles and prevents early cell divergence. The BMS operates continuously and transparently, requiring no user maintenance throughout the pack’s service life.

Charging — 54.6V Cut-Off, 7-Hour Standard Charge

This battery charges to a full cut-off voltage of 54.6V in approximately 7 hours from empty at standard charge rates. The BMS terminates charging automatically at 54.6V regardless of charger output — no overcharge risk, no need to monitor the charging cycle. Standard 7-hour overnight charging delivers a fully charged 1680Wh pack every morning.
