72V E-Bike Battery – Samsung 30Q Triange Pack (15Ah)

Samsung 30Q 18650 cells (3000mAh)

This 72V Samsung 30Q Triangle pack is the densest powerhouse of our inventory. In the e-bike industry, 72V is the threshold where a bicycle transitions into a high-performance machine. This is for the customer who isn’t just commuting; they are looking for top-end speed and raw torque.

Includes:

• 3A lithium battery charger (aluminum)
• Comes with nine hook-and-loop fasteners that are slotted through the battery cases channel and attaches to the frame of the bike for securing
• Encased in a poly-carbonate triangle form factor battery case with cell module, BMS, & line out with XT90 connectors shrink wrapped
• BestMatch BMS provides protection against short-circuit, over-charge, over-discharge, over-current

Key Features:

• The Samsung 30Q high-discharge cells aren’t your standard commuter cells. The 30Q is a high-drain specialist, capable of 15A per cell. In this 5p configuration, it provides a massive 70A continuous output, ensuring your high-performance motor gets the peak current it needs for hill climbing and top-speed runs.

• Forget those flimsy battery bags. This rigid, molded poly-carbonate triangle case provides superior impact protection. The integrated channel for the nine hook-and-loop fasteners ensures the 17.6 lb weight is distributed evenly across your frame for maximum safety and bike handling.

• High voltage equals high heat, but the 30Q cells are designed to run efficiently at stable temperatures. Combined with our BestMatch BMS and an aluminum-cased 3A charger, this system is built to handle the thermal demands of 1,000W+ continuous power without compromising the lifespan of the pack.

Optional connector swap or adapter is available upon request.

If a vendor cannot tell you how their batteries are configured, which cells were used for the pack, or what BMS is soldered, please be very cautious supporting these businesses as not all batteries packs are created equal and can be dangerous, especially in an e-bike use case.

We’ve personally tested this setup on long, high-speed stretches, and the lack of “voltage sag” is remarkable. If you are building a CYC X1 Pro or any other high-wattage hub motor build to tackle the hilly terrain, whether you’re outside of Reston or anywhere else, this 1080Wh powerhouse is a legendary “workhorse” in the DIY community because it maintains a stable temperature even under a massive 70A continuous draw.
