15x Lithium Polymer 3.7V 2520mAh Cells

Here are boxes of 15 Genuine U46P313 Rechargable Lithium Polymer Batteries! For this price you get 15 batteries (just $0.56 per pack). So many customers have built battery projects with these cells in the past few years. Inside each battery is a 3.7v 2520mAh 9.32Wh cell and a 3a BMS. You can charge and discharge through the positive and negative terminals so these are batteries with a single cell BMS which makes assembling a battery very safe. Most customers are simply trimming some of the plastic off and soldering lead wires directly to the + and - connectors. Some are using a folded piece of nickel to slide in like a blade. You can expect around 90% capacity as these were only cycled a few times.

Single cells with a BMS works like a smart cell level fusing. Simply charge each pack up to 4.2v, make your series and parallel connections, then add an overall pack BMS and you are ready to go with a very safe and long lasting battery pack. Perfect for many applications with 1c discharge abilities and 0.5c charge abilities. Those specs are good for most applications.
