Here are boxes of 15 Genuine U46P313 Rechargeable Lithium Polymer Batteries! For this price you get 15 batteries. 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 or more 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.
