These cells need to be connected together with the appropriate bus bars. Our default quantity is 1 busbar per cell, so a 4 cell pack would get 4 busbars. You will also need a battery management system, sold separately. If you need help to determine which BMS you need, feel free to contact us.
These cells are 3.2v cells and drilled & tapped for M6 hardware. We highly recommend utilizing a threaded stud, fully seated into the threads, as the aluminum terminal material is very soft and susceptible to being stripped out. Stripped terminals are not covered under warranty. We include 25mm M6 stainless steel studs and serrated M6 nuts with the cells. These terminals are optimal because your busbar will have direct contact with the large terminal material, as compared to cells with laser-welded terminals that have small contact areas and added resistance of a second and sometimes third piece of material added to the terminal.
These EVE 280Ah Batteries are brand new A-grade cells with QR codes in tact. The guaranteed capacity is at least 280ah with an internal resistance less than 0.3 milliohms. These cells have an additional margin and typically exceed their ratings. Our independent capacity testing has revealed that the cells reliably meet their rated capacity.
Typically, 4 or more of these cells will be wired in series or parallel-series with a Battery Management System (BMS) to create a 12 volt battery, 8 cells for a 24v battery, or 16 cells for a 48v battery, with a suitable BMS. They may be paralleled at a cell level to increase your overall capacity (Ah).
It is very important to use a BMS to manage these cells. Here’s Why
LiFePO4 chemistry is easily damaged by over charging, over discharging, over/under temperature, and especially low temperature charging. Use a BMS that monitors each series-connected cell (or group of parallel connected cells) and has a low-temperature cutoff.
