<p>LiFePO4 chemistry lithium cells have become popular for a range of applications in recent years because of being one of the most robust and long-lasting battery chemistries available. They'll last ten years or more if cared for properly. Please take some time to read these tips to make sure you receive the longest support from your battery investment.</p><p><br></p><p>The most frequent causes of premature collapse of LiFePO4 cells are both overcharging and over-discharging. A single occurrence can cause irreversible damage to the mobile, and such abuse voids the guarantee. A Battery protection System is required to ensure it Isn't possible for any cell in your package to go beyond its nominal working voltage range.</p><p><br></p><p>In the instance of LiFePO4 chemistry, that the absolute max is 4.2V per cell, even though it's recommended that you charge to 3.5-3.6V per cell, there's significantly less than 1% additional power between 3.5V and 4.2V.</p><p>Over charging causes heating within a cell and prolonged or extreme overcharging has the potential to cause a fire.</p><p>Overcharging may happen as a result of.</p><p>Insufficient the Right battery protection system</p><p>Faulty of infective battery security system</p><p>Incorrect installation of the battery protection system</p><p>At the opposite end of the scale, over-discharging can also cause cell damage. The BMS should disconnect the load if any cells are approaching empty (less than 2.5V). Cells may endure mild harm below 2.0V, but are often recoverable.</p><p>About 12v batteries the use of a low voltage cutoff takes the place of the BMS by preventing the general battery voltage going under 11.5v no cell damage should happen. On the opposite end charging to no longer than 14.2v no cell ought to be overcharged.</p><p><br></p><p>Tip 2: Clean your terminals before setup</p><p>The terminals in addition to the batteries are made from aluminum and aluminum, which over time builds up an oxide layer when exposed to atmosphere. Before installing your mobile interconnectors and BMS modules, then clean the battery terminals thoroughly with a wire brush to remove oxidation. If using bare aluminum cell interconnects, these ought to be washed too. Taking away the oxide coating will considerably improve conduction and decrease heat buildup at the terminal. (In extreme cases, heat buildup on terminals as a result of inadequate conduction was known to melt the plastic around the terminals and damage BMS modules!)</p><p><br></p><p>Tip 3: Use the Ideal terminal mounting hardware</p><p>Winston cells with M8 terminals (90Ah and up) should utilize 20mm long bolts. Cells with M6 terminals (60Ah and under) should utilize 15mm bolts. If in doubt, assess the thread thickness on your cells and ensure that the bolts will become near to but not hit the bottom of the hole. From leading to bottom, you should have a spring washer, flat washer then the cell interconnect.</p><p>Weekly or so after installation, check that all your terminal bolts continue to be tight. Loose terminal bolts may cause high-resistance connections, alerting your EV of electricity and causing undue heat generation.</p><p><br></p><p>Hint 4: Charge frequently and shallower cycles</p><p>With <a href="https://www.meritsunpower.com/bluetooth-12v-battery" target="_blank">lithium ion batteries</a>, you'll get longer cell life should you avoid very deep sparks.</p>
