SKU: 32475438853 Category:

           <p> Description:</p> <p> <br /> 1. The module name: 4 string lithium battery protection board<br /> 2. The modular nature: polymer lithium battery protection board<br /> 3. Overcharge detection voltage: 4.25 &plusmn; 0.025V<br /> 4. Overcharge release voltage: 4.15 &plusmn; 0.05V<br /> 5. Over discharge detection voltage: 2.50 &plusmn; 0.08V<br /> 6. Over discharge termination voltage: 3 &plusmn; 0.1V<br /> 7. Overcurrent: 20-30A<br /> 8. Working current: 15A (natural cooling:10A, plus the heat sink:15A, the maximum instantaneous current:30A)<br /> 9. Termination conditions:the release of protection condition then automatic recovery, without activation (optional charger to activate)<br /> 10. Main functions: the overcharge protection function, overdischarge protection, short-circuit protection, over current protection.<br /> 11. Working temperature: -40~+85 degrees (high temperature environment and please strengthen radiating)<br /> 12. Connection: welding output<br /> 13. Module size: 50mm*22mm*4mm<br /> <br /> Applications</p> <p> <br /> The protective board can be used as the nominal voltage of 14.4V, 14.8V, 16.8V four series of polymer lithium battery group, four series of 18650 lithium batteries as overcharge and over discharge, short circuit protection. Without the activation function in the power application for high instantaneous current,and in inverter application for avoid false triggering protection.So it will use more convenient.<br /> <br /> Note:No part design on the back, can be attached to the heat sink to ensure high current work situation for a long time.</p>  <p> <img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB16rjLSFXXXXbeaXXXq6xXFXXXz.jpg" /></p> <p> <img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1ROeqaZrrK1RjSspaq6AREXXaf.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1wHiha5rxK1RkHFCcq6AQCVXaa.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1dwuta5YrK1Rjy0Fdq6ACvVXa7.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB15n5raZ_vK1RkSmRyq6xwupXaB.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1cmeqa6DuK1RjSszdq6xGLpXa5.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1tVCha.vrK1RjSspcq6zzSXXab.jpg" /></p>    <p> Buyers show</p> <p> <img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1Iuu4hrwrBKNjSZPcq6xpapXaU.jpg" /></p> <p> <img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1jd.qSFXXXXbBXXXXq6xXFXXX3.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1dqr0SFXXXXXPXVXXq6xXFXXXj.jpg" /><img class="img-responsive" src="https://ae01.alicdn.com/kf/HTB1CMTTSFXXXXbQXVXXq6xXFXXX9.jpg" /></p>   <em>USD 1.39</em>/piece<em>USD 8.57</em>/piece<em>USD 6.99</em>/piece<em>USD 3.40</em>/piece<em>USD 1.32</em>/piece<em>USD 13.99</em>/piece<em>USD 1.65</em>/piece<em>USD 3.23</em>/lot
