Assembled Product Dimensions (L x W x H)

<p>The Innovative 2S 3S 4S Lithium Battery Balance Board With 100Ma Balancer Current is designed for lithium batteries with a nominal voltage of 3.7V and a full voltage of 4.2V, including 26650 and polymer lithium batteries without size limitations. The 2S version measures 45 by 15 by 3.4mm and supports charging voltages between 8.4V and 9.0V, with a continuous discharge current up to 20A and charge current up to 10A. The 3S board is sized at 15 by 30 by 2.4mm and operates at 12.6V with a 100mA balancer current, suitable for 2000 to 4000mAh battery packs. The 4S version, made from resin and metal, measures 20 by 30 by 2.4mm and supports 16.8V with the same balancer current. This balance board cannot replace a lithium battery protection board as it lacks overcharge and over-discharge protection but works alongside it to balance charging. It is important to ensure proper cooling during use and to match battery packs carefully for effective balancing.</p>
