Brand

<p>The 2S 3S 4S 100mA Lithium Battery Balance Board 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 product comes in different sizes: 45x15x3.4mm for the 2S standard version, 48x20x3.4mm for the 2S balancing version, 15x30(40,50)x2.4mm for the 3S version, and 20x30(40,50)x2.4mm for the 4S version. It supports charging voltages from 8.4V to 16.8V, with continuous discharge currents up to 20A and charge currents up to 10A, depending on cooling conditions. The balance board is made of resin and metal, weighs 3g, and is suitable for battery packs between 2000-4000mAh. The package includes one PCB board for 2S, 3S, or 4S configurations. Note that this balance board does not replace a lithium battery protection board as it lacks overcharge and over-discharge protection. It works by discharging the first fully charged cell to balance the pack and should be used alongside a protection board. Proper cooling and battery matching are recommended for optimal performance.</p>
