Typical Lithium Ion Polymer Battery Technical Data

Nov 07, 2019 by admin Category: Industry News 0 comments

The lithium ion polymer battery range includes 200 models which offer designers increased flexibility when it comes to developing next generation portable devices. The lithium polymer battery cells come in low profile, high energy density packages for fitting into those tightest of spaces. With this technology advance, cells have been made lighter providing reduction in the overall end product weight. For an overall product solution cells or Battery Packs can be factory assembled with Protection Circuit Modules (PCM).
