High Current Charging and Discharging Report for Lithium (LiFeYPO4) Cells

How will a LiFeYPO4 cell behave after 13000 cycles of high speed charge and discharge?  Will the battery overheat or have any other malfunction? Will the battery age and lose its capacity?

Study the results in the The LiFeYPO4 cell test data after 13,000 cycles

GWL Tech Report - Long time balancing – a slow way to damage the lithium (LiFePO4) cells

Lithium cell can be destroyed by over charge. The damage by the slow overcharge at balancing level is the most common reason of a gradual damage to the lithium cells.  Please study the GWL Technology Report to learn bore about this kind of slow overcharge. The document also gives a practical advice by means of several tips to avoid the damage to the cells by changing the way of cell balancing.

Dynamic-BMS for 12 Volt Lithium Yttrium Iron Batteries (obsolete product)

The Dynamic Battery Monitor System (BMS) with balancing function is the first worldwide solution to manage series of 12V Lithium Yttrium Iron batteries (LFYP batteries).  The LFYP batteries made by Thunder-Sky are the only direct 12V lithium solution on the world market.  Now you can use 12V lithium batteries instead of many small 3.2V cells.  Read more in Product Development Report 2009/11/01
