High Current Charging and Discharging Report for WINA Cells
The purpose of the test is to verify the performance of the LiFePO4 cells in high
current discharge and charge conditions:
1) What are the discharge characteristics for 1C to 3C currents?
2) How will the individual cells perform under these tests?

The Test Report: Comparison of the 36AH LiFePO4 pack with 12V/40AH SLA battery
The purpose of the test report is to show the specification of the LiFePO4 battery made of WN-36AH cells.
The advantages of the WN-36AH cells
- professionally produced LiFePO4 cells
- stability during high current discharge
- the discharge with long flat discharge area (3.30V to 3.10V)
- aluminum case for protecting the cell
- no overheating or heat release during operation

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.
The DC motor setup
Agni DC motor + Evnetics Soliton Jr installed for the eCarTec demo setup.
CE declaration of conformity for the Winston Battery products
Each and every TS battery consists of hundreds of single plate cell layers connected in parallel.

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.
