The example of a large-scale cell damage caused by overcharge

The damage was caused by using a high-speed charger (30A) designed for charging 16 cells with a pack of just 15 cells without proper balancing and management. The voltage of some of the cells reached high above the max voltage

Test report:4 pcs of LFP200AH cells discharged at 280A (1.4C)

Due to improperly managed charging, a set of cells was exteremely overcharged, resulting into cells shape deformation. The purpose of the test is to verify the performance of the cells after they have been pressed back to th

High Power DC Charging Connector

High Power DC Charging Connector

This is a . The MAX power DC 600V/150A per single high-current pin. Six additional pins for communication datalines.

Balancing cells with RT-BMS

Balancing cells with RT-BMS

The test data shows the charge and discharge results for 4 pieces of the using the RT-BMS for management.

During the charge it is possible to see how the individual cells are balanced till they reach nearly identical voltage.

Testing the Akumon

Testing the Akumon

The yellow LP battery is the traction battery. The black battery (the board battery) provides the current for the external relays connected to the Akumon board. The two blue 12V relays disconnect the charger (over voltage) and the load (low voltage).

The LiFePO4 12V battery serial connection cycle tests

Please of our performancetests of 12V 20AH batteries. This is a demonstrattion of high speed discharge @40A and high speed charge @30A. If you have any questions and/or comments, please let us know.

ThunderSky 160AH capacity test

ThunderSky 160AH capacity test

Please see another test by JRR Nortec tetsing equipment. Base on this report, you can see the capacity of the 160Ah cell reaches the total of 165.4Ah. This makes 103% capacity level.
