Top Quality Li-ion Pouch Cells from Enerdel (Enertech), and Kokam for demanding EV applications
The cells have been capacity checked and the ampere/hours are printed as well as the internal resistance value.
The Enerdel Cells have the following details:
The cells were made for a project that was cancelled and were disposed of to a large Chinese distributor. The cells were made in mid-2013 but were kept in storage at below 10℃ and the cells were maintained regularly at recommended storage voltage. The cells are as good as can be and fully guaranteed. Lifecycle for these cells are at least 2000 and we have been provided data by a contact at Enertech to product data that is closest to our cells. Due to the size and weight being slightly larger with our cells, we can safely assume that they will be better than the specifications below.
Ampere/hour tests prove the point that our cells are better than what is shown in the data. For improved lifecycling the data suggests using 4.10V CV charging voltage. However, our cells can be charged at the standard 4.20V even though 4.10V would considerably increase the lifecycles of the cell. You may use the lower voltage which will decrease the run time as the cell would charge to about 90% of its capacity
