OP4015 contains 1.5Ah cells. 1C rate = 1.5Ah/1hr = 1.5A. 6.15A > 1.5A
OP4020 contains 2.0Ah cells. 6.15A > 2.0A
Cell capacity is half that of the battery pack, since the design is two cells in parallel.
Each string of ten cells receives half the charge current, or 6.15/2 = 3.08A.
OP4026 is rated 2.6A, so the cells are 1.3Ah. 3.08A > 1.3A
OP40261 is rated 2.6A, so the cells are 1.3Ah. 3.08A > 1.3A
OP4030 is rated 3.0A, so the cells are 1.5Ah. 3.08A > 1.5A
OP40401 is rated 4.0A, so the cells are 2.0Ah. 3.08A > 2.0A
OP40501 is rated 5.0A, so the cells are 2.5Ah. 3.08A > 2.5A
OP40601 is rated 6.0A, so the cells are 3.0Ah. 3.08A > 3.0A
Cell capacity is one third that of the battery pack, since the design is three cells in parallel.
Each string of ten cells receives one third the charge current, or 6.15/3 = 2.05A.
OP40602 is rated 6.0A, so the cells are 2.0Ah. 2.05A > 2.0A
OP40751 is rated 7.5A, so the cells are 2.5Ah. 2.05A < 2.5A
I recommend using the OP406A sparingly or not at all on batteries under 6.0Ah in capacity. |
