18650s in Parallel or Series? : r/batteries

Like the others have said running batteries in parallel is no different than having a single cell with larger capacity, it''s the series configurations you need to worry about. One thing I''ll emphasize is that regardless of series or parallel lithium ion are very touchy in charging so make sure you get a 1s dedicated charging board. As long as the charging current of the board isn''t more ...

18650 Battery Pack Calculator and Planner

Battery Configuration: Decide whether you need to connect the cells in series, parallel, or both to achieve the desired voltage and capacity. Series connections increase voltage, while parallel connections increase capacity.

18650 in series or parallel in battery bank, which approach is better

Not all batteries work great in parallel and or in series, this has a big impact on the charging circuitry. Looking at all of the factors I make my choice. Assuming the batteries are the same, the capacity increases by the amount the additional battery adds regardless if it is in series or parallel. Assume (keeping it simple) we have 2 3Volt ...

How to connect old 18650 different capacity cells as a 2S2P pack?

By connecting the 1152 mAh and 871 mAh cells in parallel you would get the equivalent of a 2023 mAh cell, while connecting the 1121 mAh and 931 mAh cells in parallel would yield the equivalent of a single 2052 mAh cell. You could then put these two parallel groups in series, to yield a slightly imbalanced 7.4V 2023 mAh pack.
