Built with the Reention DP-2170-4C Cases (very strong and durable).

These packs are using the newer variant of lithium ion cell, the 21700 cell.

They are named this because the cells use a 21mm diameter, 70mm length cell, as opposed to the previous 18650 cell (18mm diameter, 65mm length).

These packs benefit from being slightly more energy dense. They are also slightly wider which allows them to fit more easily into bicycle frames because they don't need to be as tall to get the same amount of energy.

36 Volt batteries come with a 4 Amp charger, 48V come with a 3A charger.

Nice battery packs and due to them having only 39 or 40 cells (instead of 70 cells in the 18650 models) they are easier to manufacture and thus have a slightly better price for their given energy capacity.
