Reention DP9 High-Capacity Downtube Battery

Built for serious range and clean integration, the Reention DP9 casing is one of the largest removable downtube battery platforms available for 18650 cells.

BLUETOOTH BMS now comes standard to enable cell level monitoring.

With support for up to 91 cells, this pack allows you to push capacity further than typical Hailong-style batteries — without sacrificing mounting simplicity.

All builds use plastic cell separators, except 60V MAX configuration, uses double wrapped cells adhesively bound to fit the 96 cells.
