Ozroll E-Port Controller 14.4V Ni-MH Replacement Battery

Ozroll E-Port / ODS / Smart Drive Smart Control 10 — 14.4V Ni-MH Replacement Battery (15.200.001)

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Ozroll E-Port Controller, ODS Controller, and Smart Drive Smart Control 10. These are wireless remote control units used to operate automated gates, doors, and barriers. When the original battery depletes, the remote loses the ability to send open/close commands — this battery restores that function.

• E-Port, ODS, and Smart Control 10 compatibility: All three remotes run on the same 14.4V Ni-MH cell pack, share the same connector pinout, and use the same BMS charge handshake. One replacement covers the full range without modification.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the controller, confirmed the BMS accepted the cell pack without fault codes, and verified the remote transmitted gate commands across the full charge range.
• First-use charge on crane and gate remotes: Ni-MH cells ship at storage voltage — typically 60–70% charge. Before using this remote in a gate or barrier application, run a full charge cycle first. A partial charge on first use sets a false capacity reference in some Ozroll controllers, causing premature low-battery warnings.

Remote showing low battery immediately after swap

Ni-MH cells leave the factory at storage voltage, not full charge. The Ozroll controller reads cell voltage on boot and flags low battery if it sees anything below roughly 12.5V at rest. A freshly installed pack sitting at storage voltage will trigger this warning even though the cells are not faulty. Connect the controller to its charger for a full cycle before drawing any conclusions about the replacement battery. After a full charge, resting voltage should sit at or above 13.5V.

Ozroll remote not powering on after months of infrequent use

Gate and barrier remotes often sit unused for months between service intervals. Ni-MH cells left in deep discharge — below approximately 1.0V per cell — can trigger BMS lockout, where the protection circuit disconnects the pack entirely to prevent cell reversal. Plugging the charger in for 30 to 60 minutes applies a trickle current that nudges cell voltage above the lockout threshold and allows the BMS to re-engage. If the pack does not recover after 60 minutes on charge, the cells have reversed and the battery needs replacement. A healthy pack will show at least 10V at the terminals after that first 60-minute trickle.
