Raleigh Dover 360 Compatible Battery 25.2V 18000mAh

Raleigh Dover 360 / Dover De Luxe P8 XXL — 25.2V Li-ion Replacement Battery

This 25.2V 18000mAh (453.6Wh) lithium-ion pack replaces the original battery on the Raleigh Dover 360, Dover De Luxe P8 XXL, Dover HS, Dover XXL LTD, and 12 additional Dover variants. It matches the voltage rail and connector spec of the OEM unit. Dimensions are 272.50 × 153.50 × 103.80mm — check your current pack before ordering.

• Dover platform compatibility: All listed Dover variants share the same 25.2V battery architecture, connector pinout, and BMS communication protocol. Swapping between models in this range does not require rewiring or adapters.
• Bench tested on actual hardware: We cycled this pack through simulated motor-draw loads reflecting sustained hill climbing. The BMS held voltage above the cutoff threshold under continuous draw and balanced cells within spec across discharge cycles.
• Winter storage recharge tip: After any period of cold storage, connect the charger and let it trickle for at least 30 minutes before riding. Cold Li-ion cells carry higher internal resistance — pushing a fast-charge or full motor load immediately can cause lithium plating on the anode, which permanently reduces the number of usable charge cycles.

Sustained climbing draws peak current from the pack for longer than flat riding. If the BMS detects cell voltage dropping below its low-cell cutoff — typically around 2.5V per cell under load — it trips and cuts motor output to protect the cells. This is normal BMS behaviour, not a faulty battery. To reduce trip frequency, lower assist level on long climbs to reduce sustained current draw, or allow the pack to rest for 60 seconds at the top before continuing.

If the pack has self-discharged below the charger's acceptance threshold — typically under 20V for a 25.2V Li-ion pack — most chargers will not initiate a charge cycle. The cells are not necessarily dead. Connect the charger and leave it for 30 minutes without interrupting it; many chargers will begin a low-current recovery charge once the BMS registers a minimum cell voltage. If the charger light remains off after 30 minutes, check that pack voltage reads above 18V with a multimeter before assuming cell failure.
