Cameron Sino Replacement Battery for Ecovacs Deebot Ozmo 900/901/905/920/930/937 3400mAh

Direct replacement for Deebot Ozmo 900 series

This Cameron Sino lithium-ion cell is built to the original specifications for Ecovacs Deebot Ozmo 900, 901, 905, 920, 930 and 937 robot vacuums. It restores the 3400mAh capacity and 14.4V output that the machine expects. The fully decoded chip communicates with the robot exactly like the factory pack. Owners of other Ecovacs models or different brands will need a different part number.

Thermal behaviour and power delivery

The pack uses standard lithium-ion chemistry rated at 48.96Wh and includes over-charge, over-discharge, over-voltage and short-circuit protection circuits. In normal cleaning cycles the battery runs at the robot's designed voltage without extra heat or noise beyond what the original cell produced. No active cooling or fan is involved. Users who need higher runtime than 3400mAh provides cannot meet that need with this pack.

Physical fit and installation aids

Dimensions are 132.40 x 37.00 x 21.50mm and weight is 188.6g, matching the original battery cavity. The package includes shock-absorbing foam for transit protection. Numerous online installation videos demonstrate the straightforward connector swap. The supplier advises two to three full charge-discharge cycles for optimal performance and warns against disassembly, fire, water or storage above 60°C. Builders needing a different form factor or connector layout must look elsewhere.
