The Balder Power 25.9V 13Ah lithium battery is purpose-built for cordless pool cleaning robots and underwater robotic platforms where three requirements define product suitability: configurable waterproof depth to match the operating environment, sustained 50A discharge for high-power drive and brush motor systems, and quick-release mounting for efficient battery rotation in commercial pool operations.<\/p>\n

At 25.9V \/ 13Ah, this pack stores 300Wh in a 200 \u00d7 80 \u00d7 50 mm footprint weighing 1.6 kg. The 4P7S NCM cell configuration \u2014 four cells in parallel per series group across seven series groups \u2014 provides both the voltage architecture for 25.9V drive systems and the parallel cell redundancy that sustains 50A continuous discharge without individual cell over-stress. The 100A over-discharge current protection provides a secondary hard limit above the 50A continuous rating, ensuring BMS intervention before any fault condition can drive destructive current through the cell array.<\/p>\n

The IP68 multi-stage waterproof architecture is the defining specification for a pool robot battery: standard depth rating is 20 meters, with configurable depth up to 100 meters available on OEM orders. The multi-stage sealing design uses sequential independent barrier layers so that degradation of one layer does not create a direct ingress path to the cell assembly \u2014 an important reliability advantage for batteries completing hundreds of full submersion cycles per season in chlorinated or saltwater pool chemistry. The quick-release mounting system allows tool-free battery exchange, enabling commercial pool operators and rental fleet managers to maintain continuous robot deployment by rotating charged packs without interrupting cleaning operations.<\/p>\n

The V0 fire rating on the enclosure material meets the highest flammability classification in the UL 94 standard \u2014 material that self-extinguishes within 10 seconds when a flame source is removed and does not produce flaming drips. For pool cleaning robots operating in occupied environments, V0 enclosure material is the appropriate safety specification alongside the complete BMS protection suite covering overcharge, over-discharge, over-current, over-temperature, and short-circuit conditions.<\/p>","protected":false},"excerpt":{"rendered":"
