وصف المنتج
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.
At 25.9V / 13Ah, this pack stores 300Wh in a 200 × 80 × 50 mm footprint weighing 1.6 kg. The 4P7S NCM cell configuration — four cells in parallel per series group across seven series groups — 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.
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 — 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.
The V0 fire rating on the enclosure material meets the highest flammability classification in the UL 94 standard — 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.

الميزات والمزايا
✅ 🌊 IP68 Multi-Stage Waterproof: 20m Standard, Configurable to 100m
The Balder Power 25.9V 13Ah pack uses a multi-stage sealing architecture with sequential independent barrier layers validated to IP68 standard. Standard production units are depth-rated to 20 meters — the operational depth of the majority of commercial pool cleaning robots. For OEM customers requiring deeper-rated packs for underwater hull cleaning, subsea inspection, or specialty robot platforms, depth rating is configurable to 100 meters within the same electrical specification. The multi-stage design ensures that progressive seal degradation in chlorinated or saltwater pool environments does not create an ingress path after a single barrier failure, providing the seal longevity required across an 800-cycle commercial service life.
✅ ⚡ 50A Continuous / 100A Over-Discharge Protection with V0 Fire Rating
The 50A continuous discharge rating sustains the high combined motor load of pool robot drive, brush, and suction systems at full operational power without BMS intervention. The 100A over-discharge current protection provides a hard limit at 2× the continuous rating, ensuring BMS response before any fault condition — stuck brush, blocked impeller, connector fault — can drive destructive current levels through the 4P7S cell array. The V0 fire-rated enclosure material self-extinguishes within 10 seconds of flame source removal and produces no flaming drips, meeting the highest UL 94 flammability classification for equipment operating in occupied pool environments. CC-CV charging at 5A returns a depleted pack to full capacity in approximately 2.6 hours on a compatible charger.
✅ 🔧 Quick-Release Design for Commercial Pool Operation Battery Rotation
The quick-release mounting system allows a depleted battery to be removed and a charged unit installed without tools. For commercial pool facilities running cleaning robots on extended daily schedules, the ability to swap batteries in seconds — rather than waiting for an in-robot recharge cycle — directly increases daily cleaning coverage and reduces robot downtime. The 200 × 80 × 50 mm form factor and 1.6 kg weight are optimized for single-hand handling during battery exchange, and the compact profile fits the battery bay geometry of current-generation cordless pool cleaning robot platforms. For OEM robot manufacturers, voltage, capacity, dimensions, and depth rating are all configurable to match the specific mechanical and electrical requirements of a new platform design.

التعليمات
Q1: What does multi-stage waterproof mean and how deep can this battery operate?
The multi-stage waterproof design uses sequential independent sealing barrier layers rather than a single gasket as the sole ingress defense. Standard production units are IP68 rated to 20 meters — covering the operational depth of the majority of cordless pool cleaning robots. For OEM customers requiring deeper-rated packs for underwater hull cleaning or specialty robotic platforms, depth rating is configurable to 100 meters within the same electrical and mechanical specification. Specify your required depth rating at the time of order inquiry and we will confirm the appropriate sealing configuration.
Q2: What is the difference between the 50A continuous discharge rating and the 100A over-discharge current protection?
The 50A continuous rating is the sustained current the pack is designed to deliver under normal pool robot operating conditions — drive motors, brush systems, and suction combined. The 100A over-discharge current protection is a hard BMS limit that triggers at 2× the continuous rating, designed to respond to fault conditions: a stuck brush motor stalling at locked-rotor current, a blocked impeller, or a connector short that drives abnormal current through the pack. The 100A threshold is high enough that normal operational peak currents do not trigger a false cutoff, but low enough to protect the 4P7S cell array from destructive fault current levels before cell damage occurs.
Q3: What is the minimum order quantity and is OEM/ODM customization available?
Standard wholesale minimum order is 10 units, with tiered pricing at 30, 50, and 100+ units. OEM/ODM customization covers voltage, capacity, cell configuration, depth rating (20m to 100m), enclosure dimensions, connector type, and enclosure markings. OEM minimum is 50 units with a 7–10 working day lead time after sample approval. Engineering samples (1–3 units) are available before volume commitment.
Q4: What does the V0 fire rating mean in practice for pool robot applications?
UL 94 V0 is the highest flammability classification for plastic enclosure materials. A V0-rated material self-extinguishes within 10 seconds when a flame source is removed and produces no flaming drips that could ignite secondary materials. For pool cleaning robots operating in occupied pool environments — residential pools with users present, commercial aquatic centers, hotel pools — V0 enclosure material provides the fire safety margin appropriate for consumer-accessible equipment. It does not replace the BMS protection functions; it provides the enclosure-level fire resistance that complements electrical protection.
Q5: What is the charging procedure and can the battery be charged while the robot is in the pool?
The CC-CV charge mode uses a constant current phase at 5A until the pack reaches 29.5V, then transitions to constant voltage while current tapers to the termination threshold. Full recharge from depleted takes approximately 2.6 hours. The battery must be charged in a dry environment with the charging connector properly mated — not while submerged. Remove the robot from the pool, confirm the charging port seal is intact, connect the charger, and return the robot to operation after the charge cycle completes. Charging temperature range is 0°C to +45°C; do not charge in freezing conditions.
Q6: How should the battery be maintained in chlorinated and saltwater pool environments?
The IP68 multi-stage sealed enclosure provides complete isolation from pool chemistry. The V0 enclosure exterior is resistant to standard pool chlorine concentrations (1–3 ppm free chlorine in residential pools, up to 10 ppm in commercial pools). After each use, rinse the connector face with fresh water and inspect the quick-release latch mechanism for debris. For saltwater pools (2,000–4,000 ppm sodium chloride), specify saltwater-compatible connector materials on OEM orders. For storage exceeding 30 days, discharge to 50–60% charge and store between 10°C and 25°C in a dry environment.
