Product Description
The Balder Power 36V 12Ah lithium battery is engineered for water rescue robots and autonomous surface vehicles deployed in emergency response operations — applications where battery reliability, fast field exchange, and sustained drive power in submersion-risk environments are mission-critical requirements.
At 36V / 12Ah, this pack stores 432Wh and delivers 50A continuous discharge to sustain 2,000W rescue robot drive motor systems at full operational load. The 250 × 120 × 98 mm form factor weighs 1.6 kg — light enough to minimize the payload impact on rescue robot buoyancy and maneuverability, and compact enough for the battery bays of current-generation water rescue robot platforms. The quick-release mounting design allows a field operator to swap a depleted pack for a charged unit in seconds without tools, maintaining continuous rescue robot deployment during extended incident response operations where recharging time is not available.
The IP68 enclosure is pressure-rated to 30 meters depth, covering the full submersion risk envelope of surface water rescue robots that may be submerged during capsize events, wave action, or recovery from shallow water environments. The Hall switch provides power control through the sealed enclosure without any physical penetration of the housing wall — a magnetic field from an external trigger activates the output circuit, maintaining full IP68 integrity at the switch location across the repeated wet cycling of emergency deployment and recovery. The underwater hot-swap capability allows battery exchange without surfacing the robot, enabling continuous deployment rotation in multi-robot rescue operations.
Internally, the pack uses Samsung 18650 lithium cells — a cell selection providing the energy density, discharge rate capability, and manufacturing consistency required for emergency response equipment where performance must be reliable on first activation regardless of storage duration. For procurement teams evaluating this battery for rescue robot OEM integration, emergency services equipment supply, or research institution fleet deployment, voltage, capacity, depth rating, and enclosure configuration are all available for OEM/ODM customization.

Features & Advantages
✅ 🚨 Quick-Release Design for Rapid Field Battery Exchange in Emergency Operations
The Balder Power 36V 12Ah pack uses a quick-release mounting system allowing a depleted battery to be removed and a charged unit installed in seconds without tools. In water rescue operations, the ability to maintain continuous robot deployment across an extended incident — river search operations, flood response, harbor rescue — depends on minimizing the time a robot spends out of the water for battery exchange. The quick-release design eliminates the fastener removal and alignment steps that slow conventional battery replacement, keeping robot deployment continuity as high as possible during time-critical rescue scenarios. Combined with the underwater hot-swap capability, operators can maintain near-continuous robot operation in multi-unit fleet deployments throughout a rescue operation.
✅ 🌊 IP68 Hall Switch: 30-Meter Waterproof with Zero-Penetration Power Control
The enclosure is IP68 rated to 30 meters depth, providing complete waterproof protection across the submersion scenarios that water rescue robots encounter: capsize events, wave submersion, shallow water recovery operations, and extended operation in heavy rain and spray. The Hall switch activates battery output through the sealed enclosure wall by detecting the magnetic field of an external trigger — no button, lever, or mechanical switch penetrates the housing at the activation point. Unlike conventional mechanical switches where O-ring compression fatigue and corrosion progressively degrade the seal with repeated wet cycling, the Hall switch maintains full IP68 integrity at the activation zone regardless of operational cycle count. This makes it particularly well-suited for emergency response equipment that may sit in storage for extended periods and must perform reliably on first activation when a rescue call comes in.
✅ 🔋 Samsung 18650 Cells: Reliable Performance for Emergency Response Duty Cycles
The cell array uses Samsung 18650 lithium cells providing the energy density and discharge rate consistency required for emergency response applications where the battery must deliver full rated performance on activation after unpredictable storage periods. The 50A continuous discharge rating sustains a 2,000W rescue robot drive motor at full operational thrust — sufficient for counter-current navigation in fast-moving water, towing casualty loads, and sustained high-speed surface travel to reach a rescue target. The 1.6 kg weight minimizes the battery’s contribution to total robot payload, preserving buoyancy and maneuverability characteristics that are critical for precise positioning during rescue operations. Voltage, capacity, and waterproof rating are all configurable for OEM robot platform integration.

FAQ
Q1: What is the actual tested submersion depth and how is the Hall switch sealed at 30 meters?
The pack is IP68 validated to 30 meters depth under sustained hydrostatic pressure loading. The Hall switch activates the output circuit by detecting the magnetic field of an external trigger through the sealed enclosure wall — no physical component penetrates the housing at the switch location, so there is no gasket or O-ring at the activation point to degrade with repeated wet cycling. This is particularly relevant for emergency response equipment that may be stored for extended periods between deployments: a conventional mechanical switch seal can dry out and lose compression during storage, failing on first activation in the field. The Hall switch has no such failure mode.
Q2: How does the quick-release mounting work and what is the typical field swap time?
The quick-release system uses a tool-free latch mechanism that allows the battery to be removed with a single-hand operation. In field testing, a trained operator can complete a battery swap in under 15 seconds. For water rescue robot deployment, this means a robot can be recovered, battery exchanged, and redeployed in under 30 seconds total — maintaining near-continuous coverage during extended rescue operations. The underwater hot-swap capability extends this further: in multi-robot deployments where one robot can be positioned near a tender vessel, battery exchange can be completed without full recovery to the surface.
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, enclosure dimensions, IP rating, Hall switch sensitivity, quick-release mechanism specification, 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 is the expected runtime on a 2,000W water rescue robot drive system?
At full 2,000W drive load (approximately 55A at 36V), runtime is approximately 12–15 minutes continuous. In typical rescue robot operation alternating between full-thrust navigation and reduced-thrust positioning, practical runtime is 20–35 minutes per pack. With two packs in rotation using the quick-release system, continuous robot deployment is achievable throughout extended rescue operations. For longer endurance requirements, the capacity is configurable up to 20Ah or higher within the same enclosure footprint on OEM orders.
Q5: Is this battery suitable for saltwater rescue operations and how should it be maintained after saltwater use?
Yes — the IP68 sealed enclosure provides complete protection in saltwater environments. After saltwater operations, rinse the external connector face and Hall switch activation zone with fresh water. Apply dielectric grease to connector mating surfaces every 30–50 deployment cycles. The Samsung 18650 cells and BMS are fully enclosed with no exposure to the operating environment. For rescue robots deployed in marine environments, inspect the enclosure gasket seating every 200 cycles and confirm no visible deformation before continued use at rated depth.
Q6: Can the voltage and capacity be customized for different rescue robot platforms?
Yes — voltage options include 12V, 24V, 36V, and 48V; capacity can be configured from 5Ah to 30Ah within compatible enclosure geometries. The quick-release mounting interface, Hall switch trigger sensitivity, connector type, and enclosure dimensions are all configurable for OEM robot platform integration. For rescue robot manufacturers integrating this battery into a new platform design, we recommend requesting engineering samples and providing your mechanical interface drawings for fitment confirmation before volume commitment.
