PTO-2590 Battery Pack – BB-2590 Compatible Rugged Power Solution

The PTO-2590 rechargeable battery pack serves as a high-performance, drop-in alternative to the BB-2590 battery. Engineered for demanding field operations, it delivers consistent, dependable power for portable mission-critical equipment where reliability cannot be compromised.

Main Technical Parameters

• Nominal Voltage: 28.8V
• Rated Capacity: 9.9Ah
• Cycle Life: ≥500 cycles at 100% DOD, with minimum 80% capacity retention under standard 25℃ test conditions
• Protection System: Integrated smart BMS (Battery Management System)
• Supported Functions: Overcharge protection, Overdischarge protection, Short-circuit protection
• Cell Type: High-density lithium-ion cells
• Form Factor: Direct mechanical and connector compatibility with BB-2590

Core Advantages

1. Verified Long Cycle Performance Every battery pack is subjected to continuous charge-discharge aging and cycle life testing on our automated test racks, the same equipment shown in our factory photos. Under standard laboratory conditions, the pack can complete a minimum of 500 full 100% depth-of-discharge cycles while retaining at least 80% of its original capacity. Longer cycle life reduces battery replacement frequency, cuts operational downtime and lowers total ownership cost for end users deployed in field missions. 

2. Built-in Smart BMS Safety Control
 The embedded battery management system monitors individual cell voltage, current and temperature in real time during charge and discharge. It automatically triggers protection against overcharging, over-discharging, over-current and short circuits. This active cell balancing and protection mechanism prevents permanent cell damage under abnormal operating conditions and greatly improves overall battery reliability and service life.

3. Direct BB-2590 Form Factor Compatibility Designed as a plug-and-play replacement for BB-2590 batteries. Identical outer dimensions, mounting layout and connector interface allow seamless installation. No mechanical modification or firmware adjustment is required for your existing portable devices, simplifying product upgrade and spare part stocking.

4. Rugged Construction for Harsh Field Environments The battery pack adopts reinforced housing structure, optimized for tough outdoor, mobile and vibration-heavy field environments. It maintains stable power output during continuous mobile operations, delivering steady power even under variable temperature conditions. This rugged design makes it well suited for mission hardware that cannot afford unexpected power failure.

Application Areas

• Signal Jammers
• EOD (Explosive Ordnance Disposal) devices
• Man-pack portable radios
• Field unmanned robots
• Portable surveillance systems
• Other portable tactical and industrial mission-critical equipment

Strict Quality Control Process

We implement multi-stage quality inspection covering the full manufacturing workflow:

1. Raw CellsIncoming Inspection: Every batch of lithium cells undergoes capacity, internal resistance and voltage sorting. Poorly matched cells are eliminated before assembly.
2. PCBA & Wiring Harness Inspection: BMS board and cable assembly are tested for connection integrity and insulation performance.
3. Aging & Cycle Life Verification: Finished packs go through continuous charge and discharge aging testing to validate stability and cycle performance.
4. Final Functional & Visual Inspection: Check appearance, connector integrity, full charge/discharge function and protection circuit before packaging and shipment.

The PTO-2590 battery pack combines BB-2590 drop-in compatibility, reliable cycle performance and comprehensive BMS safety protection, making it a practical, cost-effective power upgrade for portable field equipment. Backed by rigorous factory aging and cycle testing, this battery delivers stable power for jammer, EOD, man-pack radio and robotic systems in harsh working conditions. Whether you need prototype samples or mass production, our team stands ready to provide tailored power solutions and professional technical support to ensure your mission-critical devices operate safely and consistently.
