Engineering & Integration

Integration & Operational Boundary Conditions

Charger Voltage Compatibility Note: This is a 2S 7.4V lithium-ion pack. Charging equipment MUST provide an 8.40V cutoff CC/CV charging profile. Never attempt charging with 4.2V 1S chargers or unregulated power supplies.

BMS Current Rating: Integrated PCM supports 15A continuous current and cuts off overcurrent at > 25A within 10ms to protect cell chemistry from external shorts or motor stall conditions.

OEM Customization: Available in side-by-side (19×37×68mm) or end-to-end stick (Ø18.5×132mm) configurations with custom wire harnesses, balance charging taps (JST-XH 3-pin), and private label branding.

⚙ Engineering FAQ & B2B Procurement Specifications

What is the turnaround time for custom battery pack prototypes and mass production for GEB 18650 7.4V 1500mAh 10C High-Rate Li-ion Battery Pack (2S1P Configuration)?
Custom prototype development typically requires 7 to 10 business days after CAD drawing approval and technical specification freeze. Commercial mass production turnaround is typically 15 to 20 business days. Standard OEM minimum order quantities (MOQ) start at 50 to 100 units depending on cell chemistry, custom mold tooling, and casing complexity.
Does GEB provide UN38.3 test summaries, MSDS, and Class 9 dangerous goods export compliance?
Yes. General Electronics Technology (GEB) provides complete first-party compliance verification for all industrial battery packs, including UN38.3 test reports, 1.2m drop test appraisal certificates, MSDS/SDS sheets, and certified dangerous goods packaging compliant with IATA air transport and IMDG maritime shipping regulations.
What smart telemetry protocols and BMS protection features are supported?
Our custom smart BMS architectures support industry-standard communication protocols including UAVCAN, CANbus 2.0B, SMBus, UART, and RS485. Integrated hardware protections include multi-tier over-voltage, over-discharge, continuous over-current, short-circuit, and dual-channel NTC thermal cutoff safeties with active cell balancing options.
What are the recommended continuous and peak burst discharge margins?
To maximize lifecycle endurance and electrochemical stability, we recommend designing with a 15% to 20% continuous discharge headroom margin under typical operating loads. Peak burst discharge ratings should strictly adhere to specified duration windows (typically ≤10 seconds) while ensuring pack operating temperatures remain below 65°C.
