36V 2X RAPTOR KIT – LiFePO4 128Ah 4.8kWh

The 36V 2X RAPTOR KIT is a dual-battery LiFePO4 system delivering 128Ah capacity (4.8kWh total energy), designed for applications requiring sustained high-current output. Its 36V configuration supports mid-voltage electric vehicles like utility carts or marine equipment, while LiFePO4 chemistry ensures 3,000–5,000 cycles at 80% depth of discharge. The “2X” architecture enables parallel/series flexibility, with integrated BMS protecting against overvoltage (±0.5% tolerance) and thermal runaway. Charging occurs via 42V cut-off (3.6V per cell), balancing efficiency with longevity. Maximizing the Lifespan of Golf Cart Batteries

What distinguishes the 2X RAPTOR architecture?

Modular 36V LiFePO4 packs allow parallel doubling of capacity (128Ah→256Ah) or series boosting to 72V. Proprietary busbars minimize resistance losses (<0.2mΩ), while IP67-rated connectors ensure weatherproof operation. Pro Tip: Parallel setups require matched internal resistance (±5%) to prevent uneven aging.

Unlike single-battery systems, the 2X RAPTOR uses master-slave BMS communication to synchronize charge/discharge. Each 128Ah module contains 12 LiFePO4 cells (3.2V nominal) in 12S configuration. When paralleled, the combined 256Ah system delivers 9.6kWh—ideal for solar storage or extended EV runtime. For example, a dual-pack setup could power a 1,500W trolling motor for 6+ hours. But what if one module fails? The redundancy design lets the functional pack operate at 50% load while triggering BMS alerts. Critical: Always use identical firmware versions across modules to avoid communication errors.

⚠️ Critical: Never mix 2X RAPTOR kits with lead-acid batteries—voltage sag differences cause BMS lockouts.

How does 128Ah capacity impact real-world performance?

The 128Ah LiFePO4 cells provide 20% higher energy density than standard 100Ah EV packs. At 25°C, they maintain 95% capacity after 2,000 cycles (0.5C discharge), dropping to 80% at -10°C. Pro Tip: Pre-heat batteries below 0°C using <5% SOC to prevent lithium plating.

A 36V 128Ah pack delivers 4.6kW for 1 hour continuously, sufficient for 48V golf cart conversions (derated to 80% load). Compared to lead-acid, it saves 60% weight—28kg vs 75kg for equivalent capacity. But how does this translate to range? In a 500kg utility vehicle drawing 30A average, expect 4–5 hours runtime (≈40km). Tables below contrast key metrics:

Redway Battery Expert Insight

The 36V 2X RAPTOR KIT exemplifies LiFePO4’s adaptability for modular energy systems. Redway’s balanced cell matching (±15mV) ensures stable 128Ah performance across parallel configurations, while CAN-enabled BMS supports real-time SOC tracking. Optimized for 0.2C–1C discharge rates, it bridges the gap between compact EVs and industrial backup power needs.

FAQs

Can I series two 36V kits for 72V operation?

Yes, but only with a 72V-rated BMS upgrade. Stock configurations limit series connections to prevent MOSFET breakdown above 60V.

What’s the minimum charging current?

10A (0.08C) for cell longevity. Below 5A, balancing circuits may not activate, causing ±3% capacity drift over 50 cycles.
