Apollo Neptune LA-C5.1: 5.12kWh LiFePO4 Energy Storage System
Engineered for Pakistan's power outages and severe summer cooling demands. The Apollo Neptune LA-C5.1 delivers true 5.12kWh automotive-grade lithium iron phosphate storage, seamless plug-and-play communication with Apollo, Deye, Voltronic, and Inverex inverters, and eliminates the toxic fumes, acid maintenance, and short lifespans of outdated tubular batteries.
Automotive-Grade LiFePO4 Chemistry & Precision BMS Architecture
Watch the deconstructed animation revealing the high-density prismatic cell matrix, active 1.5A balance circuitry, multi-protocol CANbus handshake, and multi-layer thermal barrier engineered for 55°C Pakistan ambient conditions.
Four Pillars of Lithium Energy Storage
How Apollo Neptune LA-C5.1 sets the standard for residential energy storage in Pakistan: automotive prismatic cell longevity, intelligent cloud-sync BMS, uninterrupted nighttime AC cooling, and multi-layer thermal defense.
Automotive Grade-A Prismatic Cells (6,000+ Cycles)
Built with Tier-1 automotive lithium iron phosphate (LiFePO4) prismatic cells featuring laser-welded solid nickel-plated busbars. Unlike traditional tubular lead-acid batteries that degrade within 18–24 months in Pakistani heat, Neptune provides over 15 years of uninterrupted daily deep-cycle service.
Intelligent Multi-Protocol Smart BMS with Auto-Handshake
The brain of the Neptune LA-C5.1 is an advanced 16S automotive microcontroller BMS with active 1.5A cell balancing. It establishes dual-bus CAN / RS485 communication protocols with leading solar inverters, ensuring precise real-time state-of-charge synchronization and fault prevention.
SOC, SOH, cell millivolts reported to inverter every 100ms.
Sub-millisecond over-current and over-temp hardware shutoff.
Heavy-Duty 100A Continuous Nighttime Inverter AC Discharge
Unlike weak lithium packs that throttle when an air conditioner compressor kicks in, the Neptune LA-C5.1 is engineered for 100A continuous discharge (5,120W output). Power your 1.5 Ton Inverter AC, refrigerator, deep freezer, and full home lighting through oppressive load-shedding nights with zero voltage dip.
Multi-Layer Thermal Protection & Hardware Circuit Breaker
Pakistan's summer ambient temperatures regularly surpass 45°C–50°C. Apollo Neptune LA-C5.1 is encased in heavy 2mm aviation cold-rolled steel with flame-retardant ceramic insulation, dual internal temperature probes, and an integrated heavy-duty DC isolator circuit breaker.
