BigBattery 36V EAGLE2 LiFePO4 Battery with Heater and Comms

The 36 V EAGLE2 is a drop-in lithium battery module designed to upgrade existing 36 V platforms. It fits in GC2/T-105 tray installations and serves golf carts, neighborhood electric vehicles (NEVs), industrial equipment, and other 36 V applications, delivering longer life, higher power and improved reliability compared with legacy packs.

Key specifications

• System voltage: 36 V (nominal 38.4 V)
• Capacity: 1.63 kWh (40 Ah) nominal
• Max continuous discharge: 80 A (~3,072 W)
• Peak discharge: 200 A for 3 seconds
• Operating temperature: –20 °C (–4 °F) to 60 °C (140 °F)
• Weight: ~17.2 kg (38 lb)
• Protection: IP67 / NEMA-6
• Form factor and expansion: GC2/T-105 tray compatible; supports up to ten parallel connections

Safety features, communications and reliability

• High-quality LiFePO4 chemistry for improved cycle life, thermal stability and safety versus lead-acid or generic lithium packs
• Integrated heater enables self-heating for reliable cold-weather performance
• CANbus communications interface for smarter monitoring, controller integration and fleet-management readiness

Installation and maintenance

Designed as a direct upgrade for legacy 36 V systems, the EAGLE2 fits most existing GC2/T-105 trays and replaces lead-acid packs without major controller changes. Its lighter weight and stable voltage under load reduce maintenance needs compared with traditional packs. For scalability, additional units can be paralleled (up to ten) to increase capacity while preserving footprint.

Warranty and support

The BigBattery 36V EAGLE2 is backed by a 12-year warranty, underscoring its long-term durability and service life in demanding 36 V applications.

Ideal applications and benefits

• Golf carts and NEVs transitioning from lead-acid to a robust lithium solution
• Industrial equipment and forklifts operating on 36 V systems
• Marine or RV 36 V house-power and light electric-vehicle platforms

Key benefits include improved usable energy, faster charging, reduced maintenance, cold-weather readiness, and system intelligence through CANbus integration—delivering reliable, scalable power for real-world 36 V deployments.

BigBattery 36V EAGLE2 1.63 kWh LiFePO4 Battery with Heater and Comms

Modernise your 36 V platform with a drop-in lithium battery kit that’s designed to deliver longer life, higher power and improved reliability in a compact GC2/T-105 form-factor tray. Ideal for golf carts, NEVs, industrial equipment, and other 36 V applications.

Why This Battery Stands Out

• Direct upgrade for legacy 36 V systems – This unit fits in most existing tray-mount setups (GC2/T-105 style) and replaces lead-acid packs without major controller changes.

• High-quality LiFePO₄ chemistry – The use of Tier-1 LiFePO₄ cells delivers longer cycle life, improved thermal stability and increased safety compared to traditional lead-acid or generic lithium packs.

• Heater and communications built-in – Integrated self-heating ensures optimal performance in cold conditions, while the CANbus communications interface enables smarter monitoring and system integration.

• Robust performance specs:

  • System voltage: 36 V (nominal 38.4 V)

  • Capacity: 1.63 kWh (40 Ah) nominal

  • Max continuous discharge: 80 A (~3,072 W)

  • Peak discharge: 200 A for 3 seconds

  • Operating temperature range down to –20 °C (–4 °F) and up to 60 °C (140 °F)

• Durable build & protection – Weighs approx. 17.2 kg (38 lb), with IP67 / NEMA-6 protection rating to safeguard against dust and immersion.

• Expandable & future-proof – Supports up to ten (10) parallel connections for higher capacity systems.

• Solid warranty & longevity – Backed by a 12-year warranty, designed to live in service for over a decade.

Key Benefits for Your Application

• Improved range & efficiency – Replacing older lead-acid packs with this lightweight lithium solution boosts usable energy and reduces weight.

• Faster charging & less maintenance – LiFePO₄ requires less upkeep, has better charge acceptance and holds voltage more steadily under load.

• Cold weather ready – The built-in heater supports optimal performance in lower ambient temperatures, helping avoid reduced power or early cut-offs.

• System intelligence – CANbus comms allow the battery to integrate with controllers, display systems or fleet-management tools.

• Upgradable platform – Start with one unit and scale by paralleling more to build higher capacity banks without changing footprint.

Intended Applications

• Golf carts and neighborhood electric vehicles (NEVs) originally using 36 V lead-acid packs.

• Industrial equipment & forklifts where 36 V battery replacements are common.

• Marine or RV house-power systems sized at 36 V.

• Light electric vehicles or custom e-mobility platforms seeking a robust lithium upgrade.

If you’re looking to upgrade a 36 V system with a reliable, long-life lithium battery that’s easy to install and built for real-world use, the BigBattery 36 V EAGLE2 LiFePO₄ kit offers a compelling mix of performance, durability and value. With high discharge capability, cold-weather readiness, communications support and a trusted warranty, it’s engineered for next-level reliability.
