ETX900-TSO-REVX Overview

Part: ETX900-TSO-REVx — EarthX, Inc.

Type: Lithium Iron Phosphate (LiFePO4) Starting Battery

Description: 13.2 V, 15.6 Ah LiFePO4 starting battery with integrated Battery Management System (BMS) and thermal runaway containment, designed as a maintenance-free replacement for 12-volt lead-acid or lithium starter batteries in 14 CFR part 23 Aircraft.

Operating Conditions:

Supply voltage: 13.9–14.6 V (Standard Charge Voltage)
Operating temperature: -30 °C to +60 °C (short term +65 °C)
Max altitude: 25,000 Ft
Max charge current: 80 A (from aircraft charging system)

Absolute Maximum Ratings:

Max charge voltage: 16 V (from aircraft charging system)
Max continuous discharge current: 31 A
Max short term environmental temperature (on ground): 85 °C (30 minutes)
Max storage temperature: +70 °C

Key Specs:

Nominal Voltage: 13.2 V
Capacity (1C, 1hour rate at 23 °C): 15.6 Ah
Peak Power (Ipp, 23/-18 °C): 800 / 390 amps
Rated Power (Ipr, 23/-18 °C): 600 / 365 amps
Self-Discharge Rate: <3%/month @25°C
Life (Charge cycles): 4000 cycles @1C discharge rate, 25 °C (20% depth of discharge)
Weight: 5.4 lb
Dimensions: 166mm (L) x 79mm (W) x 168mm (H)

Features:

Integrated Battery Management System (BMS) with cell balancing and over-charge protection.
Over-discharge protection (disconnects below 5% charge, <11.5V).
Excessive cranking protection (limits high current use to 10-30 seconds in any 60-second period).
High temperature protection.
Short-circuit protection (>1000 Amps).
Redundant main electronic battery disconnect components.
Thermal runaway containment system with vent tubes.
Charge voltage protection greater than 60V (blocks charging current above 16V).
Built-in LED indicator and discrete output for fault monitoring (fast flashing for high temp, slow flashing for improper state of charge/cell problem, solid for BMS hardware failure).
IP 66 environmental rating (resistance to water intrusion).

Applications:

14 CFR part 23 Aircraft (as a maintenance-free replacement for 12-volt lead-acid or lithium starter batteries).

Package:

6.5in (L) x 3.1in (W) x 6.6in (H) (166mm x 79mm x 168mm)
