"I wanted to let you know I am very pleased with the service you gave & the quality & condition of the solar panels I received from EcoDirect. I will purchase more items in the future from EcoDirect and will be sure to tell others about your fine operation."

"Thanks EcoDirect! My solar system is up and running; waiting for City and San Diego Gas & Electric inspections this week; so far so good!"

My shipment arrived on time, as predicted. Very, very good performance by EcoDirect. What more could you ask for from an online material supplier? Looks like the quantity from Quick Mount is spot on & the rails were bundled safely. EcoDirect will be my recommended source to my friends & neighbors for solar.

Detailed Information

The Discover AES Lithium Iron Battery 42-48-6650 is a single 48 volt battery, with a rated storage capacity of 6,650 watt-hours (138 Amp Hour). Mulitple batteries, up to 10 max, can be tied in parallel for higher capacity battery banks.

The on board Battery Management System (BMS) monitors cell and battery voltage, battery current, temperature, and state of charge. The BMS also performs balancing of the individual cells, micro-managing the charging of each cell individually. The BMS sounds a buzzer when fault limits are reached, reports a fault, and then will shut the battery down after a delay of 120 seconds.

Voltage on Li-Iron batteries holds steady over a wide state of charge, allowing the system to operate at a healthy battery voltage even when the batteries are heavily discharged down to a state of 20% or lower; allowing for a greater amount of usable power in a given package.

The Li-Ion batteries have a narrower temperature operating range, and are best used in environments at typical room temperatures. Backwoods does NOT recommend using this type of battery in a cold environment.

Discover - Lithium Iron Batteries
Discover Advanced Energy (AES) batteries allow for equipment design and functionality improvements and deliver productivity gains through enhanced cycling, charge time and weight reductions in stationary and mobile applications.
