Mecer 12V 200Ah Lithium ion battery – with 2nd LiFe PO4 chemistry – SOL-B-L-M200

Original price was: R8999,00.Current price is: R7299,00.

A 2nd LiFe Battery is not second-hand. A 2nd LiFe LiFe battery has been repurposed and the cells have had their life extended by being applied to less strenuous operating conditions. These 2nd LiFe batteries are often time repurposed after use in electric vehicles. This makes them less expensive than comparable alternatives. They are also environmentally responsible, reducing electronic waste and repurposing important materials.

What is a 2nd LiFe Battery?

In short, these are EV batteries repurposed for residential use.

Automotive-grade (EV) cells are manufactured specifically for use in the very harsh environment of a motor vehicle. This includes being mobile, subjected to vibrations continuously, high temperatures and to high charge and discharge currents in the effort to optimize charge time vs distance vs speed.

Stationary storage applications change this high throughput requirement and optimize the requirement to provide a lower throughput over a longer period of time, significantly enhancing the life expectancy of the once automotive battery.

Battery Runtime Formula

Why is this beneficial to us?

Typically a backup storage battery is designed to provide power throughout the night, around 10 hours or more, or at worst for at least the 4 hours of load shedding we all love and thank Eskom for daily. The 2nd LiFe battery is repurposed and configured to this backup workload and is then typically running at 1/10th of its maximum designed output which lends itself to an extended life, and an optimal cost per kWh.

Effectively, an automotive-grade cell running at less than 1/10th of its design potential can obviously be expected to last longer than initially planned.

Secondly, an automotive-grade 2nd LiFe Lithium Iron Phosphate battery, used in a stationary storage application like a Trolly Inverter, is subjected to charge and discharge currents that are significantly lower than its design capability. This reduced stress translates into a non-linear improvement in terms of cycle life, easily providing the same lifespan as a new battery specifically designed to provide stationary storage only, at a much-reduced cost.

We highly encourage you to read this thread on the PowerForum to understand this battery better.

  • In serial connection, the BMS can be used for 4 batteries (up to 48 volts)
  • If you need parallel application you have to connect the inverters in parallel – not batteries.
  • Please charge the battery within 7 days when the battery is in low voltage.

Note: Do not use this battery with a modified sine wave inverter, especially the cheap Mecer 720watt, etc inverters, we recommended you use it with the 12V 1kW Pure Sine Wave Inverter
