Revov is making waves in the news because our 2nd LiFe batteries are more than a formidable solution, they also contribute to a cleaner, greener planet.

Revov prides itself in offering solutions utilising Second Life (2nd LiFe) Lithium Iron Phosphate batteries. – 2nd LiFe batteries are not brand new but have been repurposed from their original function and design, which was to power plug-in electric vehicles (EV’s). The key differential attributes between our repurposed 2nd LiFe batteries and other new variants are as follows:

Batteries only qualify for 2nd LiFe status once they have done their time in a full electric vehicle and passed the test of time and performance. That time is 5 to 6 years inside a commercial taxi, bus, or truck, being used during the day and getting a full re-charge at night. In this scenario the battery loses about 0.011% of its initial capacity daily, resulting in a loss of about a 20% of the original installed capacity after the 1,800 cycles. At this point the battery is not producing sufficient energy for the vehicle to maintain its original specified performance, and it is therefore necessary to be replaced with a new battery. This also means that they are slightly bigger than brand new Lithium Iron Phosphate batteries, as they started LiFe as a larger capacity battery than they are now.

Our 2nd LiFe batteries are automotive grade, which means that the quality of cell within the battery is better than storage grade cells. Our automotive grade battery was originally designed for the electric vehicle, and therefore needs to better withstand harsher conditions such as extreme vibration, temperatures, and higher charge and discharge rates. This means that our repurposed 2nd LiFe batteries will offer similar and most often BETTER performance to new LiFe storage grade batteries , but at a better price. We offer the same warranty for both our LiFe and 2nd LiFe batteries in our Revov range because we are confident in the performance history of our 2nd LiFe cells and able to accurately predict their future performance – the warranty is for 3500 cycles or 10 years at a cycle a day. This is the minimum performance we expect from our batteries, and we know they will last even longer, for about 4000 – 5000 cycles. Remember a cycle is one full charge and one full discharge.

Our 2nd LiFe batteries puts our carbon footprint at a very much lower number than what a new LFP storage battery is labelled at. Our 2nd LiFe batteries are cherry picked from the bundle of discarded EV batteries, once they are no longer capable of powering electric vehicles – they are repurposed, carefully tested, and rebalanced, and repacked for domestic and light commercial energy storage usage. This means that we are not putting extra pressure on global commodities and resources (lithium) – and by re-using, reducing and repurposing our batteries, we are being kinder to the environment, in that we are saving batteries from being dumped into landfills.

Our 2nd LiFe Systems and solutions are always designed using 16-cell configurations whereas many affordable new Lithium Iron Phosphate battery systems use 48V 15 Cell configurations. This results in significantly higher usable capacity from the 16-cell system, and provides far superior performance at higher continuous current and voltage discharges. In fact, in certain conditions performance at 1C can be 3 to 4 times better than a 15-cell design.

2nd LiFe batteries

The pricing difference between our 2nd LiFe automotive grade batteries compared to brand new LiFe storage grade batteries is about 35% less. The pricing of our 2nd LiFe batteries, per usable kWh (kilo Watt hour), compared to the traditional lead acid battery solution is very similar. Lead acid batteries only have about a 50% usable capacity, whereas our depth of discharge is 100%, that’s why it is cheaper upfront to install lead acid, but lead acid batteries do not deliver the same amount of kWh’s and lead acid batteries have a life span of less than 3 years.. if you are lucky. If you compare this to our 2nd LiFe ‘s life span of a minimum of 10 years, the difference is obvious and that is why, to compare like for like technology over a 10-year time frame, 2nd LiFe is significantly cheaper. It is important to also note that lead acid technology is not as safe as Lithium Iron Phosphate batteries and requires extensive maintenance.

The same comparison can be made with a traditional generator, where upfront costs for the generator are much lower, however over 7 years, our 2nd LiFe batteries become the cheaper option when you add up the generator service and fuel costs. There is also a simple comparison in a cleaner greener option in 2nd LiFe, in that generators are noisy, pollute the air and can be a fire hazard.

An average household needs 10kWh (kilowatt hours) for its critical loads. The critical load describes the plug point, tv, Wi-Fi and lights electrical requirement over an Eskom outage. 10kw hour battery or batteries (we have different sizes) will stack into a similar size as a countertop washing machine. It is important to note that the critical load does not include geysers and stoves. The DB board in your home will be split up accordingly, and when main power source is disrupted, the critical load will be powered by the batteries. If the requirement is to go completely off grid and generate power solely from wind and solar energy, then the requirement for battery storage will be much higher.

Our Revov MD, Lance Dickerson, was the guest speaker for Steven Ambrose’s Tech Talk podcast for 101.9 ChaiFM last week. Lance spoke about how he and co-founder, Felix von Bormann, couldn’t help but notice that the trajectory for power supply across our African continent was pointing downwards in 2016, so the entrepreneurial pair decided to bring a solution to our deteriorating power system, by sourcing clean and cost effective technology, called Lithium Iron Phosphate batteries, or for short – LiFePo4 – for the scientists amongst us.
