If your interested in getting an electric RC car then you likely have a handful of concerns concerning what you can expect from them. That is how I treated the LiFePO4 battieries: I would attach the pack to a 1-amp, regulated 14.two volt power provide for 12-18 hours and then disconnect it and then location it on the shelf, possibly topping it off briefly just prior to working with it. The Lead-Acid batteries, on the other hand, are left connected to a 13.six volt power supply and allowed to sit there all of the time when not getting utilized.
This observation spawned some additional testing, so I place the LiFePO4 packs back on my battery tester I was further distressed to note that these that had originally tested out as obtaining 5.eight-6 amp hour capacity have been now, at the extremely most, in the 1.five-2 amp-hour range when the significantly older SLAs have been nevertheless in the 5.+ amp-hour range.
When I applauded them for taking the lead and acting at a time when other folks were still speaking about EV’s, I was also essential of their selection to exclude a sophisticated thermal battery management program which would assist retain a consistent range throughout varying ambient temperatures as nicely as enable extend the battery’s life.
What it implies to you: The Leaf’s most recent battery warranty is excellent news no matter whether you happen to be seeking new or applied, and even if you currently have one. The auto had more than 25,000 miles on it and had been charged more than 500 occasions by then. That the i3’s battery is easily replaceable is excellent – everyone likes to be able to upgrade.
Under the new warranty, Nissan will repair or replace a Leaf’s battery within 5 years or 60,000 miles if it loses a lot more than 30 % of its charge capacity. I have been super excited to see BMW’s carbon fiber EV, but the solution delivered is kind of a disappointment to me. Not only is the 22KWh battery vastly insufficient, the quirky styling is a definite put off. When the battery temperature exceeds 105 degrees there is definite cell harm and capacity loss. Most fast electric RC cars are constructed with standard street tires which are smaller and use much less rubber.
