Ive read a bit about how its not good to either drain the battery to 0 or top off 100%, the sweet spot is between 30% and 80%, is that true like it is on Electric Cars?
Stress no. Yet doubling life means $350-1000 every few years staying in my pocket, products difficult to remediate out of the landfill, and a great mode of transportation is even more sustainable. No stress, just common sense. Its to easy.Best thing is not worry about it. Charge it and use it. It will last a few years then when it dies, rebuild it or buy another. Not worth stressing over.
Buy a battery big enough to charge at 80-90%. You can double the life. No exaggeration. Good science and a fact. Easy to do with a timer and mulitimeter or a charger that will charge at 80-90%. I sold many batteries and have near a dozen. Its a fact. Grin builds an expensive battery, $300 that will pay for itself on your first battery. After 3 years now number 4 my batteries are nearly 100%.
$300 to extend a battery that costs $600 by 100%. Do the math. If my battery will do 800 cycles instead of 400 that means I saved how much? Simple. It means my $900 investment gave me $1200 in value.. The second battery now doubles in value due to doubled cycles. With no additional charger costs. Simple math. For a stable like mine with 8 batteries the payback is huge. Even if you're a one battery and low end owner, the numbers still work.It also means spending a lot of green on this fancy charger day one.
I agree. In three years perhaps the glass electrolyte batteries developed at the University of Texas will be in the market. Such batteries will have three times the energy density as lithium-ion batteries, providing three times the range. They will charge faster and have much longer life cycles. They will be safer, too, free of the dendrites that cause lithium-ion batteries to short-circuit and burst into flames. They might even be able to be charged 100% without any shortening of their lifespan.Spending $300 on another charger or using timer/multimeter is not what most people will do or even want to do. The technology is continuing to evolve and 3-4 years we might not even be discussing this. Go out, enjoy your ebike, charge it when it needs to be charged and don't worry about it.
