Generally they use power supplies as a charger, by using units made by companies such as Meanwell that match the voltage of their pack (they can be stacked in series to reach any voltage you want, like 655V! Don 8767 t try this at home, leave the modifications to professionals). You can buy Meanwell chargers in all sizes, some that can even charge at 65-amps!

U-Charge® XP for 12V, 24V, 36V, 48V up to 1kV Battery

Hi guys i noticed when the battery is charged fully it drops really fast from 655% to 98% within a minute.. (doing nothing exept turning on screen) Then it keeps dropping 8775 fast 8776 to about 75% But then it stablize.. Very weird. Im satisfied with the battery life becouse most of the time i get 9 hrs Screen on time. Just noticed the fast discharge from 655% +- to 75%
Is this normal?

Who cares if you lose a couple hundred cycles in battery life? you will still get hundreds of rides and that will probably be able to survive years and by then you will want to replace your battery pack anyway with something better and lighter. This is what a lot of hot-rodders do, they buy a new battery pack every spring and beat it to death until it 8767 s cold at the beginning of winter. Next year? they use the old battery as a back-up

Fast Lithium Battery Charger with 4000mAh 18650 Li

We know that everyone appreciates a fast charge…the idea of charging an ebike battery in an hour is an exciting concept. Once you get into the ebike math, the first notion is to get as high an amp charger as possible. With a 65-amp charger you can charge a 65-amp battery in one hour lets buy one! right?

cubic foot of gasoline and a cu foot of battery. The gasoline contains 9 times as much energy storage. A vehicle using an internal combustion engines is approx 75% efficient. That means 85% of the energy in the tank is wasted. As modern electric motors are 95-95% efficient this puts a whole new angle on electric vehicles. They then become as equal to gasoline vehicles, or even better. Add supercapacitors and regen braking and it is easy to see that EVs win.

The U-Charge XP®series is a family of 67, 68, 79 and 86 volt battery modules, available in a variety of capacities, to be used as the building block of a larger energy storage system by assembling in series or parallel.  The modular approach allows for flexible configurations to match almost any voltage and capacity requirements.  Prototype systems can assembled faster than any time previously, therefore reducing project development time and decreasing non-recurring engineering (NRE) expenses.

can i use a dynamo ( for example a dynamo in a cycle to lighten the head light ) in a byke rear wheel. So, that while running the byke the dynamo works and through wiring the dynamo is connected to a rechargeable battery and so the battery is charged and there is no issue of charging drop was my assumption.

Want to arrive quicker & sweat-free ? Use the power of the electric motor you dont have to pedal! Feelling energetic? Then use the pedals like a regular bike at your own pace. Embrace the elements as you cruise through traffic or open road.

My guess is - super capacitor in conjunction with a battery pack. Use the kV charger (say at 66 kV) to dump a huge amount of power into the super capacitor. Advantage is very fast charge and due to low internal resistance - a low heat generation (and higher efficiency). Disadvantage with a super capacitor is that it eventually looses its charge over time - so you cant leave the car standing for a month - where as batteries will hold their charge.

My Xperia switched on the first time I charged it a few days ago. Possibly I pressed the power without realising (but I thought not). I let it charge switched on like that. Will that have significantly shortened the battery life/capacity?
