There is no motor in the circuit.
These are just encased Li accumulators in magnets
charging up big electrolytic caps or
lead acid batteries(accumulators).
Surely you could also power a motor from it, but better first
charge up a few supercaps with it.
He said in the German patent, that he has removed the security
circuit from the cell phone Li batteries he has used.
So he uses the pure Li cells.
As there are 2 different Li cell type on the market,
Li-Ion and Li-Polymer maybe one type is working better ?
I guess also Li-Polymer is a bit safer...

Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the batteryâ€™s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.
Charging Lithium-ion Polymer
Charging Li-ion polymer, also referred as Li-polymer, is very similar to a regular lithium-ion battery and no changes in algorithm are necessary. Most users wonâ€™t even know if their battery is Li-ion or Li-polymer. The word â€œpolymerâ€ has been used as promotional hype and does not reflect special attributes other than to know that the battery is built in a different way to a standard Li-ion.
Most polymer batteries are based on a hybrid architecture that is a cross between Li-ion and Li-polymer. There are many variations within the polymer family, and the true dry polymer battery for the consumer market is still years away. Also know as the â€œplastic battery,â€ this system was first announced in the early 2000 but was never able to attain the conductivity needed for most applications at ambient temperatures.
Simple Guidelines for Charging Lithium-based Batteries
* A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
* Charge at a moderate temperature. Do not charge below freezing.
* Lithium-ion does not need to be fully charged; a partial charge is better.
* Chargers use different methods for â€œreadyâ€ indication. The light signal may not always indicate a full charge.
* Discontinue using charger and/or battery if the battery gets excessively warm.
* Before prolonged storage, apply some charge to bring the pack to about half charge.
* Over-discharged batteries can be â€œboostedâ€ to life again. Discard pack if the voltage does not rise to a normal level within a minute while on boost.
