I sell Kit LEVOREX rev.04 (now also for CARBON and Kenevo).
This is a kit designed for the Specialized Turbo Levo (also adaptable to other e-bikes), consisting of an additional external battery and a device that uses "ideal" diodes (MOSFET technology) to connect this battery in parallel to the original without dissipating energy in heat.
The batteries proposed in the "light" version are of the "water bottle" type, from 224Wh (1250g) or 310Wh (1500g), or to "mini-bag" from 224Wh (about 1000g); this capacity is then added to that of your original battery but, increasing the available autonomy more than expected (from the increase proportional to the total capacity), due to the improved efficiency resulting from the reduction of the current supplied by the original battery.
Also available customized battery sizes.
The kit includes, in addition to the assembly instructions, the battery, the battery charger, pre-wiring and the "ideal" diode device that for the Turbo Levo and Kenevo has been designed to be contained inside the engine compartment.
Kit with "mini-bag" battery: 320 euro + shipping costs
Kit with "water bottle" battery: 380 euro (224Wh) or 480 euro (310Wh) + shipping costs
Possibility to install the kit at + 30 euro
NEW: at + € 85, POSSIBILITY OF SUPPLIED A CABLE "BATTERY - ENGINE" ORIGINAL ALREADY MODIFIED, WITHOUT THEREFORE TO CHANGE ITS OWN; the assembly becomes extremely easy and can be restored to the original very quickly by remounting its original cable.
