Yes, it is possible. There are two ways to make the electrical connection: with the 3 x 1.5 cable (to be run outside the chimney up to the speed regulator) in order to extend the first metre attached to the chimney fan.
Or you can make an internal connection to the chimney with our high-temperature resistant cable, which you can purchase separately by selecting the desired quantity in the drop-down menu according to how many meters you need.

Electric fence battery charger
A dedicated electric fence battery charger extends the service life of the 12V sealed lead-acid battery powering a Gemi portable energiser by delivering a controlled charge profile that avoids the overcharging and undercharging conditions responsible for most premature battery failures. Gemi Elettronica supplies chargers matched to the capacity range of batteries used with its 12V energiser models. Gemi battery chargers are available individually and in twin-pack configurations for installations with multiple 12V energisers. Order direct from Gemi Elettronica for factory pricing, UK delivery in 24–48h and pre-sale advice on charger-to-battery matching.
Automatic multi-stage charging
Gemi battery chargers use a multi-stage charging algorithm — bulk charge, absorption and float maintenance — that mirrors the profile recommended by battery manufacturers for maximum cycle life. The charger switches automatically between stages based on battery voltage and current acceptance, and enters a low-current float mode once the battery reaches full charge, maintaining the state of charge without overcharging during prolonged connection.
Preventing battery failure in fence applications
Electric fence batteries are typically charged infrequently and may remain connected to a charger for extended periods between grazing seasons. An unmanaged charger operating at constant voltage will cause electrolyte loss and plate sulphation over time, reducing capacity with each cycle. The automatic float management in Gemi chargers eliminates both failure modes, maintaining the battery at peak capacity regardless of how long it remains connected between uses.
Compatible with all Gemi 12V batteries
Gemi battery chargers are sized and programmed for the 7Ah to 38Ah sealed lead-acid batteries supplied as part of the Gemi electric fence range. They are also compatible with equivalent-capacity batteries from other manufacturers, provided the battery chemistry is sealed lead-acid or absorbent glass mat.
