Novi TBB Nemo DM 1260 je najnovejša generacija DC-DC pretvornikov, ki zagotavljajo enostaven prehod s starih svinčenih servisnih baterij na tehnološko izpopolnjene litijeve baterije, ki zagotavljajo visoko kapaciteto in dolgotrajno delovanje.
Litijeve baterije s tehnologijo LiFePO4 postajajo vsakdanjih na plovilih, avtodomih in solarnih sistemih. Zaradi svoje izjemne kapacitete, majhne teže in življenjske dobe tudi preko 15 let, jih vse pogosteje najdemo v plovilih. Ker pa so njihove tehnične lastnosti drugačne od običajnih svinčenih akumulatorjev, moramo pri zamenjavi namestiti DC-DC konverter, ki bo skrbel za pravilno polnjenje litijevih baterij motorjem in preko obstoječega 220 V polnilca. Nova serija polnilcev TBB je enostavna za namestitev in omogoča priklop bluetooth vmesnika, s katerim lahko potek polnjenja baterij spremljate kar z mobilnim telefonom.
Novi pretvornik TBB Nemo DM1260 je idealen za polnjenje litijevih baterij BlueCell z večjo kapaciteto kot so BlueCell 200Ah 12.8V, BlueCell 314Ah 12.8V ali BlueCell 460 Ah 12.8V.

Team Brunel emerged from Stealth Mode overnight as the furthest east in the fleet, and by the 1300 UTC position report on Saturday, Bouwe Bekking’s team was in second place as measured on distance to finish, despite being the northernmost boat in the fleet.
“Yesterday, it was obvious we were falling off the pressure the three leading boats had,” explained skipper Bouwe Bekking. “You can keep following them, but then you know you’re going to keep losing.
“The models we had were telling us to sail the direct course towards the north cape of New Zealand. That’s why we went in Stealth Mode… Fortunately for us, the others kept reaching (out to the west), so we didn’t lose any distance to the mark to these boats. That was the good thing about going into Stealth.”
It’s clear now that Brunel will be pushing the direct route to New Zealand. They will be sailing far fewer miles than the other leading group who are committed to the west, hoping to find more wind to compensate for the additional distance sailed.
“The key goal for us is to get south,” said Scallywag navigator Libby Greenhalgh. “The forecast is still uncertain, but there is definitely pressure to the south and the more we can hook into that the closer we’ll get to New Zealand before the forecast becomes very unclear.
“It’s one of those situations where you kind of have to pick your side and try to win your side. For us, if we can catch AkzoNobel and beat them to win our side, then the worst case scenario is a fourth and best case you win the leg.”
Behind and taking a middle option on the East/West axis is Dongfeng and MAPFRE, the top two boats on the overall leaderboard, now racing in unfamiliar territory at the back of the fleet.
But all hope is not lost, as they claw their way back in terms of distance to the leader, which is now down to just 37 miles.
“The weather forecast keeps changing quite a lot in the files we receive during the day,” said MAPFRE skipper Xabi Fernández. “We have nearly 1000 nautical miles to go so we will keep our hope until the very end.
“The crew is having as much rest as possible and getting ready for any opportunity that may come at the end of the race. Our particular race with Dongfeng keeps being exhausting and we all know it is going to be that way the whole way to Auckland. Let’s see how it finishes. Hopefully we can have Brunel join the battle too.”
Scallywag’s Greenhalgh agrees it could be a fantastic finish: “This is going to be another spic finish with the teams exceptionally close and possibly a full foam up coming in. Will be awesome to watch as fingers crossed we arrive in daylight.”
In Auckland, the Volvo Ocean Race Event Village opened on Saturday. Everything is ready, awaiting the stars of the show.
