Nothing easier than to charge a lithium battery :
You connect to a current source continuous maximum current is limited to 0, 3 c (120A for a battery of 400Ah) and the maximum voltage limited at 13, 8V
When the voltage reaches 13, 8V and that the current drops to 0, 025C (10A for a battery of 400Ah), you stop the load.
Once the battery is discharged to 20% SOC, you do it again…
Any battery is potentially dangerous ! Even if the lithium batteries (LiFePo4) are the safest of the lithium batteries (and might even present less risk than the battery lead), they can easily be destroyed and/or be dangerous in certain extreme situations... Read More »
We were ready to go to the Tuamotus, but change of plans at the last minute. Kua and Teiki, our friends of Hakaui, marry in 10 j and the cultural festival of the Marquesas on Tahuata takes place 15 j after... 2 good reasons to extend our stay in the Marquesas!!!
After crisscrossing the islands of the Marquesas Islands in the North to the South since last July, We decide to go back on Tahuata in the Bay of Hapatoni. The atmosphere that reigns among the inhabitants is harmonious, their generosity and their sense of sharing makes this place particularly endearing.
During our first visit to the Marquesas in December 2014, We could not visit the island of Fatu Hiva, the Bay of virgins (Hanavave), because of the swell. We look forward to discover this place( and its inhabitants) reputed to be one of the most beautiful landscape of the Marquesas! Read More »
The mango season begins and the Valley of Hanamenu at Hiva-Oa is covered with mango trees. The night the wild pigs come to eat, but hunters are waiting for them. Josephino kill at least two each night and we show him how to prepare a ham dry...
The Marquesans love it and Nathalie prepares it in no time. Thanking them for all the fruit they give us, We bring to them a cake... and friendship does the rest! Ask all who taste the recipe… Now we drive them to the TAO Blog. Read More »
See performance clearly superior to those of the lead-acid batteries, the lithium battery (LiFePo4) seems the best choice for the boat service batteries. But they are very sensitive to certain parameters that must master before embarking on this adventure. Read More »
