Now that the theoretical bases were exposed, It is time to practice. Read More »
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 »

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 »
It all started in April 2015 during a walk on the banks of the new marina in Papeete. Read More »
Coming from the unibody I had kept the habit of putting, on Tao, a hoist used boom by wind. It was struck between the central cleat and a bridge to the 2/3 the back of the boom... until the day when the cleat pulled out... and a buddy has folded its boom with the same technical!!! As you learn by mistakes and especially what they cost us, this to triggered a reflection on the adaptation of this technique for a catamaran... which does not cash the oversales and other gitant errors! So here is 6 months I'm sailing downwind with a "Bungee" boom...
