So be far i have now finished the biggest job of my project.
To support the i3 battery it required a ali frame and i have added suspension mounts to reduce vibration or impact on the battery.

With the battery mount and tray mounted in the rib. I was the tasked with re-assembling the battery with its 8 x cell modules.

With the final cable connections connected i was finally able to but the adapted lid over the battery. With it all now sealed down with a neoprene gasket, i can now get on with switching the system on!!

Next install to follow shortly

The big switch on, propellor turns, antifoul and awaiting a sunny opportunity to get this project tested.



So, i am super pleased, as today i energised the system.
It went very well and as throughout this project, the big unknown was, if the second hand BMW i3 60ah battery would connect and properly communicate with the Torqeedo deep blue system. It now has demonstated that this works.
With the prop now turning, i need a sunny day to launch her an run through some on water tests.

I will be posting all performance details when i have them as well as a video to ensure transparency.

Whilst i await for this sunny day, iíve slipped the rib off the trailer to remove all the old antifoul. ( which i will not need as the rib will always be recovered home)

Happy days!!!!

Hello! Very carefully and with interest I follow your project. I'm really looking forward to your boat running tests.
There is a small technical question: how the ventilation of the battery compartment is provided. After all, if you just close the lid, the condensate will do its dirty business in just a couple of seasons?
Thank you.

Afternoon Ziby FD,

I have installed two 12v engine space blowers, which will provide alot of circulation around the battery, but this is only if i get an issue with over temp. The i3 batteries temp sweet spot is 20deg c. If after the test i get issues i will try the blowers. Worst case i have to run refrigerant through the batteries exchanger ( as in the car).
Let see
Thanks for your interest
