Design and execution of a waterproof battery box for 4 280Ah cells, BMS and thermostat and heating pad under the cells are included. Fuse is on top of the perspex cover for easy access. Any comments are welcome.
Now it is waiting for the battery cells.
it is a 38 foot sailing catamaran with two outboards
the outboards might help charging, there is otherwise 400W peak solar on the boat. The question is whether thereis a riskk either to batteries or outboard charging sytems in the setup since there is no additional srter battery.
I am...
Id di some more checking and experimenting on it. The output of the outboards is perfectly suitable for charging the Lifepos (it is a simple charging coil anyway) and it will charge with 10 A per outboard. The solar is setup that the lifepos are normally only charged to 50% that there is plenty...
yes, two lifepos in parallel as one bank, the lifepos hold the voltage and in case they switch off the small AGMs take over. Simpler to fit than a surge protector which needs to be very close to the alternator coil.
I plant to use the lifepo house battery (2 x 12 V 280 Ah in parallel,( https://diysolarforum.com/threads/waterproof-case-for-4-280ah-eve-or-lishen-cells.17740/ ) ) in combination with a 10 hp Yamaha high thrust outboard, for charging the battery and for starting the outboard. Is there any...
Hi Michael,
I have my lifepos known in operation this season with the 2x 20Ah AGMs in parallel and this is working extremely well (no extra starting batteries). Motoring for two days in a row and the batteries never switched off. I also never got them above 13.6 V as well. Since I set the...
I need to make to make it waterproof because the batteries are stored on my cat in boxes on deck which can be subject to water, spray and the environment. They are going as a replacement to the AGMs. I am also curious about any heat generation, the BMS is supposed to shut off when too hot, but...
