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.
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...
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...
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...
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...
