Planing on replacement my victron gell battery's ( after 5 years ) to lithium. There are so many brands ( no Temu ?? ) and all claim wanders. Is anyone have good info on the brand for lithium batteries ? Some claim many different cycles life. I have no shore power staying on the hook and wonder if charging new batteries with DC DC charger ( new are about 30% charged only ), is enough by running engine will be sufficient.
