So, it's not necessarily garbage and you could possibly use it for another 4000 cycles or more. 319 cdn? really? did you click on the link? if you did you wouldn't be asking ;) but yes really. i did and it appears to be 319 usd!1.4KViews0likes0CommentsRe: Lithium Battery Upgrade

Instead, do you have room for a larger battery or for a second battery? If not you should still do OK with a single lead-acid or AGM battery. First step would be to do an energy audit. For most of us the big energy hog is running a furnace in cold weather. Otherwise you should be able to boondock for days with a single battery. Refrigerator controls and your CO/propane detector should use very little electricity. Same for the water pump. For many older RVs, incandescent lighting used a lot of power. If that is your issue, consider replacing all of the lighting with LEDs. New LED fixtures are inexpensive or you might be able to replace just the bulbs. some good points, we do need to run our furnace, our trips are usually early/mid fall season in eastern canada, heat is a must! interior lighting is being replaced with LED fixtures. we tried LED bulbs but the lighting was terrible!559Views0likes0CommentsRe: Lithium Battery Upgrade
a hilarious response for sure! all i wanted was a better battery system that would allow dry camping for more than one night at a time. i also realise that charging my trailer battery while driving takes forever through the 7 pin connector, that will be another upgrade to come general conclusion so far? lifeso4 is the way to go so now to choose one and a suitable charger.348Views0likes0CommentsRe: Lithium Battery Upgrade
good to know about the storage state of charge, thx. -10 C is the coldest it gets here in SW ontario! boon docking at -37 C is not in my future! i see ads for lifeso4 batteries all over my facebook feed now of course. so i'm looking for a trusted well known supplier349Views0likes0CommentsRe: Lithium Battery Upgrade
thanks for the replies. charging when cold would not be an issue, we have always removed the battery from the trailer and stored it in my heated garage with a trickle charger. the additional usable capacity is the biggest bonus plus it doesn't need to sit on the a frame, i would mount it inside somewhere and lighter is always a bonus!353Views0likes0CommentsLithium Battery Upgrade
i need a new battery for our 26ft tt, the old lead/acid rv/marine battery is virtually dead after 10 years of service. is it worthwhile to upgrade to a 100 Ah li battery and the necessary new charger? we do boondock occasionally and probably would do more with a better battery capacity. the old lead/acid battery was rarely adequete for more than one night boondocking running the usual lights, fridge and water heater controls.7KViews0likes42Comments
