Battleborn posted a comparison video, AGM vs GC2 vs Lithium and to their dismay found that the GC2 was the most cost efficient. They did their best to hide those results but they did not delete them.
Lithium on makes cost sense if you keep them more than many years, which few people do. How many sets of GC2 can you buy for the price of one set of Lithium
GC2 is the most cost efevtive if you buy sams club cheep ones and your only talking about one purchase. if you buy quality GC2 batteries your up in the ball park for LFP when you look at usable AH, for exmple a GC2 rolls surrette (one of the best 6V deep cycles you can get) is 450 each, so 900 bucks to get 265AH of 12V so based on life thats 132.5AH usable for 800-1000 cycles. for 900 cdn I can buy 300AH 12V LFP in a DIY format (including buying a quality BMS and the stuff to build it) . far cheeper not even taking longjevity into account as over twice the usable AH or I could buy two 100AH comercial sold 100AH batteries, which still have more AH and life than the GC2's. if I go with the cheepest option up here that would be costco at 150 each for 208 AH so 104 usable for max life which will most likly be about 600-800 cycles. do to get 200 usable AH you need 4 so thats 600 bucks which is only 300 bucks off the set up above. and I havent even talked about the 3-4000 cycles you get from the Li to justify the long term cost comparison. the price has dropped enough that you can do Li cheeper than quality alternaitives. I never understood why people always have to find the cheepst brand they can and compare it to a quality then nd say well I can buy two or three of thoes for this price... what about the work uying new ones , changing them out, inconveniance when they **** the bed while your camping (which is normaly when you find the issue) and so on. do you do that with tools , I can buy 10 of these wrenches for the price of that one...... theres usaly a reason for stuff like that...
