considering a 80AH agm is over 450.00 bucks up here, and have been for over 4 yers now, I wouldnt say there was much of a cost risk. two of thoes in my camper would give me 160AH total for about 1K including taxes.. for 900 I did 300AH of LFP, droped from 130 to 49lbs, and was able to put it in the original battery space for the old camper freeing up my outside storage space which was taken up by the GC2's

Battery pricing varies but around here the 100AH AGM I got five years ago for $230 (Can) is now $330 and a T105 has gone up from about $155 to $255.

So 300AH of AGMs is now $990 before tax and core fee. Meanwhile a drop-in LFP price (not for sure typical as they vary) is about $1,500 for a 150AH so two would be $3,000

Somehow by rolling your own you got 300AH of LFP for $900 so that is quite a saving.

ya bare cells I got for 150 each plus shipping. happened to catch a sale. don't forget though, to get as much life as you can out of thoes AGM batteryies you need double the 300AH I got with the LFP cells and still won't get as much life. so that makes the AGM much more expensive, and even compared to the off the shelf ones, they are a lot closer in price. but there are several places in canada you can buy 100AH prebuilt ones for around 500 each now so that would be 1500 for 300AH capacity. the prebuilts are slowly coming down in price but I am worried whats going to happen now that electric cars are starting to switch to LFP. might get more expensive due to demand or may get cheeper due to increased production. only time will tell.
