Hello Everyone. I'm new to the forum, but I've been visiting for years. Thanks to everyone who has been contributing to this resource.
I'm fairly novice when it comes to battery storage, and even more so with LFP batteries. I have an existing 24v setup with Magnum Energy components and 1200ah of AGM batteries. My batteries are aging, and I think it's time for an upgrade. Given my novice nature, I'm deliberating between off the shelf batteries or a DIY kit. I've priced out both and it seems like the DIY option is substantially better. I'm not trying to do this on the cheap and I generally believe in buying the right thing once. That said, it's hard to ignore the savings. Currently I'm deliberating between two options: 1) 5x EG4 LiFePOWER4 24V V2 Battery (USD $5,745) 2) 4x DIY batteries, possibly built into Seplos 25.6V 280Ah DIY cases. (4x350=$1400, 32x77=$2464, Total $3,864). It would appear to me that the second option provides ~10% more capacity for ~2k less. I suppose I have 3 questions:
1) Would you recommend either option?
2) Assuming I'm reasonably competent, follow the instructions, read the forum and watch the videos - how long should it take to get the DIY system working?
3) Am I missing something, such as extra costs or considerations? Of note, I can and will set a custom charging profile for the new batteries.
Thanks for reading and I appreciate any advice you can offer.
