Lithium Battery Charging System
It is time for a new battery in my '04 Lance 921. I am looking at an Interstate battery they sell up the road. But through my research into charging systems/problems, I got to thinking about Lithium...

The new EVELF280K cells are rated to 6K+ cycles. Building a pack of Four of these cells will provide longer service than any Lead acid. Combined with 3 or 400+ watts of panels, it's a no brainer.
After doing the requisite research and getting past the initial, kinda-steep learning curve of DIY LFPs and now that I've built one, the cost to energy density ratio is clear.
You can keep watering your cells. I'm done with that ****.
when was the K edition released, at 6K cycles going down to 10V from full is a game changer again. double the life at 100% usage and only 600ish us for a set of 4. I like the way they adresses the bolting also. nice set up.
The LF280K have been around for about a year, I purchased the LF280N the previous version last year.
how has your daily BMS been doing, I went with Overkill solar BMS as the dailys were having some issues at the time, or was that just blowen out of proportion like the internet usaly does?

The first two are working fine except for the SOC I sn’t accurate, I went around and around with Daly but could never get the PC software to work to change their sensitivity, they don’t register a draw below about 3 amps. I am putting together 8 packs so far and have switched to Overkill BMS for the next couple to try them out.
