Taking the LiFep04 Leap

[dktool]

With my lead acid bank getting long in the tooth but still usable I thought it was time to start playing with the lifepo4's.
For a first go I wanted one with bluetooth to see what's really going on, or at least what the bms is reporting, and at least 200 ah and 200 bms and didn't want to absorb more $ into this experiment than necessary.

I found some 300ah with 250A bms that were attractive but no bluetooth, almost went there and would let a shunt monitor talk to me but again, really wanted to see inside the battery.

I opted for this one at $562 delivered, 200ah 200A bms, bluetooth and a touch pad one the battery.
It also claims low temp protection which in my environment was not going to be a dealbreaker if it didn't have it.

I am in the middle of this same process. See my thread "Going Lithium". I like that this has the battery monitor built in. If you go through my thread, you will see that you will need to check your converter, you solar controller (if you have solar) and think about a dc to dc charger to protect your TV from a discharged lithium battery that will try to draw more amperage from the TV if left to its own devices

I received the battery and also purchased a 35amp charger with the Vevor brand name, it is a company that has it's hand in a lot of products for very reasonable price.
Example is I bought a spare propeller for my 25' boat for about half the typical cost.
This charger was $65 I bought it for general use outside of the MH, I have a 2 bank 40 amp smart charger in the MH that will handle charging the Lifepo.

The battery came at exactly 50% charged which is what is recommended for long term storage.
I charged it and will play with loading and discharging to see where it shuts off.
The bluetooth works good too.

Vevor appears to be a direct from China internet store. I've had bad experiences with those companies, never again.
I requested to return an item, the selling company told me to use the shipping label they emailed me, then pay for shipping back to China.

I only buy those brands when it's Amazon Prime.
