Battle Born batteries

[snoozer]

Long time lurker making his first post. I'm curious if anyone has any experience with Battle Born LFP batteries. The time has come for replacement of my lead acid bank, and they look promising. I am somewhat leery, based on their price point being considerably less than other brands (SimpliPhi), based on the old maxim "you get what you pay for". Thoughts?

Do you have a link to the specs on these batteries ?

Not the specs themselves, with a little digging I found the voltage and current limits for the onboard BMS. Otherwise, battlebornbatteries.com.

here are  a  few links over on NAWS, who apparently is a dealer now...

You can get Calb 100 AH cells for 128 each ( without shipping ) so 4 to make 12v pack  would be $512  .
That leaves about $400 to pay for  BMS and shipping.

Guess it depends what you want to do with them. . Those Battle Born say you can only series them to 24v and they only have 1 C discharge where the Calb have 2 C discharge capability .  You can charge the Calb at 1 C - not sure if you can do that with the Battle batteries  - I don't see any charge current specs so must be much lower than 1 C

Thanks, Larry. I will look into these.

Call a few of those EV car parts places listed on the Calb USA dealer website and ask their advice - they have a experience with different types of Lithium cells.
There are also some new technology lead acid gel type cells on the market that are not supposed to sulfate up ( lead crystal) that you could consider also. Depends on your needs. With lead acid usually you size to only use 20 to 30% of capacity for longest life span.
Also depends on temperature you will keep the batteries at as to which battery types will be best suited.
