    DIY LiFePO4 Starter Battery?

    Very cool. Keep me in the loop! Under what brand will this be manufactured? Antigravity Batteries already has a Lithium starter battery on the the marker with the “run flat” protection feature so my may want to run a patent search before proceeding.

    Help me choose the right BMS for these systems

    Ok! Thank you! This is very helpful. So it is dependent on both on the capacity of the inverter as well as the charging amps? How do I find out what my charging amp capacity will be? Is that based on my load calculation?

    Help me choose the right BMS for these systems

    For my 4S - 272Ah - 12v array for example, will a 120Ah continuous charge/discharge BMS like this one work? For my 8S2P - 544Ah - 24v array, will this one be sufficient? Is it based on the calculated load or the Amperage rating of the battery or...? Thanks oh mighty hive mind!

    Help me choose the right BMS for these systems

    Ok, thanks! I wasn't sure of best practices for the larger bank. Can all 16 cells be a series connection? Should they be? Which way is preferable?

    BMS for DIY motorcycle starter battery.

    Yes I am familiar with them and I have talked to them also. It’s the only battery of its kind on the US market. Counting DCS from Australia, that makes two brands who make automotive starter lithium batteries. Is that it? Any other brands out there?

    Has anyone purchased LiFePO4 batteries from Wintonic?

    Yeah I was hoping to hear from someone who had already been brave enough to order something like this. :) Are there other Chinese brands out there that makes a battery with similar spec? Some manufacturers have free shipping so I was hoping to find a battery similar to this that would ship for...

    BMS for DIY motorcycle starter battery.

    According to the Vice President of Relion they only make starter batteries for outboard fishing motors and other accessory items. Not for cars, RV’s, etc.
