so my replacement cell should be here today, but now I am faced with another disision which I am going to go to some of the other people that have LifePO4 batteries they have build them selves for their opinion.
JBD BMS (also sold rebranded as Overkill) are a good BMS. I have been happy with the one I have in my other battery but now there is Jk on the scene.
This is the one I have, it is no longer available, but I bought two when I got my original one.
JBD 150 ampthis is the one I am thinking of buying a couple of and replacing what I am using now.

Plus, the reviews on JK BMS have been amazing and the app is set up much nicer.
so, for those that have built their own batteries, would you go with an external 2-amp active balancer if you were building a new battery, or would you go with an active one built into the BMS
