We don't typically use them. Only thing I add to all my banks is small balancer

 

I just use a balancer on mine, a bms is mostly unnecessary in most use cases

 

thanks guys for your feedback/experiences.

battery hookup is selling some LTO cells, their customer service recommended using an LTO BMS, so i was checking if this was a thing /common.
There are some that exist on ali express from Daly, which is reputable, purportedly.

i found this LTO BMS project too, guy made his own custom bms fun project!

DIYBMS for Lithium titanate battery cells (LTO)

Hope this will help This is my YouTube playlist of the LTO build 30 boards Total: A$101.77

The whole point of a BMS is to control the whole output of the battery.
If you are going LTO, you probably want a lot of power out of it, then you'd have to buy at least the 500A BMS, and it might still hinder you in power output.
If you don't need that much power then it might work well.
A Heltec balancer is all that is needed as long as you balance the bank before usage.

 

I personally don't need a ton a of power, I just want stout stable voltage source for the vehicle/system. I think the BMS's allow higher pulse currents for shorter durations also? like a 100A BMS may allow 300A for shorter durations. the 100A current rating, for example is usually approx. 30 second or 60 second limitation, roughly? you can go higher current for shorter durations.
