Hi Jeremy,
I have a lot of LiFePo4 battery systems out there on the Outback platform and
we ran into that issue also. The main issue with the Low SOC alarm is the
blinking red light that tends to unsettle clients. The trigger for the Low SOC
alert is adjustable though, and it’s pretty easy to

My personal opinion is that you should not buy any lithium battery that does
not provide adequate protection for all modes of operation.
Freezing does not damage the battery; charging a frozen battery may damage it
quickly. Trickle charging the battery is not the solution.
There are two
I doubt you will do any good with trickle charging at cold temps. LFP is
too efficient and there is litlle self heating, so this will not work.
Probably need to use LA or roll the dice. An expensive mistake if you
lose. Even heating pads need a fossile fuel source in cold country with
LFP
Folks,
If I have a charger that does not have low battery charge cut-off, I can
get in trouble if I have a frozen pack and apply a charging voltage.
But, if I start with a pack that is above freezing and keep a trickle
charge on it, can I keep that pack safe from freezing and damage?

Hi All,
As Larry said, when a lithium BMS disconnects, this causes a "load
dump" just like disconnecting a lead-acid battery. Well-designed
chargers (solar or otherwise) should be able to handle this without
damage, though a failing or poorly-designed lithium battery may cause
this to happen

There was some off board chatter about this subject but I think it is useful to

If a Li battery EMS or BMS detects a fault condition, it can cause an open

William,
This is one reason I choose to avoid the black box approach to Li-ion
batteries for our customers. There are several companies offering enclosed
battery/controls like the OES. Their approach does not match well to the
off-grid and mobile markets that I serve.
Since most LFP
One thing that could possibly be done is to have a smaller lead acid
battery in parallel with the LiFePo bank
so the LiFePo contains most of the energy storage, but the LA can
supply the surges and low impedance
source voltage.

On 9/18/2014 8:53 AM, Starlight Solar Power Systems
boB,
When charging a LFP battery, the charge terminates when absorb voltage is
reached unless you have an enormous charger in which case you will need to
terminate based on AH returned. You would also need to isolate the LA battery
to finish charging it. Plus, LA needs higher voltages than
Yes, well of course there are these details.
If the LFP surge is a limitation, but not its amount of overall
energy storage, then you may have to add a very large amount of LFP
storage to overcome that which
could be overkill and cost a lot of extra $.
It's all a compromise.
boB

Truth is there is likely more than enough capacity in the LFP battery the
customer has but the manufacturer built a limit into the “box. The limit of
our battery is set to 10C for 30 seconds. WAY more than any inverter can draw
with even a small bank.

On Sep 18, 2014, at 12:26 PM,
Oh, OK then. I thought that somebody had noticed a voltage drop when
surging.
When people ask me if they can use LFP or other Lithium chemistry
batteries, I tell them yes because
when they buy a LFP battery system, (or one of their Lithium Ion
relatives) it has all the protection

boB,
IMPORTANT: If you ever plan to make a Li-ion control I/O, do it with CAN bus.
The whole industry is there. Our GBS product has CAN bus on the CPU to control

potential. It would be easy for my CPU to tell the
Yeah, CAN bus is used (was designed mainly) for automobiles and I bet EVs
