Lithium batteries for Electric APUs

I've been saying this for years that the battery APU units need to be Lithium with a battery box designed to hold them and be insulated.

The weight advantage of lifepo4 VS AGM is huge.
The BCMs used on most of these provide proper protection and battery health.
Finally Carrier has woke up and offered a lithium battery APU that uses Lifepo4 batteries

 

That carrier lithium apu is $17000!!!
No thanks. You can build your own lithium system for less than half that.

 

I'll add that there is a newer lead acid battery technology known as lead - carbon which is seemingly making a nearly indestructible battery. These might be usable without modifications to the charging system too.

 

How about a quarter of the price.

 

Look what I came across today ….

 

Why pay double the price when you can get the same battery on Amazon ... from the same chinese source. Chins is on of the brands. They even have models with low temp heating. Bluetooth battery monitoring, etc

Best made on the market is probably SOK. No cool features other than low temp shutoff.
