Default Manual links for Shorai, Ballistic and EarthX at your finger tips

Just thought I would put some links in here so you can easily review what the manufacturer's manuals are putting out there for technical data. We are working with Bob Nuckolls among other professionals to provide the information that is geared toward aircraft as well as power sports so you can make an educated choice in which battery is best for you.

This is for Shorai: http://shoraipower.com/installation-guides

This is for Ballistic's: they don't have a manual that I could find after searching their website, this is the most technical piece of data they have: http://www.ballisticparts.com/tech/charging.php

This is for EarthX: http://earthxmotorsports.com/wp-cont...l_111017_G.pdf

We also have on the Experimental aircraft page, a direct comparison of the Odyssey battery and the EarthX battery so you can see for yourself the differences and what would be the best fit for your use. Sometimes we are better, and sometimes we are not, depending on the model and we list them all so you know what you are gaining or losing. Here is that link: http://earthxmotorsports.com/product...ntal-aircraft/

And I do realize we are a competitor of Shorai, but I can't help but point out they specifically point out in their warranty that use in aircraft is not covered.
Here's that link: http://shoraipower.com/Customer-Service.html

And this is a total plug for our batteries, I apologize in advance, but we are only patent pending technology battery in this market that has over discharge, over charge and cell balancing built into our battery. You do not need a special charger in order to balance the charge/discharge of the cells and this also ensures that while your charging system is charging the battery, it is doing so evenly. And if you read ALL of our competitor's warranties, if you over discharge or over charge their battery it is not covered. Other than cost, the other down fall of a lithium battery is they are much less tolerant to being over discharged or overcharged than a lead acid and doing it one time, you can kill the battery. This type of protection and safety built into our batteries was not an option in our opinion, but a requirement.

That's great info Steve!

I'd love to see other LiFePo batteries tested. Maybe we could convince the other manufactures to send you comparable (36ah) batteries for a good comparison between vendors. :-)

EarthX
Aerolithium
Aerovoltz
Antigravity
Ballistic
etc.

I dont understand the EarthX discharge curves from their manual (see link in their previous post). What are "C rates"? The format of the discharge curve posted by Steve in the first post on this thread is more intuitive and gives me the info I want to know. Would like to see a few more like this at lower and higher amps.

"C" in this case stands for Capacity. For example, if a battery is 10AH then a 1C discharge rate is 10 amps. 1C is always nominally 1 hour to full discharge, 2C a half-hour, and so forth.
