Hi Michael,
Looking at the details you provided for the EVO battery, I suspect these are
of similar construction and chemistry to that of the Shorai batteries, they
are certainly aimed at the same market.
I you look at my most recent post you will see comparison performance
graphs.
As far as fusing and terminal insulation is concerned, I cannot
overemphasise the importance of placing a fuse holder with the shortest
possible lead to the positive terminal (Positive is by convention, it can
actually be on the negative terminal) and then securely covering both
terminals with hard plastic insulation material. From experience a 5 amp
fuse is more than sufficient for most glider installations and in our club
we are using the automotive blade style of fuse holder.

New to the group so please excuse any ignorance demonstrated but I have been
looking at the EVO2 as a battery.
It has a balanced charging port which I am led to believe can up to double
the life expectancy of the battery.
Claimed Pb equivalence is 15 A/H @ 768g.
No low voltage and/or high current cutout board installed, but a nearby fuse
on some well covered posts should do the trick perhaps?
There are a couple of Australian web sites that sell and shipped within
Australia.

Agreed; something like this would be better

14AH - twice that of a normal SLA glider battery - and less than half the
weight @ 662g

Hi Ian
>From a safety point of view this is much better than what the Boeing

is using.
However, I would never put a battery like that in a glider unless it is
securely placed
in a much more impact resistant enclosure.
Kind regards

About $87 and notice a new Arcus M was fitted at factory with something
similar. This is NOT what B787 is using.
