Wow! That's impressive, Bill. As Capn Amel says "Respect de la Batterie"...or something like that.

It is easy to forget that batteries contain a HUGE amount of energy because we usually see it released a little at a time under careful control. Being a bit paranoid about battery condition is a good thing, and Bill R’s description of what to do is a excellent approach.
Just for some round numbers, I put my engineering nerd hat on and sat down to calculate how much energy really is stored in a Amel battery bank. I knew the number was going to be large, but the magnitude surprised me...
420 Amp-hours X 24 Volts = 10,080 Watt-hours
10,080 Watt-hours = 32,000,000 Joules
1 gram of TNT releases about 4000 joules when it explodes.
So one Amel battery bank contains as much energy as (very roughly) 8 kg of TNT!
Of course even a worst case battery scenario can't release all that energy anywhere near fast as detonating TNT, but still….
Respect the battery!
