I've just seen the video of Das24680 and seen that you use kJ as the unit for the batteries, but W for power consumtion of turrets and lights.
Most people can't really guess how long the batteries will supply a turret when fully loaded.
To get a better comparabillity how about using Wh instead of kJ for the batteries? (3600kj = 1kWh = 1000Wh)
So... Batteries have 26000kJ => around 7222Wh => It can support 7222 W for the time of 1 hour...
(I know, I know,.. it's not really importent, but it is easier to guess the supply-time when the unit is similiar than to look up the conversion Joule <=> Watt and it's something that catched my eye

)
