SOK 206AH battery installation

[hbn7hj]

I replaced two 100AH Battleborn batteries with two SOK 206AH batteries. The footprint is not the same and they are a little taller but I had the room.

The Battleborns arrived fully charged 6 years ago. The SOK batteries arrived depleted. It takes a long time to charge 412AH from a generator. SOK would like the charge rate to be 40 amps per battery. I charged at 90 amps total for almost four hours by generator to a charged voltage of 14.3 volts.

The Battleborn weight was 28lbs each. The SOK spec is 48lbs each.

I paralleled them with two remaining healthy 100AH Battle born batteries. Each bank has it’s own battery monitor so I will let you know how that works. If it does not work I can separate them but I expect it to work. I’m expecting a total charge rate of 150 amps. Will let you know what it turns out to be when I get back on the road in July.

The second battery compartment cannot handle two SOK 206AH batteries.

The next job is to install the Velit high altitude furnace. I’ll test it at 10,000 ft in August. The Webasto works so very well below 5000ft I hate to take it out. It won’t last a week at 10,000ft.
