Rotating Batteries and Burning Bushes [RE-wrenches]

I have noticed a swelling at the terminals on the first and last Trojan L-16 in 48 volt battery banks. In some cases I have had to replace battery #1 and #8 and #1 and #4 in a 24 volt bank. A German engineer who works with diesel engines and trace invertors on large systems recommends rotating batteries. All my batteries use 40 cable from all the + to - on the batteries. I asked Richard Perez about the swelling phenomenon at MREA last week. HE said that the first and last battery with large draws from an inverter have a capcitator type of effect and he suggests rotating batteries if invertors are used. He said that larger the cables - the worse the effect. One come systems in the past I have rotated #1 and #8 with #4 and #5.

NOTE: All batteries had plenty of water that had the swelling problem. And feedback on rotating batteries? Richard said he would write an article on this.

The MREA Fair was great - it was nice to meat other old gray beards who have been rolling the sun up the hill for so many years. It got me juiced up in the age of deadly global burning BUSHES and other Texas homegrown dopes transplanted to Florida.

PS: One water miser cap's benefit is that you can check the water level without removing the cap. Hydrocaps sometime turn to charcoal dust when equalized. Hydrocaps are sandwiched carbon cylinders with a platinum screen.
