[RE-wrenches] Surrette L-16 battereis

[Drake]

For  the time being, we replaced the failed Trojan L-16 E to keep the 
the bank going. We are investigating different options, including the 
Deka batteries. A limiting factor is the footprint of his battery 
bank. It is in a vented enclosure in his living space. To expand the 
footprint would mean major construction. This may be required at some point.
