 | Too Smart by half rating: 4
Works well, but sometimes the smarts are not smart enough. Some times it charges a full or nearly full battery at too high an amperage and you know it shouldn't. You turn if off then back on, and it acts properly. Sometimes it won't charge a battery in bad shape, but a simple & stupid charger will. I'm on my second. The first would go into equilizing mode by itself, though the engineers at Xantrex couldn't see how that was possible! All in all it's a nice device and a worthwhile purchase.

Efficient, powerfull, well made rating: 5
I have been testing battery chargers and batteries for charging efficiency as a byproduct of marine wind turbine testing I am doing. Of the 5 different chargers I tested, this was by far the most efficient.
It is also very powerful; for just a little more than a standard 15 amp charger, you get 40 amps. The 3 stage charging program significantly speeds charging of large capacity batteries.
I bought 1, used it for several months, and was so impressed, I bought a 2nd one to boost the charging capacity of a very large batter bank.
It is ideal for use as a charger for boat battery banks, either cruising sailboat or for bass boat type trolling motor battery banks.
