Yup, you read that right. I just ran the first test of a battery pack for my Makita UC4000 electric chainsaw. Well OK here is the description: * Prosine 2000 watt inverter/charger http://www.xantrex.com/web/id/41/p/1/pt/7/product.asp Thats 2000w continuous, 4500w peak power. The unit also has a 3-stage 100amp charger built in. * 2 x 6v-220amp batteries Concorde SunXtender AGM deep cycle, http://www.concordebattery.com/xtender_main.php PVX-2240 * Battery box * 250amp DC breaker/switch * 4/0 cable for connections. * Small furniture dolly so I can move it around the garage. This was put together to allow transporablility setup for easy disassembly so I can take it with me to the neighbor to cut up locally downed tree's. Questions: WHY? Why not? So I could go out and buy two gas powered chainsaws for the same price. 'Cause I wanted to. Also, my SUV is electric Toyota Rav4EV, I have electric lawn mower, I have electric chainsaw, AND I have 5.2kw of solar panels on my house, it's an electric thing. So how well did it work. It will not be until this weekend that I will have a chance to give it a full test. First impression - runs BETTER off of inverter than regular plug. No slowing down motor seems very strong. Also lower noise, no gas, no fumes, no vibration, etc. The inverter has a display of power usage. I was seeing 12v @ 200+amps, and 120 volts @ 20amps. That chainsaw is putting out 3+hp! No wonder it cuts so well, the only real question now is how long the battery lasts. Last year when I was out using OP power I had problem with popping breakers on 15amp circuits. Using this rig I can charge from a low power circuit and run from the battery. The charger can be turned off/on from the remote control panel. By the way DO NOT even dream of running this thing from any regular car starting battery you MUST have the high power deep cycle ones. I had also considered using a Honda EU2000i generator from what little I've seen I donot think that generator could have handled the load, it's continuous load is 1600w and 2000w peak. That chainsaw seems to run about 2000w+ / 750w or about 3+hp. I'll add to this on the weekend when I have more data. I can also do pictures later. -- Brandy PS, I got the inverter refurbished, would not even dream of doing this at list price. Battery box cost more than the inverter/charger.
