1) http://www.victpower.cn seems to be the cheap a123 suppler. 2) The charger can be reprogrammed, I have never done it. But you can find info on the deltaQ chargers here on this forum and also DIY. 3) I would think one would just ditch the ZERO BMS, I have a newer "MX" bms here and it is now...

Odd I was at zero a week back and saw a stack cells, I asked if those guys have changed to the pouch a123 cells and was told yes.... The other problem with a change in cell type is the dash on the MX. It will pull out the solenoid on signal from the BMS. Havent looked if its active or just...

The drop with a123 will be well under what the e molicel can do. All of the new zero packs are a123.

Here is the PDF for the details http://www.thunder-sky.com/pdf/vip.pdf

I think its a good idea. I feel a huge number of people will be installing micro-grids over the next few years. Not just the above type of devices but going full stand alone solar or micro nat gas turbines.

I would like to add the ATL cells will puff. I have about 50 or so here that have, Id guess 50 out of 500 Ive had problems with. The ATL cells seem to be sealed good its rare to find one not vac intact. When the mfg of the batts that I work on was building packs new from cells I've seen evidence...

All 3g cell access for the kindle is via Amazon servers. Use and abuse the data and you will find your kindles 3g shut off. A call to support tells you your warranty is void and you will need to buy another device.

I deal with ATL branded cells a good amount in laptop batt's I've open and rebuilt over 500+. To me its one of the better mfg's of cells around. I have cells going back to 2003 that still hold a charge good and test at 85%. Even cells that have been sitting at 0.8volts for 2+ years I've been...

Found this news story and have been hunting for detail. Anyone know what kind of capacitors a cruse ship would use? After a complete investigation, the UK's Marine Accident Investigation Branch (MAIB) ruled this week that the event was actually the result of an engine room explosion. In a...

How does it get 5c....cooling and burst to only 5c. "internals are quite different" as in some/all cells will get on-board circuits to take the cell in and out of the pack and or cells behind a master cell. The decay starts from the time the cell is mfg'ed. And can go to 20% depending how it...

check out these cute little guys http://www.youtube.com/watch?v=0Z8dFlVNrY8

Yup ditch the lead and you are good to go. Check how the link10 is connected to make sure it dosnt tap off a group of cells and drain them.

I like the price but bet we dont see that for about 4-5 years. Here's the link http://www.greentechmedia.com/articles/read/flow-batteries-coming-into-homes/ Have not heard much about this batt type. This is darn tempting if these guys can do this at $7500 bucks. hype? scam? spam?

60% efficiency at 1,500watts, 12,000BTU of Natural Gas. Start-up time 25 hours! 36-72 hours of power needed just for cool down if you shut it off. Grid independent not possible. This unit needs to spend allot of time getting to temp. It also needs to off load some of that heat. If you get free...
