I was looking at BMS solutions for my 24 cell 20 AH GBS Elite Power Solutions pack here, http://www.all-battery.com/protectivepcbsforlifepo4.aspx They sell several versions but the 12 cell 20 AH is out of stock. I was wondering if I could use 6 of the 4 cell 20 ah version in my 24 cell pack...

I use emachineshop.com free software to design my 2D parts. It has bend modeling and 3D preview. You can print the drawing out 1:1 on an inkjet or laser printer and then spray glue the back side and stick it to your sheet metal. Then use a straight edge and a scribe to etch the cut lines into...

I am not sure who made the cells. I heard TS changed names anyway. The cells are LiFeP04 and the TS cells were a different chemistry I believe. Do you have a part number for protection boards? Paul

Based on the input so far I may add a 6th battery and get a 36 volt charger. Its a shame I cant use the golf cart charger since it retails for over $400. I got it for free brand new with the rest of the parts so I will sell it here or on eBay and buy the 36 volt Lifep04 from elite. Paul

Thanks for the comments. It's been alot of fun building it since I get to use all my shop equipment. I do 2-3 big projects a year and I build alot of my own equipment. Paul

I just received 5, 20ah 12 volt packs from Elite Power Solutions that I ordered last week. I did not buy the charger they sell or the balancers. The total charged voltage should be 14.4 X 5 = 72 Volts. I am building a custom frame motorcycle based on the "Honda Solo 50" as my goal. I...

Here is a link to the full specs sheet. Have a look and let me know what you think. Even at a slightly lower Ah rate I think $90 each is a good deal. http://www.shoraipower.com/t-battery-specs.aspx Paul

A review of these packs, http://www.batterystuff.com/knowledge-base/index.php?action=article&id=185

Here is another pack @ $109.95 but its 6V 18 Ah so I would need 8. That would be like $880 :shock: http://www.advmachines.com/product_p/lfx18l2-bs06.htm Here is a $159.95 12 V 14 Ah pack, its a Japanese pack with a 2 year warranty...

I was searching for battery packs and I cam e across these. The are designed for high performance-race motorcycles as a light weight alternative to lead acid batteries. http://www.solomotoparts.com/product.php?productid=43444&cat=539&page=1 You could wire them in series parallel to get higher...

I purchased 4 X 12 Volt 7 Ah SLA batteries from my local surplus discount electronics place ($10 each :) )and I wired them in a series for a 50 volt pack. I was wondering what the final charged voltage of the pack should be so I can verify it has a full charge? Thanks, Paul

I think the way to go with these is to plan on buying 2 and run them in parallel. That way you would not put too much stress on one pack. It would also give you a failsafe in case one pack failed you could keep going. I read several reviews for the bikes they sell and it looks like most...
