Title: battery box using water bottle holes?
Post by: Akis76 on September 09, 2009, 09:56:58 PM: is there any battery box that can be installed into the water bottle holes of our bikes?
I mean something like this

PowaByke's 36V 6Ah lithium-ion power pack disguised as a water bottle:

If there was a great demand for them, I'm sure GM would consider marketing them.

I expect it will be a box style rather than a bottle style in order to accommodate a reasonable battery capacity.

Post by: Perbear on September 12, 2009, 09:56:18 AM: I built an experimental battery pack using two 19V 4900mAh LiPo packs in series with a simple balancer board, all wrapped up in a shrink-fit sleeve. The weight is 1,22 kg and gives about half the range compared to my 10Ah 36V GM pack that weights around 5,2 kg. The LiPo (lithium-polymer) pack fits in a slightly expanded bottle holder but it is not a safe battery pack, missing temperature sensors, waterproofing and mechanical protection. All this is required to have a safe pack.

Many houses and garages have, and will, catch fire due to ebike battery packs not being built safe enough. Check out http://www.extraenergy.org (http://www.extraenergy.org) where some examples can be found. Also call your local fire department and ask if they know about any fires started by lithium batteries...

Hi. I made a box with aluminium sheets, and it is bolted to the water bottles holes ( I have 2 pairs) and also I have another attachment to the frame of the bike at the top right angle corner. http://goldenmotor.com/SMF/index.php?topic=437.0
