Headway cells

[rickystyx]

Anyone got any headway cells they no longer want?
Not looking to spend much
I've got a little tractor thing for my manual chair and I've got my 30Ah add on pack that never gets used so I thought I would use it for the tractor (which also won't get used much) but it would be good to have a slightly bigger pack in it.
I only want it so I can get something on and off my boat as a powerchair is too heavy to do that and this will work happily on the towpath to get me back to civilization and the car when necessary.

eBay? https://www.ebay.co.uk/itm/Excellent-HE ... %7Ciid%3A1

Seller might be keen to sell separately. They've been listed for weeks.

Thanks but I'd really like to have the same 15Ah cells so I can match them up properly - if I don't find any I'll stick a couple of small lead bricks in instead but I know several people made up the 30Ah packs and may have them doing nothing so it was worth an ask

These go very fast . They just came back in stock today. They will be gone in a day or two.

But they are only 8Ah.
I have some tiny tesla 21700 cells here that are 5Ah. Two in my RC transmitter.

We need greater capacity than that like 40 or 50 for an addon pack, or 200 for a full pack, so the high C rate is not important to us. Headways are now a decade old. Things moved on. And many sizes of prismatic (rectangular) cells with way higher energy density and low cost appeared. Thats how we can make light small 50Ah addons, or 200Ah chair packs. So I would avoid using headways - as good as they are/were today.
