How far do you get on that? It must be a 10s 1p pack? Are you pulling 15 A from that?

You can pull enough to climb a small hill but not for long. On the flat, you can go up to 5-6 miles with that battery. In the previous post, I meant the Bosch battery adapter, not the Bosch battery.

Ok good
What are these Bosch battery packs designed for? Lawn mowers?
There are quite a few alternatives to Bosch in terms of 36V lawn mowers. I assume you've looked at other brands?
Yes, I did. There are dewalt, makita etc the Chinese company I contacted has similar adapters for other batteries. it would be much better to make my old mold for the downtube on the long run.

I had noticed that there are a number of adapters that allow you to use brand X batteries on brand Y power tools.
Is there one of those adapters that accepts the Bosch 36V batteries that could be hacked to be used as a holder for an eBike ?
Its the sort of thing you just assume; that someone somewhere makes and sells a battery holder for those Bosch batteries, but I cant find one.
I note that ARCC in Cambridge sell a conversion kit for the Bosch batteries;

You could even print a double socket, so you could have the option of having two batteries fitted at once.
I am concerned though about drawing so much current from such a small pack. I can't see it having a very long life, subjected to 15A draw and then recharged in 1 hr at a C1 rate.

Would be for me, PCBs and stuff I dont have a problem with, but never done any 3D printing.
It's a lot easier than you might think. I've just finished a repackaging job for an old Silverfish battery. 3D printing was fine, the hard part was integrating all the fittings in such a way to make it practical and safe. It's the biggest 3D print job I've done so far. When I get the time I'll post a report on it.
The batteries in the 6Ahr pack do have a 10A rated charge I beleive, so should be OK for 15A.
As for routinely doing a 1hr charge, you would think that is going to 'quickly' reduce battery life, but then if you have a holder, easy enough to use your own charger.
6Ah is getting a bit more sensible, a lot of e-scooters have a 7.5 Ah pack. But 2.5 Ah, or even a 1.3? Good point, you could 3D print your own charger housing and charge at more reasonable rates.
With a project like this, you could easily take your pack into a coffee shop or whatever and plug into any modern USB port and recharge opportunistically.
Mind you, £158 for a 4Ah pack seems a bit steep, when you can get a 15 Ah Silverfish for about £180.

It's free from the point of view of the customer. He already has the battery in his lawnmower
I can just imagine it..."I think I'll cut the lawn...oh no, the other half has taken the battery to work for his e-bike..."
Well volunteered, when will you have them ready for sale ?
There is clearly a demand for such adapters .................
so I thought...There are actually millions of tool batteries languishing in garages.
And no-doubt a ready second hand market.
Got an old Bosch powertool battery ? So buy an adapter and sell the set for eBike use on eBay.
