What ever else please don't argue unnecessarily you have both been helpful to me. Now I just need to find a source for a reliable controller and thumb throttle (with voltage read out) from a trustworthy seller. I guess China has a monopoly on the sort or stuff I can afford.

I think they are in the right direction. I mentioned the depth of discharge thing, do the Ah figures for lithium ion quote the realistic the energy you can get out before the battery management system cut off? So if your 50% DOD means a lead acid 12Ah battery only delivers 6Ah to 50% dod and...

Yet we know lead acid will lose life if taken below a DOD of 50% Thanks both for the figures, I'm already sold on LiPo batteries but only have one on order to complement some PV panels. I do have a cheap Aldi 4" angle grinder that uses their 40/20V lithium battery, it's impressive and 2.5Ah at...

If you order three the checkout price including VAT and delivery is £55.92 as they only charge for one delivery, so £6 more than my rough figure.

In principle what are the differences between lead acid and lithium performance? I get the impression that a 12Ah lead acid can only be taken to 50% depth of discharge whereas a lithium one can be discharged further, so a smaller lithium could be used for the same range?

Thanks I'll check that. I agree it's not worth investing much but ii this the sort of thing? https://www.ebay.co.uk/itm/383623387571 and a thumb throttle about another 12 quid brings total spend to around £85, may be worth it, not sure. I don't like the idea of throwing it away. Is the...

@gerryg doesn't seem to have returned with any results after the controller repair resulted in constant full throttle. I'm in a similar position with my old bike, my wife briefly used it 14 years ago but stopped cycling so I lent it to a friend, now it has been returned in a sorry state...

Hi I popped in for a bit of advice on a very old Powabyke and will post a query there
