G'day fellas.
With Boyer ignition a 4ah battery will give me an hour if I don't touch the brake! Brakes only slow you down anyway!
Cheers

I only fit Cyclons now days. You can't beat the spiral cell technology for robustness.
Yep, a truly fit and forget item.

didn't work out for me, I had three (6-volt bike and 12-volt bike) they all worked well for a while then lost voltage and would not charge back up to full 6 volt, can't recall all the facts now but maybe some went flat, they then become difficult to get charged, also note on my cordless mower (LI-ion) that the two batteries should not be used  together unless both are at the same level (voltwise) I used to swap the cyclon around a bit , might have had an effect

I'm goin to give Swarfy's cheapo Toolstation alternative a punt, as I need one quick and haven't got around to ordering one from Goffy yet and my local have one in stock. Even if it only lasts a couple of months it's only nine quid so nowt lost.
I'll report back on how well it works etc.

I've just measured my old battery and it seems that I can fit two of the toolstation batteries in the battery box, if I did this and connected them in parallel, would they still charge ok from the dynamo or is there something else I'll need to do? They are 6 volt 4a/h.
Kind of academic at the moment as they only have 1 in stock, but if it's a dead simple plug and play scenario I'll order a second one.
Cheers folks, and happy new yonk!

If my school science/maths is still relevant these days Minto I think you should end up with 6 volts 8 ampish

I do this with very similar cheap batteries in the Norton without a problem. I ran the A7 with them for a few couple of years without issue, but swapped out to a higher amp hour setup trying to improve the lights (that did not work).

This setup has been great, and those never discharge when left alone, and no risk of leaks.
