I'm totally new to this so please excuse my surprise at the price of batteries. It seems totally odd & wrong cost / environment wise that a new battery pack with Alu case & charger etc can be cheaper than a shrink wrapped set of new, decent batteries. Perhaps the market is too small or the...

Thanks for the reply, I've seen a 10AH Yose Power replacement for £159 or a 15AH for £192 on eBay but that's the whole thing including a new Alu case & charger. I was hoping to just get a battery pack that I can slot into the case for a bit less. Does Aliexpress now include VAT?

Just came across this thread, looked in my gmail spam folder & found a whole lot of Pedelecs emails! Hopefully I've now set a rule to make the forum emails come to my inbox instead.

Following on from my earlier posts in the general discussion area of the forum, I came across this Technical area. Apologies if I was posting my questions in the wrong place, the replies have been very helpful but thought it might be better to carry on in this section. I have a BatriBike Breeze...

I've rigged up a single 12v bulb to discharge the cells one by one and will see if the re-charge brings the low cells back up. I thought that the BMS would try to bring the low cells up, but this test will give an indication. If this fails, I'll look into charging the low cells individually via...

That's an interesting thought and well worth investigating, the low cell has held it's charge perfectly overnight. However, does the BMS not charge the cells individually? I have good access to the individual cells as the pouches are connected via flaps. Do I understand correctly, the idea...

Many thanks to all that replied and for the help towards understanding the problem with the battery. I think I've now got to the point where I understand what's going on and why I get the confusing results. There is one cell in the battery that only charges up to 3.5v while the others charge to...

Apologies for my newbie question, who is 'Jimmy'? Thanks

By chance I have a few 12v halogen bulbs that I didn't get around to throwing away. I linked 4x 20W in series and the battery cut out after a few minutes. Cycling the power switch gave less & less time before the cut out. I rigged the meter so that it was permanently connected and it looks like...

I've taken the battery out of it's case to measure the cell voltages. My battery appears to have 10 rectangular LiPo cells approx 70x140mm, as opposed to cylindrical cells. I put a 240v 40w incandescent bulb across the terminals and after more than 3 hours the voltage has dropped approx 0.5...

Thanks for the reply, the battery is suspect due to the bike's age. But what has me puzzled, is why does it then show a full charge at the LED display & also at the battery charge indicator after switching off & on again?

I've just bought a Batribike Breeeze, it came with a known problem that I hope someone here can help with. The drive cuts out after a few minutes & needs to be switched off, then back on to restart. The first cut out happens after 3 or 4 minutes of riding, after switching off & back on, the...
