Again I'm not convinced about all the folkllore concerning lipos. I've heard of loads of people that let their lipos go down too far without catching fire when they charge them.
I think most of the folklore came about when their use became widespread in the RC world. There are some real horror stories about them that may or may not have come about by shorts etc but certainly coupled with poor early batteries and lack of knowledge in handling and charging they where/are potentially dangerous....just three of many on rcgroups....

Thanks for all the technical info you guys know your stuff. I can see why these batteries are not used in commercial applications just overly complex for the average user.

I think if I do build a few bikes for people then I would go down the BMS Battery route it seems a good way to build a competent electric bike on a budget. I like the look of their frog batteries they seem similar to ones used by Electric wheel and other components seem to be used by other electric bike resellers.

My bike has evolved slightly in that I now have an IP68 plug in the top of the battery bottle and the weight is now 13.6kg. I have to say its an absolute joy to ride and really zips around 0-15 in just a few secs up the hills no problem at all.

I'm just checking out the range now up to 8 miles and 3.89V. Who knows with enough interest I may turn it into a little side line business based in Exeter, not sure if there are any members in the southwest?

We have a number of members in the South West, in Devon, Cornwall and Somerset. Most are only occasional visitors to the site. That region isn't well served with e-bike handling cycle businesses, but there are the odd exceptions.

Our members map on this link shows 14 members entered in the region, predominantly in Cornwall. Click on their bikes to get their details
