Yes lithium will cost 3x that. And a carger setup. So not cheap.
But 3x the cost will allow 3x the range and about 3x the lifespan.

Burgerman wrote:Yes but you dont want a battery the same size. The whole point of lithium is that it possible to fit more Ah into the same physical space. Its more energy dense than lead. And much much lighter. As well as the fact that every Ah takes you about 1.7x as far.
So for eg I have 120Ah in my BM2. In place of its 55 or 70Ah lead.
So if its 70Ah lead battery took me 20 miles, the same amount of lithium 70Ah would take me 1.7x 20. So an xtra 14 miles. Thats 34 miles. But its worked hard meaning its not going to live very long.
But since its possible to fit 120Ah in 5the same space, which makes the battery live a longer life as its not worked hard, then I get also around 55 miles or more. AND a battery that either needs charging half as frequently or that just doesent work as hard. So it lives a very long time. So plan on fitting as many Ah as you can fit.

I didn't think of that's not a bad ideaex-Gooserider wrote:Worth noting that if you do the conversion properly (the way BM says... ) so that you end up with a nicely balancing pack it takes several weeks, so best to get started on the project early, before your existing batteries start to die...
On hindsight the scooter is quite well made, and as they've been on the market for a few years there's quite a few 'used' ones on eBay for not a lot of money. I've noticed with scooters is that often they're purchased for or by an older person, then only used a few times because the older person doesn't feel safe and sometimes they get unnerved because they crash into a gate post and crack the bodywork, etc.ex-Gooserider wrote:In terms of repairing you existing scooter, it would probably be quite expensive to replace the motor with a new one through the dealer, but often it is possible to by used parts (or even an entire replacement scooter) for pretty short money on ebay or other local sources.
ex-Gooserider wrote:If you size your packs to be about the physical size of the existing batteries in your current scooter, you also have very high odds of being able to simply swap them over into a replacement scooter of similar size since most scooters of a given size / capacity will use the same size batteries.

LROBBINS wrote:Most of the time is for fully charging each cell, letting it self-discharge for about a month, re-charging while measuring how much has to be added back, then sorting the cells into groups with equal self discharge rates. That's what gives you a pack that charges and fully balances quickly. In other words, lots of hurry up and wait.
Good ideaex-Gooserider wrote:Another thought on lighting - not sure what the laws are in the UK, or other such places, my understanding in the US is that it isn't technically legal but generally nobody will bother you, - is to use a strip of 2812 or similar RGB LED lights, and a controller (you can do a custom job with an Arduino or get pre-programmed ones cheap from China)

Can you for example buy a group 24 lithium battery where all the work has been done for you?
