I replaced my GT250 X7 battery with a lithium. The old gel battery was goosed after only 2 years. The lithium is a bit smaller and they provide foam pads to pack out the space. The X7 doesn't need power to start, but the indicators were a bit shit at standstill with the bad battery. And I'm hoping I won't have to replace this one as often.

I've also got a lithium on backorder for Smallkat. This one has overcharge protection.

For some reason I'm not authorised to look at that link. I am up to date with subs, aren't I?

It's a Skyrich HJP9-FP, I haven't fitted it yet. Weirdly, the battery itself does not say anything about overcharge protection, but the sales blurb did. I'd sell you one at trade price Rob, but I can't send batteries in the post. Trade is only about £10 cheaper than ebay anyway.

The X7 lithium completely discharged itself, so I have to investigate why at some point. Charging voltage coming out of the generator is ~14.5V, so all superficially looks okay.

I'm trying to get my VFR sorted out, which is taking up a lot of time. I spent days trying to fit the exhaust, I got it done, then realised I had done it wrong and have to start again. They are great bikes, but you need to bloody dismantle the whole thing to do any job on it!
