Lithium batteries - What's your opinions?
It seems we are very restricted with the rules when it comes to lithium batteries. See the MSUK Gold Book here.
I have been trying to get a hold of a new lightweight Rotax battery for some months now, with all retailers being out of stock. Which comes to my points below on the current state of the rules and regulations on batteries, supplied by MSUK. Here below you'll see an email I sent to them over the weekend.
I just wanted to know what your thoughts are? I wonder what the response from MSUK will be? I'll keep you all in the loop.

Hi Guys!
I am after some advice and help if possible, it would be very much appreciated.
In the current 2021 Goldbook for Karting, page 44 section E2.4.7. Regarding the Rotax Max Senior class, it currently states the following:
"ONLY the ROTAX lithium iron phosphate battery RX7-12L or RX-12B may be used as an alternative to lead acid batteries."
Now the RX7-12L as you know is manufactured by Super B, of which we still can't use even though both batteries are identical other than a Rotax sticker and the price! My issue is that this RX7-12L & RX-12B battery is out of stock everywhere, I cannot buy one from any UK retailer at all and have been looking for months. Which is very frustrating as there are many well-known branded and identical batteries on the market, which can be bought but not used due to the current regulations. Not to mention much cheaper! For example Exide make a Lithium Ion 12V Battery of the correct spec, dimensions and size which weighs just 680 grams - which cost just £100 - affordable.
Many places are showing this RX7-12L battery as out of production. Super B also now do not list the non Rotax variant on their website either. So I assume this is the case!
Which now leaves us Rotax Max drivers (Other classes too) with no other options for a lithium lightweight battery? At some point will the rules be updated to cater for use of other lithium batteries or will the battery go back into production?
Any help much appreciated
Thanks
