2 x LG M1J 3500mAh cells bought from 18650.uk
Practically brand new, only used a few times
£10 posted, UK only. Will be sent in individual protective cases via UPS.
UPS price is sadly ruining it since you can buy 2 of them brand new for £9 ish delivered (using codes) although they are oos at the moment.
I would have had them other wise. Thank you for the kind offer though 
Mine always arrive via Royal mail whoever I get them from - I don’t know how that happens as it clearly says batteries on the jiffy bag lol, yet local PO’s get all fussy about it when trying to post.
Looking at RM’s guidance -
‘lithium batteries when not sent with or contained in equipment’ - I guess cases count as contained in equipment is how it works.
‘Do Royal Mail accept lithium batteries?
The equipment sent with cells or batteries must be packed in strong rigid packaging and must be secured against movement within the outer packaging and packed to prevent accidental activation. Lithium Battery Mark must be applied. The sender’s name and return address must be clearly visible on the outer packaging.’
Fiver then just for you 
Go on then. :+1: Thank you. Read the above, it seem you would get away with sending them in those tubes, up to you though
