To keep this on track. (Or being a Challenger, probably detracked). I have ordered a pair of 3S batteries. £19.95 for one, £22.95 for two, with free delivery Go figure? So not the best quality then from Amazon. But I’m not paying £22 delivery on a good quality battery that was £30 despite the price including free delivery to main land UK. Ah! But you come under Highlands and Islands sir. We are an hour outside of Glasgow, so hardly remote. I have also taken into account that as these are probably not the best quality, I will ensure they are in charging bags, only charged when I am present, on a suitable charger, and charged at low current.
Anyway, this will be a little experiment to find the speed differences between, batteries, 2S, high speed, 3S low speed, and 3S high speed, using the setting on the controller.
Given the warnings of others, and the work I put into it, I feel confident, that if driven sensibly, and not driven flat out over unstable terrain it will survive, the odd high speed dash in a straight line.

Ohhhh you go with your bad self Mr. Rat! I totally look forward to your experiment, hopefully cool pics and vids and of course the obligatory results/repair posts...

I’m sure there may be some.
