Guessing it’s just because so low and won’t be cause for concern, but will be keeping an eye on that. They don’t “continue longer than 1 minute” so maybe all fine. If that’s wrong and I should be panicking, advise appreciated! ---

Agreed, one to watch. If that occurs every time I’d probably be looking to abandon that battery 😕 ---

That’s quite a variation between the three cells, at the end. 3.283 3.096 2.620 Irrespective that some people say a deep cycle doesn’t make much difference to these batteries … with those variations I’d certainly give it a go. Nothing to lose. ---

Seeing as that one was literally on 0% I guess it’s had one regardless. ---

With lipos anything under 3v per cell means it’s toast and won’t perform as well again in the future. I would just bum that battery off and replace… 4s are only £20-30 each ---

These are MP batteries. Difficult to be so blasé about £90 ---

HOW MUCH!!! I can build a whole quad for that! Or get 4-5 decent batteries. Dji really have got there users over a barrel ---

And if you think the Mavic 2 battery prices are bad, check out an Inspire battery cost 😱 ---

Imagine the cost of a new battery in a Tesla …. 😛 If only lead/acid batteries weren’t so large/heavy - the thumping great thing in my Shogun only cost £90. ---

Yeah I think I’ll try to recover it before giving up! It would hurt too much to let it go. ---

Yeah DJI batteries are a rip off, £110 for Mavic 2 battery which is basically a 4S 3750mah pack. You can buy a good quality 6000mah 4S lipo for half that price. Your paying a huge premium for a plastic case and some very basic electronics. ---

Hoorah. Nice slow stress free flight on that battery showing no issues. ![image](https://d1q8cepst0v8xp.cloudfront.net/original/2X/4/4b8ed416bdbbba60a089399c8b77b2a04197b39c.jpeg) ---

Agree Dave, love it. Don’t like spending me money, but upgraded to Gold for the extra reports etc. Think I got 13 months for the price of 12 and a 20% discount on first year subs. Well impressed
