ok, thanks,
I have 6 batteries, they all have short flight time now, a couple of them down to 3 minutes, which is my fault for storing them charged, didn’t know the batteries should only be partially charge till I started reading up....but hey ho, that’s where I am now, so need a solution.
I have seen people ordering replacement batteries and getting batteries with less than expected life from a new battery.....probably because they were manufactures back in 2015 or there about. So I don’t want to buy new batteries that are already got limited flight time.
Has anyone tried modding something like a cordless drill battery, could my dewalt 5ah and 6 ah batteries do it if I used a voltage reducing circuit, whilst I understand lithium ion is heavier than li-po,

do you think the pack could put out enough amps, or am I just wasting my time ever considering it, ...because there will come a time soon when my solo won’t be flying because once the flight time is less than 10 minutes the batteries are not worth flyng anymore, be a shame to have to get a Dji just because of lack of batteries.
