Hi guys another one for your consideration!
Yes I know this topic has been discussed recently but you have all done some more running and experimenting since then I would assume!
NiMH, LiPo, LiFe are options you have all debated and all have their merits.
NiMH I already have experience of but God they are heavy if using SubC's for a high capacity setup.
LiPo's are now becoming available at 5000-5400mAh in compact 'hump back' form (LRP have released one).
These are considerably lighter than NiMh but do require the extra complexity of a voltage regulator.
LiFe I have no experience of at all and I cannot see a readily available supply of these in a compact form!
So, over to you guys.
