[QUOTE="rodagaster, post: 441968, member: 12998"] Hi mate i had a look at the voltage convertor and i think you may be better off going with a smaller step up the 7.4v to 9v is okay but the 14.8v to 37v is a 22.2v difference ,and with only 4 batteries you wont have a big amperage also a fully charged li-ion like the 18650 is 4.2 v and you normally discharge to 3.7v you can go lower but you reduce the life of the battery ,as a example i have built a few packs that are 3 in series by 5 in parallel which gives a voltage range between 11.1v to 12.6v with a amp total of 21amp 2 of these packs together in series will give you 25.2v with 21amps and so on , and that's what i want to do with my garret i would love to get a wiring diagram of the machine then i will make a pack for it with the charging of li-ion you need a special charger but on ebay they are around $25.oo and called a b6-imax very easy to use i have put a couple pictures up so you can see what i'm talking about cheers .[img]https://www.prospectingaustralia.com/forum/img/member-images/12998/1538046997_img_0256.jpg[/img][img]https://www.prospectingaustralia.com/forum/img/member-images/12998/1538047071_img_0255.jpg[/img] [/QUOTE]
