Converting my Dewalt 12v drill battery to Lipo

[ricglos]

lipo batteries NEED ventilation!! Maybe you should put a row of holes in that case so it wont overheat, and that goes double for the 3000 lipo..

@ricglos good point. thanks. However, for others who are reading this, Unless you are drilling hard for the duration of the lipo pack and nearing "C" stated ratings of the Lipo it is not needed. Most of my drilling I'm doing, I'm pulling no more than 5 amps from a 1300mah rated at 25C or 28amps continuous so the lipo does not even get warm. Anyhow, it's a good idea to check temp and if it's getting hot, drill the ventilation holes.

how much was the lipo battery? i heard you say 3s 1300... im looking to do a similar project and wouldnt it be 11.1v?

@JeffPProductions Actually the 3S Lipo fully charge puts out 4.2v per cell for a total of 12.6v. If you aren't doing any serious drilling (screws, drill bits), 1300 3S I tested will work ok. But if you do use it for hard drilling you'll need a bigger Lipo battery or a Lipo that has a higher C rating. If you view my other vid, amps on the drill at max load was hitting 40amps. If I do any serious drilling I just strap on my 3000mah Lipo and drill away. see description area for link to lipos
