cooper99 Posted July 7, 2015 Report Share Posted July 7, 2015 Greetings. I'm planning on installing the board in a CNC'd Hammond 1590g size enclosure. I would also like to be able to swap in a fresh battery when the need arises. I know I'd need a charger as well but I'm okay with that. Not sure what else I would need to make that possible. The battery I'm looking at is this one because according to the specs it's only 20mm thick which should be a good fit for the box. Any thoughts would be appreciated, is this a quality battery,etc.https://rotorquest.com/index.php?route=product/product&path=2064_31_1981&product_id=106383Many thanks.John Link to comment Share on other sites More sharing options...
syst3m_f4ilure Posted July 8, 2015 Report Share Posted July 8, 2015 hi, would this battery work well for the DNA200? http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9608 seems to be a powerful & compact thing Link to comment Share on other sites More sharing options...

alee132 Posted July 8, 2015 Report Share Posted July 8, 2015 I am going to be using a 950 mah 3s 11.1 turnigy nano tech 25c in a 1590a with mamus faceplate. Just waiting on shapeways to ship faceplate. Link to comment Share on other sites More sharing options...
combatwombat Posted July 9, 2015 Report Share Posted July 9, 2015 So this http://www.maxamps.com/proddetail.php?prod=Life-1050-99-ERevo-Pack is not good because it is 9.9v? Link to comment Share on other sites More sharing options...
John Posted July 9, 2015 Report Share Posted July 9, 2015 Oh no, that one is fine. It is just LiFePo4 instead of LiPo. Just select that chemistry from the dropdown in Escribe and it'll act appropriately. Link to comment Share on other sites More sharing options...

VapingBad Posted July 10, 2015 Report Share Posted July 10, 2015 You can get 25Rs with solder tabs, Ecoluxshop in eBay UK used to carry them, not a fan of soldering onto cylindrical cells, but understand it is a proof of concept thing. Link to comment Share on other sites More sharing options...
KTMRider Posted July 10, 2015 Report Share Posted July 10, 2015 About 25 yrs ago, I used to build my own battery packs with sub-c's for r/c cars. If you have a good soldering iron and not heat the battery too much, soldering on the contacts is fine. Use flux to tin the contact, tin the wire and then solder them together.

John Posted July 10, 2015 Report Share Posted July 10, 2015 Looks okay to me Lollerwaffles. Nothing wrong with building a tapped pack out of 18650s if you do it well. Besides, you're using Kapton. If you wanted to cause concern, what you want is masking tape holding bare wires to the ends of each cell. Link to comment Share on other sites More sharing options...
VapingBad Posted July 10, 2015 Report Share Posted July 10, 2015 Fair enough I'll shut up then lol I was just concerned with noobs trying it with a 15 W iron and keeping the heat on too long really. Link to comment Share on other sites More sharing options...
combatwombat Posted July 10, 2015 Report Share Posted July 10, 2015 John when you said, "Using LiFe the max output voltage and the battery cutoff are lower.", does that mean it will not perform on par with the 11 v batteries when chip is set to higher watts or certain preheat - punch settings? Also with the battery cutoff being lower will it over-drain the batteries which could damage them? I just dont want to limit the potential of the chip with the LiFE battery... thanks.

John Posted July 10, 2015 Report Share Posted July 10, 2015 The max output voltage becomes 8.5V when using LiFe. The outputs, charge voltages and cutoff voltages adjust appropriately when set to LiFe mode. So no, other than not having quite the top end for high power high resistance coils, there's no performance hit. Link to comment Share on other sites More sharing options...
lolerwaffles Posted July 11, 2015 Report Share Posted July 11, 2015 I'll pass on lifepo cells then. I was considering using them, even with the lower mah/gram. Link to comment Share on other sites More sharing options...
combatwombat Posted July 11, 2015 Report Share Posted July 11, 2015 I think the 9.9v lifepo fully charged will 10.4v? So using lifepo batteries will drop the max output voltage only by 0.5v, doesnt seem too bad? John are you talking about top end (150-200w) and high resistance coil (3.0ohm)?

John Posted July 11, 2015 Report Share Posted July 11, 2015 Really what you end up doing is dropping the max resistance for 200W from .40 to .36 ohms. Or about .20 to .18 temperature controlled. And only when the battery gets near dead. That's the only downside. Link to comment Share on other sites More sharing options...
combatwombat Posted July 11, 2015 Report Share Posted July 11, 2015 Thanks, I just wasnt sure how severe the tolerances were between the two chemistries of batteries. Now the only downside is the size of the lifepo but I plan on keeping the dna200 at home and using dna40 for mobile, so i can have a huge case. Im tempted to make a a123 26650 3s pack but my arms might get a workout just from vaping on the beast. Link to comment Share on other sites More sharing options...

Cotay Posted July 12, 2015 Report Share Posted July 12, 2015 Regarding the Turnigy 1300mAh 25C, keep in mind that some people have received examples that have been 2mm-4mm taller than the stated specifications. I have two and they are both just shy of 74mm tall. Link to comment Share on other sites More sharing options...

malcbzt Posted July 12, 2015 Report Share Posted July 12, 2015 Thank you for the info. I am in Eu, Croatia. Will try to get some from some Eu sites.. will this battery last one day of 50W vaping like one 18650 2.5Ah or close? Link to comment Share on other sites More sharing options...
