Vapecige Battery option !!!

[Popeye]

I know there are a few people waiting for news on a good one that fits, but i can confirm that the Turnigy nano tech 1300mah DOES fit and it is a massive upgrade.

Useable battery life has doubled for me, even at higher wattages.

The exact battery is the 25-50c battery, the higher one will not fit.

I didn't like how tight the connectors were (fitment wise, inside the box) so i got rid and soldered the battery straight to the board.

This one does fit, but you will need to swap the connector over, or solder it to the board.

I just ordered one, my luck with mine finally ran out. Still works but #3 cell is out of whack.
Thanks for the info.

So here is a screen shot of why I'm replacing the battery although I'm not exactly certain that the battery is the problem. I disassembled it this morning and found some kind of crude built up on #3 solder joint of the balance connector. I probably should have re-soldered it after I cleaned it off but it looked good.  I'll find out when I replace the battery I guess. I tried charging it with the rc balance charger that came with my Hotcig DX200 and all it did was overcharge the two good cell to 4.28 volts. Since failure charging with little RC charger I'm pretty sure now that the battery is at fault here.

For diagnosis, consider measuring the voltage actually on the balance connector pads versus what device manager reports. If they differ, it's the board; if they don't, it's the battery or wiring.

[dwcraig1]

Well the pack voltage is down by the same amount as cell 3 when charging is completed.

[dwcraig1]

After installing the new battery I will do that if it's still out of whack.

[dwcraig1]

I removed the battery and measured the pack voltage with my meter just in case the pack voltage was the sum of the cell readings, it was low.12.2 volts.

[dwcraig1]

So after installing the new battery all was well.....at first anyway. After leaving the mod sit unused for a couple of days cell #3 is at 3.90 volts while 1 & 2 are at 4.20 volts (after charging). I'm really not sure but I'd guess that the board is draining down #3 when not in use. I see quite a few posts with a similar problem. Anyone got some ideas?

[dwcraig1]

So I gave my first "bad" battery to my friend to balance it with a real RC charger, when I get that back I'll swap out the 2nd battery and do the same with it. I'm pretty sure the batteries are OK.

any advice on taking apart the battery on the DX?

just ordered the 25-50c 1300 pack but i have no clue how to open the battery portion. 

 

just looking for some tips. i dont see a screw to disassemble unless its under the sticker. 

[Popeye]

Got any photos? Im not familiar with the dx

[zdogefizzle]

yeah its the hotcig. for some reason i was thinking it was the same manufacture. but i might be wrong now that i look into it lol     

[dwcraig1]

^^^ if your thinking about using this battery it won't fit.

The battery that Evolv sells is the correct dimensions. $19.99-FullyMax FB900HP-3S 
You can find it else where for less.

Any advice on disassembling the battery? I'll put the 900 in it. I can't find a screw or anything to start with.

[dwcraig1]

There is a small torx head screw under the label just above the two banana plug holes just below the " + and -", the cover just slips out from there, just a tab in a slot at the top.

Dude that helps a lot! Awesome that hot fire isn't very good I bet lol. I appreciate the advice!

[dwcraig1]

I have two of the hotcig dx200 batteries, the one that came with the mod  and an extra from Fastech. Both arrived healthy. no complaints, I have an Opus also to compare to. just saying as there were a bunch of bad Hotcig ones.

[zdogefizzle]

Mine didn't come dead. But it was severely imbalanced. After a few cycles it seems to be ok. I've got nothing to compare it to but I feel it could be better. I should probably compare my battery analysis to others.
