They have their 10ah 4s packs on sale for half price, $30 each now. I ordered 6 of them. That's 20 cents per wh.
I'm having the same reaction. If I had ordered that many, I could fit 12 batteries (40Ah) in my saddlebag, with room to spare.dirkdiggler said:I can't believe the size of these things! Wow. .... double the AH in the same space as before.
Found it, thanks!Alan B said:Photos in my CroBorg thread from early in this year.
Knock on wood, no puffers yet. But I've only taken them on a couple hard rides so far. None of the six had any low cells when I first got them, so maybe I got lucky.bionicdan said:Has anyone else had puffers yet?
wesnewell said:No puffers here, but I haven't even used them yet. Just got the bms for them and haven't got a 24s charger yet. I'm going to cut off the XT90's and replace them with 4mm bullets before I wire them to the bms. I did just depuff a 3+ year old 4s hardcase pack and its held up good for a couple of cycles.
Which one did you buy, jkbrigman? (And also interested in knowing which one Wes bought.)jkbrigman said:Also: what's your BMS? I bought a BMS and am considering adding it to my LiPo.

wesnewell said:Depuff means I took a small straight pin and very carefully poked a hole in the foil punches to squeeze most of the air out of them and then took some packing tape and closed the hole.
wesnewell said:Well, I'm kind of reckless, just be aware that if you stick that needle in to far the pouch could ignite on you. So be very very very careful not to do that. I just happened to have a straight pin handy. Something sharp and non conductive would be a lot safer.

I did the outside cells in on the flat sides and the inside cells on the edges. I tried to puff the section here I was going to poke first by squeezing the cell in other places.jkbrigman said:Agreed. I regard this operation as being extremely dangerous. I have some spare cinder blocks I am using to make a small platform and do the work on that platform.
I was going to angle the pin as parallel-to-the-wall of the cell as possible to keep it away from the battery internals. Does the location of the pin prick matter?

DAND214 said:I did my puffers at the top along the side under the fold. Pinned it almost at the top and hot glued it shut folding over the flap. No more puffer or any leakage. that is on the Turnigy 6s 20c packs or 4s hardpacks. Not my Multistars. I sure wouldn't think you could draw enough amps with a 6 fet that would hut the Multistars.
