Re: Turn key 4s lifepo4??

If you ever find good ones wineboyrider let me know. Last question... can 12v camper DC accessories handle say 16v+ hot of the charger? I can't seem to find much online if this is the case. I'm thinking of using some other old Makita cells I have in a 4S, but that would make them 16.8v... probably f...

Re: Turn key 4s lifepo4??

Thanks for the replies folks. I was thinking prismatic or headway etc. and while I can do some DIY on it to save money I'd prefer to just get something pre-made. I see years later that while prices have come down a lot lithium 12v is still waaaaaay more expensive than lead. Thanks again.

Turn key 4s lifepo4??

Hey folks.. I've been out of the loop for quite a few years and searching around is a little overwhelming at this point so I'm looking for help. I'm looking for a ready built/turn key 4s lifepo4 battery of at least 40ah for use in a camper. I turned my old Makita tool pack cells into a 3s 50ah campe...

Re: Adopting Power Tool Batteries to Our Broader Uses

Re: Adopting Power Tool Batteries to Our Broader Uses

I can see the time when your bike carrier has three or four plug-in receptacles for a Makita or DeWalt or whomever lithium batteries. 7 years ago... Milwaukee V28 packs. Worked really, really well. Tool pack batteries haven't been as cheap as that since as far as I know. https://lh5.googleuserconte...

Re: Sony Konion 18650 with tabs

Word. I'm thinking of using my leftovers for a VW camper house battery to power my LEDs and maybe a 12V DC fridge, but LiMn isn't very conducive to "12V" charging. I suppose I could do 3S and limit to 12.6v somehow, but my VW alternator puts out like 13.6v-14v or something like that. Hmmm.

I found a “magic speed” on each configuration where you can run seemingly endless amounts of wattage through your hub without issue And that's just it... once you find the motor's sweet spot you're "golden". :wink: I've been experimenting & pushing a little with my 9C 2810 lately & dumped 2kw (18s ...

What's it cost to get a good quality setup for welding these with excellent results? Also, what connectors do you have to use? I just followed the "$100 Tab Welder" thread here and it worked great. I did add a better Scosche cap for better penetration recently, but it was only like $50 on eBay. Fin...

Re: New Konion cell 20C continuous 6.7C charge

I'll definitely concede that only needing a small Ah battery of 10Ah or less, then these Konions are a better choice since A123 are 20Ah. ;) I wouldn't argue that. If I needed/wanted 20ah or more I'd be all over the A123s, but putting 180 little konions into an 18s10p triangle pack with my little 2...

Fun experiment on the way home from work during the ~1,700ft descent. I wanted to find the no load/regen speed of the 9C 2810. It started to regen just above 35mph and was kicking out about 250-300 watts at 38mph. I got it up to 41mph very briefly about 500 watts and slurped back in a quick .1ah bef...
