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

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: 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...

So I have a bunch of IMR-26700AB cells salvaged from Milwaukee battery packs. I get about 1.9ah. Disappointing because they have a stated capacity of 2.6-2.7ah.. I never saw very good capacity in any used emolis I ever played with. Typically 3C sustained discharge and 50-75% rated capacity was norm...

Re: El Escalador De Montaña Grises - Season 4

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...

Well I figured out why I wasn't seeing the speeds/power I thought I would and it's to do with an early model Cycle Analyst that I have. Since I have a CA 2.0 and a 9C motor with 23 poles there are some revisions that need to happen in order to have accurate figures. 2.0 CA's can only recognize 14 po...

Okay never mind... I figured it out. I have an original Cycle Analyst 2.0 and had a programmed top speed of 30mph for years as that's the statute in Montana for ebiking. Well... since I have a 9C with 23 poles and the old CAs can only register 14 poles I was only seeing 14/23rd my potential speed......
