Hi all. I have looked for similar questions here and have come up empty. I have been learning as much as I can about ev conversions to prep for my 1985 vw westfalia conversion.
I am wanting to maximize range as I am fine with this slow beast staying so. I have been looking at the hyper 9 or warp...
I'm in the midst of a EV boat conversion. Getting ready to order batteries and BMS. The batteries will be Lifepo4, 2P30S, 96 volt, 280ah each, 50+ kwh total.
I'm thinking the BMS should be separated one per series group. i.e. one 30s BMS on each side. If one BMS trips out (low cell or something)...
My truck went down in 2012 and has been sitting since. I drove over a year with the 200ah Calb lifepo4 batteries and decided to replace the manual tx with a 700R4 automatic and put in a larger motor. Just wondering what’s in store when I go to fire it up again.
Lots of rewiring and have to...
Does anyone have experience with these cheap batteries
3.2V 86A Lifepo4
here is another one Lifepo4 90Ah
I am very skeptical of anything battery related coming out of china. Is this 86Ah rating going to be correct or it will be more like 20Ah or even 5.
I need 8-10 3.2v cells to get my pack back up to the design voltage. I have 160AH Voltronix, about 5 years old. Looking for something in the that range of useful life to get my voltage back up to 144 after losing some to various issues. CALB or any brand is fine if they still have some life left.
I am currently working on a conversion and spotted these packs for sale on eBay. Now I know the dollar per kilowatt isn't that great on these, but I am trying to keep the costs low, so I plan to start out with a few of these for a proof of concept and then upgrade down the road...
Has anyone had experience with LiFePO4 cells from "Shenzhen KM Technology Co Ltd"?
I am looking at the KM-LFP34412-80AH model in particular.
As the model says, it is 80Ah at 3.2 volts.
The size is (prismatic) Height: 221mm, Length:137mm and Width:31mm
I will be fitting two of these in parallel...
As above, new or used, would also take the old 38120P or 8S of the S types (any format) or even LifeBatt X-1P.
Or if anybody from the UK wants to split and ship onwards from http://www.eclipsebikes.com/headway-lifepo4-38120hp-p-1094.html
Same problem with this and this - the guy still has some...
6 x 138ah 12v LiFeMgPO4 Valence Batteries U27-12XP 720 USD Cheap or expensive?
I am based in Paris, France and have a camping car for which I need auxiliary batteries and later plan to...
I am hoping I can get some info./assistance/guidance from some of you kind and knowledgeable folks... I do realize this is an EV forum, but I know you can still give me good advice.
BALQON = NO USER MANUAL or USER GUIDE = NO COMMUNICATION = MY 27kwh LiFEPo4 Battery...
It's been a while since the first LiFePo4 batteries have been installed on the EVs, and now, after a few years, I think it's time to draw some conclusions about the experience with different manufacturers: performance, cycle life, any kind of problems ...
So far I have noticed that many prefer...
I have a good amount of Voltronix Lithium Ion batteries I no longer have a need for and am looking to sell.
I have the following capacities available and at my warehouse in the USA:

They will most certainly be sold for well below market...
Hi-Tech industrial battery cell based on lithium technology - LiFePO4, high energy density and metal housing. Capacity: 20Ah, size: 71 x 178 x 28 mm, weight: 0,65 kg.

I have a large excess of brand new Lifepo4 cells in stock (in the United States) and ready to ship. They are priced to sell quickly, so if you are in the need for some cells or have an upcoming EV project this is definitely a steal. Here is what I got:
Voltronix 180Ah Cells
This last Winter I was busy installing new Lifepo4 batteries in my Saturn SC2. These replace the nine lead acid batteries that gave the car a range of 12 miles. Last weekend I drove the car 40.4 miles. I was thrilled to get that close to my estimate of 42 miles with the 36, 100 Ah cells that I...
Is just impossible to find a BMS for LiFePO4 so I decided to design one for my Off Grid house.
It is specific for my needs so max 8 cells in series and can use solar PV panels up to 40A to charge the battery. I have 8 cells 100Ah GBS not that great in therm of discharge rate but more than enough...
I have just come accross these batteries which have some impressive specs (not sure on the price yet). Has anyone had any experience with them before?
The 40160 looks extremely impressive, including the charge and discharge rates...
Working on the conversion of my 67BGT. I've created a blog
I'm going with AC Motor (may be I got scammed) and LiFePO Batteries
I'm hoping to get to 70mph max. 80miles Range @55mph.
The Progress will be updated here with a post, but details in the Blog above.
**UPDATED: CELLS SOLD**
I have GP45EVLF (Gold Peak LiFEPO4 lithium ion prismatic) cells available for sale. These are very powerful cells and are great for any EV conversion or stationary application that needs serious amperage.
