And when I get off this bed again in 2? weeks I will measure the width if the salsa chairs battery compartment sat 4 feet away.

Unless someone can do this for me easily? Anyone got one in bits that understands mm properly??

They are each 130 wide, So 2 is the same as an MK. the ones you link to are 135 wide. So need to be turned around. And then you get 150Ah rather than 210Ah with wasted space on 4 sides.


If I ran two columns side by side and eight across it would be CLOSE, that wasn't how I was picturing orienting them. The 8 cells in the columns would be 11.65" or ~296mm, My battery area is about 13.66" wide side to side, or 347mm. So would fit easily with a couple inches to spare. Plenty for insulation, ballast ect.

The tricky part with my battery area is front to back. it has only 10.25", or a hair over 260mm. Not enough room for adequate insulation. I could mod my battery area with out a TON of hassle to give myself room for 10.75" front to back, in which case there'd be room for insulation. 210Ah, that would be IN-FREAKING-SANE!!! I could get two weels+ on a single charge in the winter LOL! But would take some work. I can't read Chinese but looks like those 105Ah cells are 195mm tall at the shoulder and 200mm to the terminal. Same as those 75Ah cells I believe.

Honestly, my 90A Headway pack I've been using since last summer has been awesome. Rarely leaves me wanting more, though it does occasionally happen that I know to stop sooner than I'd like. Either way, beats the hell out of lead bricks. So for me, jumping to a 150Ah pack would be a huge 60% more capacity jump. And extremely easy to fit.

A hair over 260 is all you need. An extra 3.6mm to be exact, or in analog 1/8th inch. That allows a plastic or polyethelene 1mm sheet (credit card thickness and a bit) in the 3 places its required. One between the two centre cells. And one down each side. So how much is that hair EXACTLY? If its 3.6mm you are good to go. To give you an idea, on a typical 100dpi PC screen you need this much extra __ and that is 5mm! You need just 3.6!

3 bits 1mm thick, x 200 tall, and 305mm long. Thats one down the centre, one each side, taped or glued on with contact adhesive.
Then...
2 bits 1mm thick, x 200 tall 263.6 wide. For the other two outer edges.
Then... As cell dividers, 14 bits 1mm thick that are 200 tall 130mm wide.
Then a BOTTOM that is 2mm thick, and 306 x 263.6mm to sit the whole thing on.

A smear of silicone RTV or contact adhesive to attach the sides, seperators etc. Then tape with duct tape or fibreglass tape all the outer seams or corners just in case. You will then have one solid brick. 200 tall, 307mm long, 263.6 wide. Or change measuremets a little and have 2x 210Ah 12V ones. Or two 105Ah 24v ones...

Heres why I think you will not have an issue. https://www.tayna.co.uk/leisure-batteri ... x/xdc24mf/
Some group 24 batteries are a few mm smaller or larger than 260mm. 252 up to 266 seem quite easy to find. So they must fit.

Burgerman wrote:MEANING that you can fit 210Ah in place of lead, provided that you have JUST 4MM mm extra width available over a grp24 battery.

The math:
Cells are in mm:
130.3
37
200

37 x 8 = 296
37 x 4 = 148

We have a 240mm tall box. With 260 (or more) x 340 (or more although this way not an issue)
Arranged as
||||||||
||||||||
2 side by side is 260.6 (plus 3mm insulation from 1mm sheet so 263.6 total)
8 deep gives 296 (plus 9mm insulation so 305 total)

So with careful measuring it might just fit 16 cells.
210Ah in place of 74 (45 to 50 usable) So 5 to 6 times stock range. For £512

HOW MUCH will this cost to ship to UK in pounds for 16 cells and a huge 210Ah pack?
Thanks!



cheers

What about slo boat?
Is it possible?

Because the 6.75 kg is more expensive than the cells. It may be cheaper to send my ex gf to hong kong or china to carry back in her handbag :cussing

Cell weights 1980g.
16 of them will be 35Kg , including packings.

Post office won't take batteries . :fencing

237 shipping + 16 105Ah cells = 750 uk pounds for a 210Ah pack. Still good price! I just need a salsa accurate measurement.

237 shipping + 16 105Ah cells = 750 uk pounds for a 210Ah pack. Still good price! I just need a salsa accurate measurement. And will then order.

So lets see.
Salsa claimed range is 27 miles. From a 70Ah grp 24 at best you get to use 45Ah.

So with 210Ah, and use 200 for safety, from the lithium, you get around 4.2x better range.
27 iso standard miles, becomes: multiplied by the 4.2 = 113 miles. Or 182km.

So for £500 you get 2x MK, and 1 years use, and 27 miles.
For £750 delivered from china, you get 113 miles and a 6 to 10 year lifespan, fast charging in a few hours, and save 50lb of weight.

On second thought , 105Ah cells are rare and not heard of any review . Not worthwhile .

90Ah one is better .

Too little information about this cell and seller .

The safe way to go for it, if you insist , is to buy from dealer direct . That would be expensive and couldn't get the best value for money . Isn't it the the only reason to buy Chinese products ? banghead

Here's a pic of my battery case.

Image

I got ~10.25" or 261mm. So I'm pretty sure I'd need to mod it a bit to to fit those 105Ah(or 90Ah) cells. I got about 1/2" I could extend that rear panel back before it would be close to interfering with the rear casters. That would give me 10.75" and the mod wouldn't be too difficult. But still, its more work.

The 75Ah cells on the other hand, I could fit 16 easy. 16 of those is still a 150Ah pack. And no mod required. 210Ah is great, but realistically, how much real world day to day benefit would a pack like that be over a cheaper 150Ah pack. I don't think I could use up 150Ah in a single day if I tried. More likely a charge would last me two or three days in most cases in the summer.

Throw away that analog stick at once! :fencing

You need 260 plus 2 mm for a perfect fit. 1 cell, 2x 1mm sheet. To fit 8S. Presumably there are two battery compartments? And no protruding bolts.

May I suggest some 1 inch x 1 inch metal bars and a jack.

No, one big battery compartment, holds two G24 MK gel. And some protruding bolts as seen in pick as seen in pic.. This made fitting my 90Ah headyway pack a bit tricky. I lined the entire thing with a layer of 1/16" rubber rubber, and a layer of plastic drawer liner before installing my pack.

With the 75Ah cells, I like the extra space around the cells in my battery box. I could even put the pack in its own custom enclosure and set it inside my battery area. Plenty of room in there on all sides for that. Only way to do the same with the 105Ah cells would be to mod my chair to fit, Do you not think a 150Ah pack is enough with those 75Ah cells?

You only need 2mm Just over 1/16th of an inch in analog. You can make the battery compartment that tiny bit bigger. Jack it apart.

The rear of the battery box comes off with 4 bolts. I'd need some type of spacer, about 1/2" of room it could be moved back before the panel would begin to interfere with the rear caster pivot space. Maybe my nephew can make something with his 3d printer?

This is the fag end of 120Ah battery discharge. The voltage is all over the place. :shh: After charging to full, I initially discharged 105Ah through a Turnigy wattmeter to 24v truck halogen lamps.Then connected to pl8 and discharged the remaing 7.8 Ah till charger stopped on cell #6 voltage.

Also the charging data after the above discharge. :shh: :problem:

BM's opinion please. :argument
