battery stuff

[Marmalade]

An electric bike with a 24V-8.5AH Lion Battery pack.

Would it be possible to use 2 of these batteries YUASA 12V 8ah ran in series for 24v to run it?

Any foreseeable issues?

Apart from weight no.

I will be writing a thread in the show & tell soon on my DIY electric bike, incudling making my own LiIon battery out of laptop batteries.

I'd say probably be fine, but you need to check that the max continuous discharge rate for the lead acid is the same or better than the Lion…

But why use lead acid over Lion?

What about a couple of car batteries?
Like a couple of 895's
7kg each. 12v, 26ah, 200 cranking amps.

I've got a small trailer for this bike, if it has 2 of these batteries in, i presume it would add quite a distance to the standard batteries.

Voltage is as voltage does. The chap I bought my ped from had gutted a GPZ600 and converted it to electric with 10 x 12v lead acids wired in a bank of 2 x 5 to power a 60V motor. Reckoned it was a bit of a bus, but worked fine.

[EDIT]
Standard lead-acids aren't supposed to like being deep-discharged. I haven't verified that, but I'd be vaguely minded to go with those "cyclic" batteries or something similar.

Hi

If weight is a non issue (and assuming no charging issues from using a lead acid battery rather than a lion one) but you still want 24V, how about a truck battery?

All the best

That would be proper heavy, I thought truck batteries were just 12v used in pairs.

20kg wouldn't likely be so bad.

I just want a range of 100 miles, unlikely i'll ever want or do more miles than that on it.

A real 100 miles (up hill and down dale rather than on some Californian billiard table) is really pushing it for electric, even for commercial lithium trinkets.

GPZ600 chap reckoned he got a real 40 miles out of his, and that was mostly batteries.

When you say "bike"...

I'm talking cycle,

Real world reviews from real people of which their are many say 30 miles on the 24v 8h battery that comes with it.


I'm thinking 2x 12v 26ah should, even with a trailer and added weight get the extra 70 miles,

It is electric assisted rather than sit back and press a button, the crank has a mechanism that powers the hub once the rider is actually putting in some effort.

You wont have a problem, youll only get 150 cycles out of those sla batteries though. And dont use the lithium charger for the lead acid batteries.
