izip 24v replacememt

[Sevenhills]

Hi

Winter is coming, so I want a new battery for my 24v izip.

I dont want too much diy, and would prefer to use the old battery case. I have noticed some screws holding the battery case together. Is it just a matter of changing the internal parts? I can assemble different parts, its just fitting it to the existing rack that I dont understand.

I am thinking its going to cost £200+ ??

I do have a local Maplins, can all the parts be bought there?

It's just changing the two internal SLA batteries but only if yours uses that type, keeping the connections the same. There are various Izips so I can't say what batteries it has, but you need to use the three dimensions of a battery in millimetres to choose the replacements which should be the same capacity in Ah. They need to be the right type, capable of deep discharge, so I couldn't always recommend the Maplin ones without much more information on them.

Some of the suppliers in the posts linked to below can fix you up for well under £200, maybe half that if SLA. If yours is a more expensive lithium battery model with a single battery in the case, that will cost much more, but I doubt it is:

Hi

Taken my battery appart to find the two lead acid batteries inside; might be quite simple just to replace these.

Maplins appear to have some 12v batteries that look similar, from 7.2AH to 12AH, I assume that the AH is better the higher it is(if if fits inside the case).

Just had a look at the battery connectors. They appear to be soldered on, anyone else found this?

Hi

The 12v battery in Maplins is 7.2 ah (£33x2), the original batteries that are inside the casing are 10ah. Does this mean they are poorer quality and I should not buy these?

Hi Sevenhills.

If you find a good source for 10Ah or 12Ah batteries that fit the currie-battery-box please let us know.

I have only looked a bit, not that urgent yet.

There is a message on the board somewhere about someone replacing the existing batteries with new ones. I just found ti with search, but the link h provided does not do those batteries anymore. :-(

This manual is a bit outdated, but gives a good impression of how to change the batteries: www.electrodrive.co.uk/battery/nixx_pack_fit.pdf

Cheers.

Electrodrive can normally replace those original batteries. As said in my earlier post, I doubt those Maplin ones are suitable. The connectors are "Faston" tags, a type of blade connector that uses push on connections. Those are not suitable for carrying high current, so it's doubtful those batteries could deliver enough for the motor. The right high current connectors are normally thick and used with bolted on cable terminations.

The Ah rating like 7.2 or 10 does not indicate quality, any one can be just as good as another. All it affects is range, think of an Ampere/Hours (Ah) as being like gallons, a car with a full 10 gallon tank will go further than the same car with a full 7 gallon tank.

Hi

When I opened up the 24v case, it was wet inside, I initially thought it was just wet - but I now think it was eletrolyte from the battery itself. So I am still thinking about replacing with 2x12v batteries, maybe 7.2ah will be better than what I have?

That's probably just water leakage into there or condensation Sevenhills. These SLA batteries use a paste electrolyte, no runny liquid, which is why they can be used any way up.

I can't say whether the 7.2 Ah ones will be better without knowing how far your present batteries carry you. If the present ones take you 10 miles or more on the Currie motor, they are ok as they are.

Hi all - I am a Battery Seller and supply SLA batteries for elecric bikes. There are a few mis-conceptions. First of all the batteries on all bikes that take SLA (sealed Lead Acid) type are INDUSTRY STANDARD dimensions. The people who make your bike do not manufacture batteries, they use standard SLA types usually 7AH (same as 7.2AH) 10AH and 12Ah (15AH if they are chinese batteries). You can replace the batteries in the canister yourself and save yourself a fortune...we sell loads of them. All you need is a little DIY skill and remember to connect the terminal cables on the same terminals you removed them from. Also, FASTON terminals are Standard for all of the batteries I have mentioned - bolt thru terminal posts are not standard until you reach 18Ah batteries (as one poster stated).Also, Batteries do NOT push amps into your bike - your bike motor TAKES OUT of the battery what it needs, so the wrong battery Amp/Hour rating will not damage your bike moto. Take a look at our ebay shop: Lucas Batteries Online items - Get great deals on MOBILITY BATTERIES, ELECTRIC BIKE BATTERIES items on eBay.co.uk Shops! And look under Electric bike batteries - I'm not suggesting you buy from us - just remember all the SLA batteries used in bikes are STANDARD sizes and used in many other applications. NOTE: I am only refering to SLA SLC batterie NOT Lithium - that's a whole different story.
