[Gens Ace battery]

Hi

Anybody know where can I buy the original PANASONIC 26V battery and BOSCH 36V battery ? the used one is OK if anybody want to sell...

We are interested to research theirs battery.

Thanks in advance.

So that you can copy them I guess...German eBay

Yes, we can... but we do not have the battery case. theirs frame has the patent. you know that...
If we build the shrink battery pack which can fit the original case and can work your bike perfectly, do you have any interest to take ?

It is just an idea...

Thanks

Mmmm..........maybe but I won't be needing one for a few years yet. Would you use identical cells? I haven't even looked at mine to see how easy they are to crack open

Panasonic batteries can be picked up reasonably in Germany anyway and most would prefer the real thing I would think.

heheh.... I understand. As I said it was just my idea. if we plan to do that, we will use our flat lithium polymer cells. BOSCH and Panasonic battery case is square shape. It is suitable for our polymer cells.

I learned they have 2 kinds of battery system 26V (25.2V） and 36V... is these 2 type batteries going with the same size battery case ?

Thanks

Not a clue..

Just out of interest do you know what cells Bosch use?

we just know they are using the cylindrical 18650 cells, but do not know which brand cells they are using...
Someone said it is Sanyo...but can not sure,... and+they marked " made in Poland " on the battery case... I seems that you know them... share with us.... come on...!

Thanks

Hi Benson...we have 2 ex demo 8Ah 26v Genuine Panasonic Batteries for sale....both are 2010 issue,but are still showing full health on the battery indicator (long press of button)-They are a bit tatty but in one piece....alternatively we have 2 Brand new 8Ah 26v Batteries if you'd rather ....

THe Panasomic battery is sold by agents of the bikes using their unit, for example, 50cycles offer them as well as the BMZ-Kaklkhoff alternatives. The Panasonic 26 volt one is on this link at £403.

Other sources are agents for the Spanish BH range and agents for the Swiss BikeTec Flyer range, both brands using the original Panasonic batteries. Here's photos if the innards and base with connection details of that 26 volt 10 Ah Panasonic battery:

1) Charge monitoring, presumably by temperature.

2) Negative (-)

3) Battery Meter.

4) Charging Positive (+)

5) Output Positive (+)

Bosch label:

Li-ion 10INR 18/65 - 4
36V 8.0 Ah 288 Wh
Made in Poland


new 11Ah battery now out, slightly bigger case, fits same bike holder, and I would think most looking for a replacement/second battery would prefer that option

 

[tillson]

I think that the OP isn't looking for a new battery. He is after an old knackerd one for little outlay so that he can work out a way of copying the case and filling it with cells from an alternative source. Maybe this could be beneficial to us all if someone could help him out?

I'd let him have my 4 1/2 year old Panasonic battery, but it still shows full capacity and easily gives me 40 miles range.

 

[eddieo]

yes lots of used panasonics around and even the Bosch turn up second hand on ebay..but rarely

But OP is a company not a private individual so surely can afford new if necessary, can always sell it on (sell, get it? i'm such a card...)

Hi Flecc,

Thanks for your detailed information. The Panasonic new 36V battery are also using the polymer cells ? and 26V and 36V battery shared the same size battery case ?

How about the kalkhoff panasonic batteries ? also the same size with the original one ?
I am surprised that they can make it more than double capacity to 26V 18Ah.
It seems that the internal size is enough,even can be spare for the original 26V 8Ah battery.

Thanks
Benson

 

[martin@onbike]

New 26v 8Ah Panasonic batteries use a slimmer case than previously...(flatter back section)
Old 26v 8Ah use the same as New 36v 8Ah cases...
I think the New 36v 12Ah Panasonics use a similar size to Derby cycles 26v 18Ah cases(much bigger-and heavier obviously)

 

[eddieo]

There is a thread running on German pedelec at the moment that has all the info you will need regards Bosch battery complete with internal photos etc... The works!


It's a long thread and our German compatriots are well ahead of you, so you had better get your finger out!lol

I'm afraid I don't know the answer on the Panasonic 36 volt battery details.

I think all the the BMZ-Kalkhoff batteries use arrays of 18650 cells like those in the 36 volt 15 Ah internals below, this one being for the Kalkhoff Impulse motor unit (click image to enlarge):

We have spare Panasonic 26v 8aH batteries going cheap here for you to sabotage
Got a couple left brand new.

The 36 volt 14Ah Panasonic batteries have a four-pole connection - unlike the 24 volt version in your pic which has 5 poles. Looking down on the side of the battery with the LEDs and the handle at the top, the left pole is indicated as being '+' (call that pole 1) and pole 3 is '-'. The other two poles are unlabelled and I suspect the significant difference from your pic is that there are no longer two positive poles - I believe the charging and output poles are now combined.

It appears that apart from that the connections correspond to yours, though I'm only guessing. Your pic looks as though it's been taken with the battery lying on its side (with the LEDs and handle on the bottom).

[flecc]

That's correct Rog, battery on it's LED and label face. They may have used a common positive, but that doesn't fit well with using a BMS for the charge control. An alternative is that they've done away with the monitoring connection on the 36 volt version, perhaps feeling it not as necessary with the much higher 504 Wh capacity. The original 26 volt battery only had 208 Wh (8 Ah) so could conceivably be more subject to stress.
