Conversion kit ordered

[Alan Quay]

Yip downtube battery ordered,I was wondering about that very thing but reckoned it must be ok cause haven't seen it mentioned before, shouldn't be a problem though av got access to the proper tools in my work

Sometimes the existing holes are in the right place, and will be OK for light (road) use. In my experience, an extra one is a good idea.

the mid drive central motor ebike kits would be more easy for installation since the controller is inside the motor .

I have the ebc rear hub kit fitted to specialised sirrus elite but used a bigger controller bag (there is a lot of wiring)

as regards downtube batteries its asking a lot for 2 5mm bolts to hold a 7lbs battery in place so I use cable ties in addition to the bottle cage mounts.
I also use cable ties around the frame and battery, (I do not remove battery to charge it)

some people have broken battery mounting plates after hitting potholes etc.

I am at present installing a ebc 250 watt crank drive, but it is not all plain sailing, there is simply no room between installed moter and frame to run the rear deralier cable in its original position (under bottom bracket)

so ive got to somehow re route the cable

ps screwfix sell long /strong cable ties 500mm long if I am correct

Kit arrived today and yes am thinking an extra something to secure the battery is a good idea, I ordered a 13amp downtube battery but the sticker on it says 36v 11000mAh ,is that right or should it be 13v 13000mAh? Here's a picture

36volt 13000mah is what I would expect.
Sale of goods , not as described.
Please send correct battery and collect wrong one or refund

Looking closer at the English,
, desposed to fire?
Alkalesecent liquids?
Translation is not top grade. Is the compliance that good?
Right sticker wrong battery?

I have just looked at my ebc battery nothing on mine to give the ah rating but I have asked and been told 13ah

I have just weighed the ebc one=6.37 lbs
my bottle 10.4= 5.50 lbs
have no idea if that's relevant
I would give them a ring they are very helpfull

Strange that your battery has no markings on it,somebody might know how to check it,it might be as easy as sticking a multi meter on it?

No, the only way to be sure is a full discharge test. You can take it apart and look at the cells, but that's only as good as what's printed on them.

Discharge test can be done on the bench, or on the bike with a watt meter.

Nothing is ever straight forward!

One of these, connect between battery and controller, ride around a bit and it will let you know how much has been used.

Unfortunately, when the battery dies, so does the power supply to the device, so all memory is lost. Either power separately or check regularly.

When I test capacity I do so on the bench, with a fairly constant load.
