Re-celling

[mike killay]

It occurs to me that there are now quite a lot of batteries out there made up of small cells.
Not only on e-bikes, but other devices.
When it comes to our needs, the cost of a OEM replacement is often high, yet the radio control people seem to handle all these different things easily.
Are then any domestic firms offering re-celling?
These would be particularly useful for bikes where the manufacturer has gone, or those 'in frame' batteries which are an odd shape.

I don't think that anybody would get liability insurance for that. There's nothing to stop anyone sticking their own rc lipos in the case.

There's any number of people re-building batteries.

Mostly specialising in power tools, but some will do bespoke jobs.
It's not rocket science and obviously their insurance companies don't have an issue with it.
(I presume they are insured).

Scimitar, d8veh is talking about re-celling with LiPo batteries such as Hobby King ones, I doubt as d8veh said anyone would be doing so commercially due to their needing careful feeding and treatment to prevent a F&S incident mind you they do perform superbly.

The Electric Transport Shop is the only electric bike business that I know of who offer this service.

I don't know if they do this 'in house' or outsource the work.

Here is a link to their website Electric Bike Sales - Shop Online for Electric Bikes, Electric Vehicles and Cycle Accessories - Battery Repair or Replacement

It is not cheap and in many cases could be cheaper to buy new.

Ouch, good reason to learn DIY plus the care and feeding of LiPo, Hobby king 36v 10amp 20c around $150 aud plus shipping. Roughly 84 pound.

If your battery is not LiFePo4, you could re-use the BMS, to make your lipos plug-and-play because the cells work at the same voltage as the standard LiMnCo. Re-celling with 18650 cells is also fairly straight-forward, as most batteries are changing over to them. You can buy the cells welded into a suitable configuration. The only skills you need is to be able to solder, operate a voltmeter and work a screwdriver.
