80v echainsaw battery - Sanyo cells

So I was curious what was in my 80v 2ah chainsaw battery, popped it open to find 20x sanyo UR18650RX.

These cells are 2000mah - 20a continuous discharge. So should be decent for an eboard, and the price is also good if I can find a way to utilise the BMS and charger when i change it to 10s2p.

The chainsaw is from a hardware store called Masters (in Australia) who is going out of business and this Kobalt brand of 80v products is being heavily discounted. I picked up the chainsaw with 80v battery and charger for $235 ($175US) and you can get the batteries seperate for $95 ($71usd). Works out to $3.55US a cell.

My other thought is to cannibalize the whole thing and make an 80v board with about 5km range.


That’s putting skin into the game … Good luck :+1:t2:

I want to see this 80v board, and please tell me you can use a section of the cutting chain as a drive chain.

Yeah I’m just about to take the chainsaw apart to see what motor I have to deal with. I did have the idea to use the chain but I don’t think the blades are a good idea so close to my feet.

but you’re going to need them to process the squirrel meat so that the motors can properly digest it.

@Heavy1 Bring it in tomorrow night if you can make it?

This might be of some interest to you… http://www.etotheipiplusone.net/?p=3324

Its chunky to say the least. Measuring just the can its about 50mm, the rubber before the gearbox is a cooling fan, the housing around the phase wires is plastic and adds another 20mm. Im estimating the can around 70mm diameter.

You so crazy! I love it. Can’t wait to see the Chainskate in action. :imp:

Holy shit…
