Use any battery instead of the original Yamaha battery

Due to the chip shortage, the price is unfortunately higher than normal.

As with other brands, the Yamaha PW-X2 / PW-SE doesn't allow to use any 3e party battery. But with the use of the dongle described here, the Yamaha ebike will be hacked so that you can use any battery instead of the original expensive Yamaha battery.

Why did I make it?

On my solarbike, the Maxun One, I want to use a Yamaha PW-X2 mid-drive motor. The problem is that the Yamaha battery is not suitable for my solar bike because:

The PV panels can charge the battery with a current as high as 8A. Normal Li-ion e-bike batteries can’t stand this high charge current. I need LiFePO4 battery cells.
The battery must allow simultaneously charging and discharging, this isn’t possible with the Yamaha battery.

What makes it special?

You can use any battery on your Yamaha ebike instead of an expensive original Yamaha battery.
The battery capacity is measured very accurately with an LTC2944 fuel gauge IC, not just simple voltage measuring.
The battery capacity is stored in an EEPROM so that it is not lost when switched off.

Yamaha battery dongle

Hello good morning
This is the second dongle I have purchased.
Today I received it, by the way very fast
The first one took a long time to assemble, but it works perfectly
I note that this second dongle is different
Well I would like to thank you for the effort made to develop and build this marvel
I feel envy for not having your knowledge
Thank you so much
