Akku-1
Important:

There are now some instructions in the network for extra battery, but many WRONG or insufficiently documented! If your scooter shuts off, for example, in the CHARING-MODE at standstill after you have installed the battery, the scooter must be switched ON and OFF at each standstill or held on impulse (slight back and forth wobble). In the city traffic at each traffic light more than annoying! This is not the case with our two RollerPlausch instructions, because we hang our batteries BEFORE the battery or fix patch with charging mode. We have already tested these instructions on several scooters and installed batteries and tested them with countless kilometers, everything in perfect order!

Rangetable

This manual is based on our experience with the Xiaomi M365 & the additional batteries, this combination is simple and cheap for an electrician. This achieves range of up to 80 kilometers! (Pay attention to weight & total state)
  • ⚠️The 2 batteries (main & additional battery) are charged together, after the first time both batteries have been charged separately from each other! After that, both batteries are always connected together and will not be disconnected! ⚠️
  • ⚠️ All work on the battery is carried out under current or residual current. When assembling, pay attention to the polarity reversal and do not cause a short circuit. There is no guarantee or liability for modifications made by this manual. ⚠️
  • ⚠️ Pay special attention that both batteries have the same voltage! A voltage difference over 0.5 Volt can damage your batteries! Never connect an empty battery with a full one! 💣

⚠️ Battery charging ⚠️

There are 4 different ways to charge the scooter with additional battery.

Recommended option 1 - charging time ~ 5.5 hours

Charging via the scooter charging port + charge via extra battery pack of the additional battery at the same time. Relaxation is between 41.5 and 42V (depending on the charger of the additional battery)

Option 2 - Charging time ~ 5.5 hours

Separate load. Disconnect both batteries, charge original battery with original charger. Extra battery with extra battery charger Charge. Measure the voltage (Max + -1) Connect batteries after both are full. Roller charges on 41,5V the additional battery to 42V. After connecting, the voltage equalizes and both are approximately in the middle at 41.75V.

Option 3 - Charging time ~ 11 hours

Load at the scooter loading port. This charges both batteries. The original Xiaomi charger charges both batteries equally to 41.5V.

Option 4 - Charging time ~ 11 hours

Charging via additional battery port. Battery charges to 42V. There are 4 different ways to charge the scooter with additional battery.
