Here you can find the most reliable batteries and chargers compatible with most of ebikes.
The in-frame batteries are compatible with all major 20x4 FAT tire foldable bikes such as, but not limited to:

• 𝐃𝐀𝐓𝐄𝐱𝟐
• 𝐃𝐀𝐓𝐄𝐱𝟐𝐖𝐃
• MATE X
• Engwe EP2-Pro
• Engwe Engine Pro
• Engwe C20
• RANDRIDE Hummer
• ...and most of the MATE X-like 20x4 frame clones

Note
All the FIIDO ebikes as well as MATE CITY / MATE S / MATE ICON are using a smaller battery form factor so only the DATE Bx5 would be compatible as a secondary battery.

Important Note
The MATE MONCLER are using the same form factor batteries but different pinout. DO NOT insert a battery that is NOT listed as being compatible with the MONCLER! You can select this option on our in-frame batteries in the page's product option, but it is important to choose accordingly, as otherwise it will fry your controller, display and GPS!

You can extend the range of your existing battery on almost ANY ebike, including FIIDO with the help of the DATE Bx5 MAMMOTH 52V 34Ah 1760Wh regardless of the existing batteries of 48V or 52V bike, and irrelevant of the form factor, shape, capacity etc. via a DATE Dx2 or DATE Dx2C
This will add you a huge extra range so you can enjoy exploring the world and forget about charging the battery issue!

When you want to extend the battery life you should always use a smart, much reliable charger such as the DATE BCx3 600W dual voltage charger which is compatible with both 48V and 52V batteries and allows you to toggle the charge level to 80% 90% or 100% as well as to choose a very slow overnight charging speed of 2A up to 4A fast charge, 6A, 8A and even ultra fast charging 10A.
The 10A is extremly useful when you ride with more than one battery or when you charge a bigger battery via the XT90S plug. The RCA plug and the 3pin plugs are limited to 8A.

Tip!
Choosing to charge your battery slowly at 2A overnight will help the BMS to allow enough time ballancing the cells.
It is recommended to charge the battery at least once per week to 100% at 2A for the ballancing to happen.

Important tip!
When not using the bike e.g. in the winter season or holidays it is recommended to set the charger to 80% and use a smart plug to open it once per week for about half an hour to keep your battery healthy. Doing so it will protect your battery and avoid the scenario where the battery dies saving you hundreds!
