Chargers

Here you can find the most reliable chargers compatible with most of ebikes running on 48V or 52V batteries.

You can extend the range of your existing battery on almost ANY ebike 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.

The DATE BCx3 600W really helps charing your both batteries or larger battery capcity faster, for example the DATE Bx5 34Ah MAMMOTH battery can be charged in just ~4 hours at 10A while it takes around 18 hours to charge at 2A!

The DATE BCx4 1200W redues that even further to about 2.5 hours!

Important tip!

When charging a battery, the rule of thumb is that the battery should be charged at a slow speed overnight and at a maximum "speed" of <= 0.5C.
The C rating means the capacity of a single cell for example the DATE Bx1 and DATE Bx2 are using 18650 grade A genuine LG MJ1 cells with a capacity of 3500mAh and have 5 in parallel groups.
That means the charger should never charge faster than 3.5A * 5 / 2 = 17.5A= 8A.

Applying the same math for the DATE Bx4 which is using genuine 21700 TESLA cells with a nominal capacity of 4800mAh and 4 cells in parallel groups => 4.8A * 4 / 2 ~= 10A max charging limt.

For the DATE Bx5 MAMMOTH battery the same rule applies resulting to 4.8A * 7 / 2 ~= 16A. The TESLA cells limit is actually 1C rated by the manufacturer which also means that 20A will be just fine, way under the 34A max limit!

Important tip! The RCA and the 3 pin plugs are limited to 8A, so never push 10A when charging through them!

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 and schedule it to start the charger 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!

Tip! When range is not as important you can choose to charge the battery to 90% or even 80% and this will extend the number of battery life-cycles (the number of full charges you can do on the battery) from about 300-500 to 600-800 while still maintaining at least 80% of the original capacity!
