If you are considering about creating an electric bike you will certainly have to have a battery pack. Quite a few folks get confused when they began buying for batteries due to the fact there are so several different types and numerous specifications for every brand of battery. Hopefully I can assist clear up some of the mystery for you to make you selection simpler.
The very first issue to look at is what voltage battery pack you require. The best speed of your bike depends straight on the voltage of the battery pack, the higher the voltage the faster the bike. If you want a motor just to assist you even though you pedal your bike continuously you will possibly only want a 36 to 48 volt battery pack. On the other hand if you want to use the bike far more like a motorcycle and cruise about at higher-speed devoid of pedaling a thing in the 72 to 100 volt category would present considerably improved performance. You also need to make certain your motor and controller are rated for the voltage of battery pack you are using.
Subsequent point to take into consideration is the battery capacity which is how long a battery will last on a single charge. It is measured by how lots of amp-hours (Ah) it can discharge ahead of it is empty. If a battery can discharge 1 amp constantly for 1 hour it has a capacity of 1 Ah. The more Ah of capacity a battery has the larger its physical size will be if you are comparing the identical chemistries. A 10Ah battery will be twice the size of a 5Ah battery if they are the exact same sort and be in a position to get your bike twice as far if riding at the identical speed. Many batteries can be connected in parallel (all the constructive terminals connected with each other and all the damaging terminals connected with each other) to enhance the capacity or Ah to your desired level.
Last factor to consider is ‘C’ rating or discharge price of the battery. The ‘C’ rating of a battery is a quantity that represents the safe continuous discharge price (in amps) of the cell. A battery rated at 1C can discharge its rated Ah capacity in current without the need of harm. A 2C rated battery can put out twice the number of its Ah rating in amps. If bosch fiets accu is rated at 1C, its maximum secure discharge price is 10 amps, if the same 10Ah battery has a rating of 3C, it can safely discharge 30 amps. Likewise if that 10Ah battery is rated at.5C it can only place out five amps safely.
Hope this assists clear up some of the mystery of what to appear for when shopping for batteries for your electric bike.
