If you are considering building an electric bike you will obviously need a battery pack. Lots of folks get confused if they started shopping for batteries as there are many different types and various specifications for each brand of battery. Hopefully I might help clear up some of the puzzle for you to cause you to decision easier.
The first issue to consider is exactly the voltage battery pack you need. The top speed of one’s bike depends on the voltage of the battery pack, the higher the voltage the faster the bike. If you’d like a engine just to help you as you pedal the bike continuously you’ll probably just require a 36 to 48 volt battery package. Alternatively if you want to utilize the bicycle just like a motorcycle and cruise around at high time minus pedalling some thing at the 72 to 100 volt category would provide far better performance. You also have to ensure that your motor and controller are rated to the voltage of the battery package you’re utilizing.
The next issue to consider is the battery capacity that’s the length of time a battery will last on a single charge. It is quantified by how many Amphours (Ah) it may discharge before it’s empty. When a battery may discharge 1 amp always for 1 hour it has a capacity of 1 Ah. The further Ah of capacity that a battery has got the larger its bodily size will likely soon be in the event that you are comparing the same chemistries. A 10Ah battery will probably soon be twice the size of a 5Ah battery should they are exactly the identical kind and be able to receive your bike two times as far if riding at exactly the same speed. Numerous batteries can be connected in parallel (all the beneficial terminals connected together and all of the negative terminals connected together) to boost the potential or emphasise to a preferred level.

The first factor to consider is’C’ evaluation or release rate of the battery life. The’C’ rating of a battery will be a number that represents the safe continuous discharge rate (in amps) of this cell. A 2C rated battery can create twice the range of its own insecurities rating in amps. If your 10Ah battery is rated in 1C, its maximum secure release rate is 10 amps, in case the very same 10Ah battery has a score of 3C, it could safely discharge 30 amps. Likewise if that 10Ah battery is rated at.5C then it can just put out 5 amps .
