All About E-Bike Battery's
The battery’s on the pedal Assist bikes we carry are mounted to the down tube on the bike , this keeps the center of weight low on the bike and close to the motor so the connections between the two are short and clean , the battery’s are locked on with a key lock and can be removed quickly .
The Powerpack’s are 400 – 500 watt Lithium-ion battery’s , a life span of around 1000 charge cycles before they start to hold less of a charge , Life of the battery depends on how you use it and care for it . You may charge the battery at any time, the battery’s do not suffer from any memory effect .
Do not store battery’s in excessively hot or cold environments , hot environments over 140 degrees F will damage the battery , cold environments will shorten the distance you get out charge in the battery ( but not hurt or damage the battery itself )
For Long term storage of battery’s Shimano recommends a 70 percent charge and charge twice a year, Bosch recommends a 40-60 percent charge on theirs for long term storage
Bosch has cold weather covers to help the battery’s run time in winter use , we strongly recommend them .
These powerpacks and chargers are engineered to very high standards, both Bosch and Shimano have met all existing electrical standards so that the product is safe and reliable , the manufacture of batteries is not well regulated in many countries, beware of knock off or imitation products that could have a “Samsung moment “ , in addition some knock off batteries packs can damage the motor and controller systems or trigger error codes , both Bosch & Shimano say the moment you plug in a imitation battery all warranties are void .

You charge the system with a charger (included with the bike) that plugs in to standard outlet , on the Shimano system you have to take the battery off to charge it, on the Bosch system you can plug in the battery either on or off the bike ( seen off the bike above ) .
Charge time for a full charge is about 3 -5 hours depending on system and thanks to the calculations of a local electrical engineer it is approximately 4 cents for a full charge on the Palouse.
it is not a good idea to leave a battery plugged in to the charger for weeks on end, the battery will reach full charge and the charger will shut off , then as the battery discharges a bit the charger will kick back on and charge it up again , this will prematurely wear the battery out .
The range on a full charge depends on the size of the battery and system, what assist modes you use, pedaling speed, rolling resistance of tires, and the terrain, on low level of assist the Shimano is about 65 miles and the Bosch is about 100 miles at optimum conditions , the head units on both give a running estimation of the range in the battery while riding .
Example, Sean Ellis who works here, often rides his Bosch equipped E-bike from his home in Lewiston , this is a 37 mile commute with 3000 feet of climbing , if he uses the Eco mode of assist he still has about a 1/3 of a charge left in his battery when he gets to work, if he uses Turbo mode he will run out of battery about Uniontown , in which case he often has a second battery that he will swap out , so he can get to work fast .
The battery systems have a 2 year warranty on them , we have all the diagnostic equipment for both Bosch and Shimano , we can update firmware and run diagnostics , if you buy the system from us we take care of any issues with the system and work with the manufactures on your behalf in the rare case something should happen while your system is under warranty.
