most other batteries lose a certain amount of charge on a daily basis. lifepo4 and lipo batteries will hold their charge for a very long time .i do about 10 miles every day and charge it every night.If I only do a few miles I wont bother to charge it at all.lifepo4 and lipo`s will give out their charge(power) right untill the controller or the battery management system(bms) cuts out.
theres no need to check the cell voltage(the bms Balanced`s them) unless you think the bike is not doing what it should.
apart from that, the life04 battery are easy to live with.
i use lipo batteries for my rc planes and thrash them all the time.as long as they are kept Balanced charged they have a happy life-lifepo4 are even better to live with than lipo batteries, and are a lot safer,take more charges and live a lot longer.
