sveson Posted January 6, 2017 Report Share Posted January 6, 2017 I have installed LiPo batteries on an Oset 20.0 48v before with good result. Now its time for my daughters 16.0 but I am not really sure about what batteries to use. I would like to have maybe 12000-16000 mAh and I am thinking about anything from totally 8 cells (29.6v) to 10 cells (37v). Is there anyone here who have done this and what batteries have you used?

scottwitting Posted February 15, 2017 Report Share Posted February 15, 2017 I have run two 36V Osets on Lipos for while now, a 16 and a 20 lite. I use two 5s 8000mAh batteries in series, so 10 cells, 37V nominal. The throttle lights drop from three to two lights at a convenient 37V so you, or the child, know to change batteries then. Bike operates fine with these. Quote Link to comment Share on other sites More sharing options...
brianjonesphoto Posted June 14, 2017 Report Share Posted June 14, 2017 I'm about to do the same thing with my son's 16. I have a couple questions. How much run time do you get from the 8000mah batteries? What C rating did you use? Are you running a bms or just charge when 1 led goes out?Do you charge parallel or series? thanks Quote Link to comment Share on other sites More sharing options...
scottwitting Posted July 10, 2017 Report Share Posted July 10, 2017 Run time obviously depends on type of riding, as a guide I can get my 22kg son on his 16 two thirds of the way round the Sherwood red mountain bike trail before a battery change is required. This is about 5 miles. My understanding of C rating is that you multiply the capacity (8Ah say) by the C rating (15's about the lowest) to give a current that the battery is comfortable being used at. So this gives 120 amps. Given that the Oset 16 is fitted with a 40 amp fuse I reason that the current rating of the battery is never going to be a limiting factor! These batteries are designed to be used in a quadcopter type thing that will drain the battery in minutes, not half an hour like on an Oset. No BMS, just train the child to tell you when a light's gone. I'm not aware of a plug and play BMS that is suitable. Parallel charge. After a ride (down to two lights ~ 37v) I storage charge the batteries if they're not going to be used for a while and then fully charge (balance charge every time) a day or two before riding. I'm no expert but this seems to work and keeps my battery's quite well balanced. Hope this helps, sorry for the delay replying. Quote Link to comment Share on other sites More sharing options...
