Thanks to the originator of this forum Series! I have just converted my Kids 24V OSET 16 to LiPo with great success. I definately encourage the undecided to "take the plunge" it really makes the little Bike. In the end I went for a 7S 2P (two 5800mAH 7S Batteries paralleled) configuration. Last waay longer than the factory lead-acids.... For safety reasons (charging well away from the petrol tanks of diverse MX Bikes!) and because I have two sets and so swap anyway I remove the batteries to charge. The 7S configuration was chosen to give the Bike a little more top-end grunt (both my kids ride MX too so they lap up the power). The end-result is hard to measure objectively but according to the kids it worked. "Much better Daddy!". 7S cells also seemed to me likely to be a better match to tvoltages I measured at which the throttle indicator leds were "counting down". As it is telling the kids "Once you see only 1 red dot its time to swap, low battery dot means - swap NOW" is giving nice conservative battery cell voltages around 3.2 with the battery drained to around 10-20% rated capacity according to the charger. Just to be safe I've put those cheap little LiPo "beeper" monitors you can get on ebay on the balance cables to watch for individual cells dropping too far. So far (20ish charge cycles)... not a peep! There was one self-inflicted negative I like to share though. One of my shiny new batteries had a bad cell. My charger started warning me about it from the from the 2nd charge onwards - warning messages and needing several retriesto get started charging. Unfortunately, I assumed I'd discharged too deeply overall and didn't check the error code in the manual. Needless to say the battery gave up the ghost completely 3rd or 4th charge. Alas, by that time the 30day warranty had expired.... Doh! Lesson: if your charger starts grumbling with a new battery - trust it, discharge for shipping, and send the damn thing back right away.
