I honestly can't believe the run time i get from my recent lipo conversion. We took it bush last weekend and he would have done easily 12km of fire trails over a couple of hours and the battery dropped from 42v to 37v. I'm using 15ah setup and was going to add 2 more batts to make it 20ah but don't think will worry now.

Went for a really good ride with the boys today, bike performed flawlessly and lasted way longer than I expected, still is at around 39V after their riding session. I was contemplating adding another 2 more batts to make it 20AH but don't think I will worry at this stage. One of them had a good stack and broke the seat plastic so think i will just get a local person to knock up a replacement seat with padding more like a normal motorbike.

Thanks for that yet again, I was thinking it could only go down to 37V so a bit more riding time again. Will move the watt meter up on top of the batteries, was just sitting there for the pics. I'm definitely going to need to do something with the throttle, it's snappy as anything now, PITA for turning sharply when you want to go slow

Batteries are all wired up and installed, fully charged they are just over 42V, what is the minimum I can let they get down to before charging? here you can see all the battery XT60 connections and the XT90 connections which I can disconnect to charge each bank of 3 batteries I went a little crazy with retaining them on the bike and used the existing battery bag and also one of the fire blanket charge bags just to protect the little guys a bit.

thanks again

so my batteries and gear finally turned up today, very slow shipping from HK. I'm planning on wiring up as per the diagram you posted Gwhy and split them in 2 x banks of 3 for charging with those X200 AC/DC chargers i previously linked. settings are listed here http://www.imaxrc.com/images/pdf/X200%20ACDC%20manual%20en.pdf Question what settings do i use for charging them like this? Charge Amps? 0-10A Discharge Amps? 0-3A Cut off Low Input? Range of setting:10-24V. Lowest cut off input voltage, charger will stop charging/discharging when input voltage is lower than setting value. Cut off Temperature? Range of setting: 40-80°C. Cut off Temperature, char- ger will stop charging/discharging when temp of batteries is lower than setting value. Cut off Capacity? Range of setting: 0.1Ah-10Ah. Safety capacity. Charger will Stop charging/discharging when capacity of batteries is higher than setting value. Cut off Time? Range of setting: 10-200mins. Safety time, charger will stop charging/discharging, when charging/discharging time is less that setting value. LixxCheckTime? Range of setting: 5-60mins. Time for checking cells count of LiPo battery pack. Waste Time? Spacing interval between 2 Cycles. Range of setting: 1-60mins. Cycle Time? Range of setting: 1-6 times.

no luck with the tamer, he didn't have any left in stock

thanks, i emailed him and he said he didn't make them for Osets, I did order one from that site so will see if it turns up and if it can be made fit

Gwhy, do you still have the contact details for guy who makes throttle tamers for the 36V bikes?

well I decided on a charger, ordered 2 of these today (free shipping deal) http://www.hobbyking.com/hobbyking/store/__53601__HobbyKing_8482_X200_AC_DC_Touch_Screen_Smart_Battery_Charger_10A_6S_US_Plug_.html the built in power supply sold me, will allow a quicker charge time for the 6 batteries than the single 10s charger and simplify without needing a separate power supply. Plan to split the batteries into 2 separate banks of 3P and charge them in a fireproof bag

thanks heaps, much appreciated

I'm struggling with how the running diagram needs to look for 6 x 5s batteries for a 36v system. I thought i needed 2 lots of 3 batteries connected in parallel (all reds connected to each other and all blacks connected to each other) then connected in series (one red on one set connected to one black on the other set) and the remaining red and black leads are the system leads - or is this wrong? if so, appreciate if someone could draw up a pic like mine showing all 6 batteries wired up cheers

have a look at the diagrams i posted previously and the parts i have listed. I've looked at my "running" diagrams a heap of times and think me and GHY have the same layout, just my diagram looks more complicated because it shows all 6 batteries installed. i'l do a full summary in a few days when it all turns up and i get started wiring it.

I edited my post, i understood but didn't explain it well. I just found these 2 chargers which may work well dual 400W (assuming each output is 200W at 10A) http://imaxrc.com/X400%20twins.html and even better same one as I was looking at but built in AC supply which I should be able to run on 240V to remove the need for a separate psu http://imaxrc.com/X200AC-DC.html
