Hi All, I am looking for a new battery after my previous one failed and wanted to ask for a little advice before I order. I have a MXUS XF08C rear wheel motor & am considering a 36V 15Ah battery with Samsung INR21700-50E cells in 3P10S arrangement. The advert suggests a continuous discharge of 25A with max of 50A. The controller is KT 36V 250W 6Mosfets 15A Brushless DC Sine Wave Controller, from the little I know it seems a suitable choice, but wondered if anyone could either help me confirm that, or advise otherwise? I have been trying to find a suitable battery, that will fit within the frame & has branded cells, this seems the best option so far.

Thanks.

The specs are ideal with plenty in reserve so not to stress the cells with high current draw.
If one constantly used the the 15a draw frome the battery via throttle or PAS 5 to 3.2v per cell then one can expect 2.5 hrs run time or approx 12.3ah from the pack as a whole. If one uses low PAS 1 or 2 then one can expect to see 13.2ah or more out of the battery.

Many thanks for the response. I think I will get this one ordered before stock disappears again.
