wanna use 2 52v batteries!!!

[post911]

okey guys, took out the controller for my dual 1500w brushless motors today from my trike's belly which was indeed painful but can please anybody tell me where i can find a controller which can take 2 52v packs in series and have connectors like this controller has.
currently this controller can take 36 to 52v but the motors on this trike feel like they are not even awake even with 52v pack,
and the last picture where u guys can see the display panel which only has 2 power settings like 10s or 12s which tells me that controller attached to this display is 48v so when i use my luna 52v packs it lets me use it when i set power mode to 12s, but like i said,
so yeah any help is really appreciated.

A controller that produces more amps should do it. Lots of variables to think through before you turn a 52 V system into a 104 V system. Wiring, connectors, motors, controller -- you're basically starting from scratch.

I'm not really sure what you mean by "the motors feel like they are not even awake." Does that mean poor acceleration, top speed isn't fast enough, or ?????

I'm no trike expert, far from it, but my understanding is that they tend to be more on the sedate side. For instance, the Pedego trike has a stated top end of 11 mph, vs. 24 for the City Commuter. It seems they maximize stability and perhaps payload over zippiness.

never mind buddy, i changed my mind, or should i say the new triangle 52v 17.5 ah battery from luna cycle changed my mind about going for 104v...
just tried this battery and i don't understand how this battery can output so much current, given the fact it's a lot bigger in ah but same volts as compared to the mighty mini which was 6ah but i have to agree the bms on mighty mini and bms on this triangle pack is totally different.. i just used this new triangle pack by setting my trike controller amps to 60 amps and boy oh boy... a good battery pack makes a hell of a difference...cheers.

The mighty mini (I have one too) is 28 cells, 14 groups in Series, with two cells in Parallel per group. Battery geeks call that 14S-2P. The new triangle battery has 14 groups in series too, but I would bet it has 5 cells in parallel (14S-5P).

A single cell can put out 10-15A. Crrrent adds in parallel. So the mini might do 20-30A. The triangle can do 50+ A. The BMS can further restrict the current, but not at Luna. They like to let them run wide open.

yes sir, u r absolutely right on all points.
