will this work as is on a 4s pack or will it need to be modified in any way?

nevermind, i found a solution (not sure how i failed to find this before). https://www.instructables.com/id/Make-a-Battery-Protection-Circuit-low-voltage-cut-/

i'm hoping that the alarms can be modified in some way so that instead of making a noise i probably won't hear they cut off the power from the batteries instead. is there perhaps some kind of electronic switch that could be set up to unlatch instead of setting an alarm off?

I thought about posting an instructable but I don't know anything about how to weld or cnc, these were done on my behalf from my doodles. I just did a passable job of sawing and bolting stuff together haha...

i saw bicycles with sidecar cargo platforms and thought i'd try something similar with my board, i plan to have swappable platforms for different loads this one will have a big speaker bolted to it for skate meets/critical mass etc and another one is just going to be a plain cargo rack...

change colour in the same way wood does when it gets wet or darker than that?

oh i intend to charge them with a standard charger, i was just concerned that running a combined 36v through 2 usb adapters that are presumably rated for 18v each might cause problems...

id like to do a scaled down version of this system, would a P-Audio BM2-D750 and one (or two) of these subs (http://store.accusafe.nl/onderdelen/luidsprekers/subwoofer/dayton-audio-sd215a-88-8-dvc-subwoofer-speaker) be compatible with my maxamp20 class D amp (http://store.accusafe.nl/modules/versterkers/maxamp20-met-3-5mm-connector) with an appropriate crossover? how do i choose a crossover, there seems to be a lot of choices on the Blue Aran website much smaller than the chunky looking crossover in your enclosure? what difference would choosing a slightly smaller horn for the driver have on the sound?
