So I am almost done building my battery for my tow boogie and now realise the LG M50LT are gonna probably impose some limitations due to the 10 -25C optimal operating range to get the max current draw of 14.4 amps. My pack is 14s8p
I didn’t realise this restriction at the time of planning and to make matters worse I live in NE florida where water temps in summer are around 29C / 85F. Yikes
I know @jkoljo is using them on his efoil and loving them but I think he rides in an area where ambient air and water are nice and mellow and he is also much lighter than I am (190lbs).
I guess my only options are to cut my losses and get the moli p42a’s or find a way to cool the battery compartment to within spec.
I have considered using a peltier connected to a water block on the outside of the case with a pump to dissipate heat quickly to the outside. On the inside a little 5v fan blowing on a coldsink.
Other thoughts are to just run a long coiled copper tube on the inside of case and use passive seawater from the nose cone. Not sure if the copper will be able to remove enough heat out the box this method.
I might also have to place the esc in a different housing separate from the battery which sucks coz I wanted it be AIO.
I am hoping all the brilliant minds on here will help me figure this out somehow.
