last runs blew out the low volt cutoff, so i added a fancy digital VA meter.
here’s the 400 amp shunt added to the pack negative.
and the whole guts on the bench for testing, fancy meter, 400 amp speed controller, 200 amp cutoff solenoid, and even the new throttle control.
fun first, art second, safety third, how about 250 amp inline fuse on the fly?
all tucked back into the battery box plenty of room for the charge balancer board and a beer or two.
and then stick it all back on the bike.
nice blue LED display, unless use an ipad to take the pic…
ok, so that was a nice pressure drop, got 2 inches or more of rain here in the first band. yeah, not wave, band. like hurricane’s band up, so did this storm. more coming, stay tuned.

pressure holding steady, sunny HI holding on barely at the coast, still getting a bunch of wood split hoping for a few days of secluded rainy creative and accordion practice.

ok, not really a car, but the whole HookUp Truck show is fo sho ART!!!
support Spy Emerson and support me supporting her!
signs pointing to some rain in the next days, fingers crossed, bellows squeezed….

found someone upgrading their roof solar panels, cash talks and walks.
2 are on the station bank, and the other 2 on the house bank. nice solid 8amps at 45volts or so thru the MPPT controllers for each pair. not bad for “used”….
well, i sent the new ebike pack out, as the new charge balance board was doing ok.
so they ran it hard, i mean really hard, charged it up fine, then ran it even harder still, till the smoke came out. i don’t know if you’ve ever seen lithium battery fires, youtube can show you, these cells have the equivalent of a few dozen laptops together, so the fire hazard was very real.
lucky, it was just the huge cutoff transistors that melted away. they must have not been fully “on” with my tap to the balancer board, as the fuses did not blow rated 250amps.
gonna be hard to remove them from the heat sink.
never seen inside one of these before.
now i know how the terminals work, can see the rest of them still attached to the PCB. i think i’ll do a breaker and shunt instead, a smart display and current monitor, and use the big contactor on the bike as the cutoff.
so looks like the smoke stayed in. all new 14x 48v 40Ah lithium cells, and a new charge balancer board. i couldnt find one that does 250amps, so i put the 50amp board to the charger, and tapped the cuttoff fet gates to the original 250A board to the motor. way more kick in the pants than i am comfortable on 2 wheels with. quantya.
one week left in Taurus, so here’s a report on the greenery.
newest camper (not mine) has doubled size and awareness in 2 weeks, you know how they are at this age, chewin and poopin….
mom and dad have taken to hiding out in the house and garage to get away from the newly fledged kids wont leave them alone, plus it’s warm on foggy days.
these peas are very similar to natives i guess, no bugs chowin on them and soooo sweet too? the experiment of using sunflowers for trellis timing was off, (volunteer too early, purpose too late) but they don’t hate each other so far…
this is one mustard plant. pinched along to maximize seed. fence is 5′ tall.
recycled redwood berry box 2nd version. needing the bird netting now thus the end sticks up.
early box already rotating, more dill and lettuce in the blank where 2 lbs of winter potatoes came out. take that foodco !!!
