properly cleaned dried 18650 can cells may survive brief clean fresh water submersion

long term soak depends mineral content and resulting discharge

diy person with meter and basic skills can pinpoint trouble

determine best way to go

for hire service people wisely avoid due to liability risks

6ah mighty mini packs running both hd & 02 here

10-12 miles range w/02

8-10 miles average range w/hd

short 1500w (30a) hd peaks haven't reduced range after year regular use

install enough bb units you run into angles frame tubes won’t allow straight wrench to engage the nut one workaround is to make l shape into wrench so the handle clears frame obstructions if that’s the case here not a very good job of reshaping the wrench but can understand why someone might attempt...

broken welding tab would probably not allow it power system barrel connector charge port is a weak point on these packs op needs dvm (volt meter) to see voltages what where when if can make the wiring connection can often charge through the discharge side of pack bms. but dvm is needed to determine ...

some built that way

20-50ua current quiescent consumption common adds up 24/7

sometimes bleed balance circuit short or turn on and never turn off

if so channel balance resistor will be warm to touch dissipating 50-80ma

always best to unplug bms long term storage

12v house system may also crank genset if equipped

could be tied to chassis cranking batteries like any power gear stuff, jacks, slides, etc

contemplating 48v tesla modules here

be realistic 2 kWh to even think about cruising 50 miles @ 30 mph 36v55ah, 48V42ah, 52v40ah, 72v28ah take your pick but there’s no way around massively heavy/large battery pack bouncing around fat tires = all-terrain cheap suspension for 20-25 mph cruise platforms best try it before you knock it not...

overloading, over-speeding and massively overpowering bicycle components will not end well desired speeds (c30 t45) possible with rc lipo or other high c rate but range will be around 1/8 stated range goal flat level ground no wind cruising 20 mph (500w) requires a fairly massive battery pack to tra...

tire rub repair splice isn’t bad if there’s some wire to work with. yanked out of the controller is very hard to repair mostly due to potting used on controller pcb. i dug out enough to reach solder pads but also broke off important inductor component and pretty much sealed the deal for new controll...

definitely garnered some looks passing by i myself couldn't hear dogs barking or much of anything. timbre of noise/sound changed considerably between asphalt vs concrete vibration throughout the bike felt like an engraver mid drive made quite a difference being easy wheel to remove roadside and stro...

rim hit something and broke chunk from bead.

sharp edges poked tube with 5 miles to go.

removed tire/tube then rode home about 10-12mph.

Okay good info. I have stock programming but I do usually have it in PAS 9 . I didn't expect any damage to come from that. recommend display with watt/amp meter or insert an inline to verify but most pas 7 usually keeps things around 1000W continuous. depends how long, ambient temps and workload bu...

1000's miles on 3qty bbshd's without any hiccups. one unit did begin to make similar noise and went away - never cracked it open. never came back - has bit more side to side play of spindle than other 2 units but otherwise working normally. bbshd is 1000w continuous power rating. pas levels 8 & ...
