I used then for the alarm. the alarm triggered a relay to shut off the charger or cut discharge at LVC

Hi guy's what are you guy's using as a replacement to the discontinued hobby king cell-log's. A link would be appreciated

Not at -30 c

Hey Trapper, I totaly agree nicd very stable if treated right. Nothing beats nicd for winter rideing at the temps we get here in Canada !

Me and others noticed last winter that we lost YW batt capacity when it got colder. Is anyone using anything other than YW chargers to charge ? Looking for a 3 packs in series charger, any suggestions ?

My chargers also whine I think its just the break down of insulation on the coil giving the high frequency sound. NV Did you make any progress repairing/modding your dead charger ? My dead charger was just the large on board diode at the output dead, probably caused by me forgetting to throwing...

hi all I had a charger failure also, It was the one of my chargers with the two chips, I think the same as all your's NutsandVolts Not one of my seven YW packs (one spare) is original as they have all failed within the year, luckily I purchased mine online, which comes with otc replacement or...

I had a similar strange very loud knocking noise almost like someone was hitting the motor with a hammer on clite 408 and the problem turned out to be an intermittent bad connection on the hall sensors this would also explain intermittently no response from throttle or just a grinding sound...

for anyone interested it cost $30 for a straight swap of axles 5 minuetes or $120 installed for a new machined hardened steel axle 4 hours I went for the hardened steel no point putting that crappy china steel in again.

Hi all, Anyone around Toronto got access to a ten+ ton hydraulic press and would be willing to swap out a 400 series axle. Has anyone here done this before ? If so any tips ?

Hi Mike welcome back I returned all my 6 YW packs and got refunded and purchased 6 more online for a new 1 year warranty. To get refund instead of replacement (which doesn't extend warranty) you have to make sure the store you return to doesn't have them in stock. When you return no ID is...

The ebike switch brake levers (which aren't reliable) will not take the volts/amps guess you could use them to activate a relay, you need something pretty hefty as a switch, the back EMF can be higher than the input power. I used a dpdt 125v/20A (used what i already had) and paralleled the...

The resistive breaking using the wasted back EMF to heat the battery packs works great. I used a 25 foot coil on a piece of flat bar which I place under the pack bag. It keeps the batts at room temp with riding temp around zero and wind chill -7. when it gets colder i will probably place the...

Nuts and volts, After seeing your original post I also repackaged my 3 chargers which i have on a relay with timers to charge the six packs i have, takes longer to charge but i only overnight charge. I think i'm going to try the resistive braking using the rectifier.This will be on a clite 406...

Nuts and volts are you still using the YW chargers and BMS ? How balanced are the cells after the 300 cycle mark ? I've noticed the YW chargers are a little sensitive and sometimes they will terminate a charge cycle and show a pack as fully charged even though it is nowhere near full if there...
