Oz-Ebikes BALANCER. We now have in stock a cell balancer that is used to balance the cells in your large LiPO battery packs. This is a must for good maintenance, sometimes it can take 2 days to balance a large 12-20Ah pack properly, as you can be burning off anything from 2-10 amps if you have let your cells get badly out of balance. Out of balance cells are at high risk of death, the low cell/s will die if you discharge the pack too far, the good cells will artificially hold the voltage above cutoff, causing the low cells to overdischarge and fail.

 

I recommend anyone using bigger than 12Ah to have a balancer, it’s a small price to pay for added safety and battery life. Your balance lead simply plugs into the side of the balancer, you then set the low voltage point for balancing, and hit start, we recommend you keep the balancer upright with the bottom facing a small fan or out in the breeze where it can cool down, balancing batteries causes a large heat buildup in the balancer as it has to burn the power off using resistor banks.

SPECIAL CLEARANCE ON HEATSINKS. FULL CIRCULAR HEATSINK WITHOUT ANY CUTS, SPECIAL AT $70.00 UNTIL SOLD OUT!!

I have designed a heat sink to suit the HEADLINE series of motors that helps greatly with motor temperatures, the bane of all electric setups. There have been attempts in the past to make heat sinks for these motors but most of them are flawed in their design and fitment.

 

First thing, the motor housing is not a barrel! It has a taper, cast this way so it can be removed from the mold. Clamping a solid machined heat sink onto a tapered motor housing is not very effective from a contact point. The taper is quite substantial, over 1mm from outer to inner edge. So what we do is machine all our 500w motor cases as they come in, so that they are ready to accept the new heat sink. We can also machine your existing motor if you want to purchase one of these new heat sinks, simply send us the motor & gearbox assembly. You can of course have the motor case skimmed down by any local machine shop with a decent sized lathe. Diameter is critical and must be within 0.1mm of our spec.

 

Secondly, heat sink design is quite important. Radial fins obviously maximise the airflow coming from the front of the bike, the ratio of fin thickness and fin gap is very important as is the thickness of the fin base. Machining the fins crosswise to turn them into pegs is not as efficient a heatsink, reading the engineering papers on heat sinks shows that the solid fin is more efficient at removing heat.

 

Our heat sink is a press fit, it simply taps on with a rubber mallet. We recommend using a tiny film of heat sink paste inside the sink before fitting it but the fit is so good most of the paste will be pushed out.

 

SPECIAL CLEARANCE ON HEATSINKS. FULL CIRCULAR HEATSINK WITHOUT CUTS, SPECIAL AT $70.00 UNTIL SOLD OUT!!

 

AUD$140.00

(this price includes motor machining)

 

This heatsink is custom designed to fit the HEADLINE series of motors, these motors are used by us in our 200-500w kits and also used by Cyclone bikes and many other ebike kit sellers. The motor requires simple machining to remove the taper on the main body, we can do this as a service for $33.00, simply send your motor and gearbox assembly to us.
