hello again its been awhile since i updated my projects so here's another update =
a nice pic of mine an my missus bike waiting for us while we got a takeaway lol (with my old battery an controller in the frame bag)
i had to move the controller as the bag couldnt handle the size an weight of both the batt an controller
then i spent some money on lipos an chargers etc ( and found out my controller had a high voltage cutoff so i had to get a 48v controller ... so i swapped my 36v controller with a friend for his 48v one )
the initial charge setup (straight from a car battery i have spare)
an i added a charger to keep the car battery topped up ( basically using the battery as a buffer)
i bought an old ammo box from ebay an used that for more safety ( i dont charge with the charger on top obv lol )
i got an ibera bag to fit the lipo battery an moved the controller ( the controller has been moved many times trying to find somewhere good lol)
the inside of the bag showing battery , cables an wattmeter
the battery an connections with watt meter
the much needed brake upgrades ( shimano 180mm front an 160mm rear hydro brakes )
since my gear shifters where part of my original brake i chopped the lever off an moved it over for when i need to change gear... ive always ridden in top gear on the rear so only need the front changer
i put the watt meter into a tin an mounted it with the controller closer to the headset as i was occasionally hitting it with my knees while pedaling
an the inside of the tin
the battery pack wrapped in fireproof fabric an reinforced with plastic sheets an lots of gaffa tape lol
i also added a 120 amp switch with key to save some connectors from spark ( i need to get round to adding a pre spark ) an moved the tin an controller further up the frame towards the headset so i didn't hit my knees again lol
an the wattmeter an switch
the fun i had after months of riding in the rain an the water finnally made its way through my covers ( the bike just lost power on the last road home luckily it was on flat an i didnt have many cars around)
the underside of my controller with some water marks ... luckily after drying an cleaning everything its still working fine but took me hours to strip , clean an rebuild
an a few pics from my wattmeter showing the power increase's from the old battery to lipo an then when i repaired from water damage i may have added some extra solder lol =
the old 36v 6.6ah battery ( it was ment to be a 10ah but i found out its actually a 6.6ah due to chinese false advertisement an only had less than 4ah left after 3 years of abuse)
then the 12s 10ah lipo battery ( it had only done a trip to work normally use 4ish ah to an from work its about 5 miles with a few hills the 36v one used 3.5ish normally so not bad for the power increase)
then after id repaired the controller from some light water damage an added some solder here an there ( after a to an from work 4.3ah instead of the 4ish from before and again not bad for power increase)
ive been keeping an eye on temperature an cables an i may need to re-adjust as we get into summer but currently it doesnt get hot only warm and not very warm compared to my scooter 1400w scooter plaything lol
an ill be looking at getting some more lipo's to parallel so i dont have as much voltage sag an building my own frame box...im off this week to copy my torque arms so my missus has some extra strength as she's ridden my bike an liked the extra oomph compared to her 500w controller ( even tho her kit had the same motor size as mine lol but the controller only gives 12amp an is currently limited by a 7amp trip switch until i made some torque arms lol she was happy with the 300w untill she tried mine a few times lmao
