I've come to the conclusion the Eco-Worthy battery won't be fit for purpose. If the 800w motor is 36v that means a peak discharge of 22.2A would be needed. The Eco-Friendly battery is rated at 10A discharge. I'm now investigating batterys on AliExpress. This battery AERDU 36V 11.6Ah 10S4P 18650 Lithium battery pack for 36V batter 250W-750w ebike electric car bicycle motor scooter with 25A BMS looks like it maybe fit for purpose at

Hi, I'm currently going down this journey and was wondering what Wh or peak discharge current I should be looking at for an Oset 16? It is 36v. I found a Eco-Worthy LiFePO4 12v 10Ah battery that is relatively cheap and has a BMS built into it. Should I look at batteries like this or stick to hobbyking? I'm limited in choice due to being in Australia. Thanks

Thanks but we are just talking about $135 (Century Lead Acid) vs $189 (Eco-Worthy Lithium) so the boys can get at least another hour out of the bike. The concern at this stage is more around the $189 lithium battery. For example if it has the power and is built to a high enough quality for the bike.

I've been researching various lithium (LiPo4) battery solutions for the Oset 16. A cheap alternative I found has been this Eco-Worthy brand which are 12v 10Ah. They are the same size as the stock batteries so I will wire in series to get 36v 10Ah. - On the Eco-Worthy datasheet, what values should I be looking at to ensure the Oset can draw the power required from the batteries? Looking at a total of $189 plus a charger. - Can I use the standard Oset charger designed for lead acid on the Eco-Worthy lithium as it has a BMS installed? This is the data sheet on the Century PS 12100 lead acid battery I'm also considering which is very similar to the stock battery. Looking at a total of $135 The Milwaukee battery packs for 2 x 18v 8Ah is $400 plus the cost of the adaptors. Thoughts? What option did you go with? I'm located in Australia so I have seen some better options available in the UK and US on this forum. Thanks

Hi, I just purchased my first trials bike (2013 Beta Evo) and starting my journey in trials. I'm trying to teach myself about the mechanics of the bike so I can personally take the best care of it. Upon purchasing the bike the idle was a bit rough. The sound of the bike would fire and give a slight jolt to the bike. The owner said the bike had been sitting a while so the carburetor most likely needed a clean. I poured the petrol out that was in it and added 98 octane unleaded mixed with Castrol Power 1 TTS racing 2T (70:1 ratio or 71ml to 5L) & Liqui Moly carburetor and valve cleaner (20ml). As described in the owners manual - EVO 250/300 2T MY13 [2013] I adjusted the idle speed which improved the performance and the jolt I was feeling before. I went to check the Air. The manual states to "From all closed recommend to 11/2 turns" From reading posts on this forum it appears that needs to be 1 to 2 turns with most people set it at 1 1/2 turns. The bad news is I could not find this valve or the screw to adjust the mixture at idling. Any recommendations on what to look for? Here is a video of what the bike sounds like after the idle speed adjustment. See how there is a bit of shaking at the back of the bike? Is that normal? My next issue is that the fuel take valve doesn't shut off petrol. I thought the 20+ seconds would be enough for the engine to die. Thanks
