Could you please post up the suppliers details?
Supplier/maker of the battery... you can actually make them yourself if you know about wiring battery cells together. Its the Lifepo4 3.2 cells I think he uses. The Battery starts the Hyper fine. I will report longer term as I use the battery.

FAQ
1. Are they Lithium batteries?
Yes, but they are a completely different chemistry than the batteries that power laptops, cell phones, and Ipods. The chemistry is called Lithium Iron Phosphate (LFP).
2. How do I connect the battery?
Basically plug and play. TurnTech provides bolt/nuts so all that has to be done is connecting the positive battery terminal to the positive wire and like wise on the negative side. Just like a normal battery. HOWEVER, you will MAY need to find a way to keep it tight in the battery box as it is much smaller than the standard battery.
3. Will the battery charge?
They will charge just like a normal lead acid battery, you don't need to do anything special. However, if your system requires more power than the bike is producing it will eventually drain the battery. If you need more power from the system the battery will not increase the power the bike is putting out.
You can use a normal lead acid charger to charge the battery as long as the charger put out less amps than the capacity rating of the battery.
4. Is there a warranty?
Yes, there is a six month limited warrantee on the battery.
5. How much do they weigh?
Battery Weight
2.5Ah .8 lbs
5.0Ah 1.6 lbs
6. How big are they?
Battery Length Width Height
2.5Ah 4.625" 2.0" 3.5"
5.0Ah 4.625" 2.75" 3.5"
7. How long will the battery last?
The length of time depends on how you use it. The graph below shows the number of 18 second starting pulse the battery can do (this data is for the 5Ah battery). The yellow line is the actual capacity used during the starting pulse, notice that the X axis is in THOUSANDS.
8. How long can they be stored?
The graph below shows the voltage drop over time as the battery is stored at different temperatures. The batteries were kept at temperature 24/7 for the duration of the testing
9. How do they behave if I leave them on a trickle charger?
The graph below shows the capacity of the battery, tested once a month.
10. How is the low/high temperature performance?
The batteries don’t provide as much power initially as a lead acid battery at low temperatures. HOWEVER, the battery will self heat during the pulse, as the battery warms it provides more amps. The battery will get stronger rather than weaker as more starting attempts are made.
At high temperatures as seen above the life of the battery is reduced. At approximately 170°C (338°F) the battery will shut down and not provide any power.
11. How do I decide which battery?
I have recommendations for the type of bike with each battery. However each bike and situation is different. Below are some questions to answer if you are on the fence between two batteries.
Does the bike have a kick starter?
Do I have a normal clutch?
Is weight important?
Am I OK with the occasional kick start?
Is your bike an easy to start?
If the answers are mostly yes then the smaller will be ok. If mostly no then the larger will be a better choice.
THE SMALLEST battery the 250 and 300cc two strokes can use is the 5Ah.
12. Is there liquid electrolyte that can leak?
There is a small amount of liquid electrolyte in each of the cells that make up the battery. The battery is completely enclosed only leaks in extreme circumstances. Even if the cells are punctured most of the electrolyte is adsorbed by the films inside the battery and won’t leak out. The electrolyte is an organic solvent not much different than acetone (finger nail polish).
13. What is the voltage of a fully charged battery?
The battery should read under 15V and above 13.5V when fully charged (in most cased it will read 13.6-14.4V). The range is due to how it was charged and how long it has been since it was off the charger. The maximum voltage the battery should be exposed to is 16.5V.
14. Can you make a special battery different at a different voltage or amperage?
Yes. Contact Joe with your needs, 7.5Ah and 10Ah batteries take 2 weeks, custom batteries can take up to 1 month to complete.
