How do you charge the EV warrior? - UPG 12V 18AH Electric Bicycle Co EV Warrior Bike Battery - 2 Pack - UB12180MP21162

Yes, But. 2 pack so 6volt each, I will assume standard lead acid batteries as the is common, and that is what the pic shows. depends on what you call standard charger, I would not do it with my 40 year old standard charger, although at a push, it will still charge them, but need to keep a check on them, later chargers, monitor the battery voltage, and adjust output to suit. All chargers work the same way, so basically yes, but keep a check on them, not running to hot etc. check voltage if you can. But they all work the same way, just later cells are used to the controlled cct of later chargers. especially with them being so called sealed, they still let gas escape, via a pin hole, If they get hot, to much gas, going out, reduces the effiency of the electrolyte, so will reduce the life, BUT as long as you keep checking them and stop if they get hot no problem, they will get warm anyway.

A unit of energy used for convenience in atomic systems. Specifically, it is the change in energy of an electron, or of any particle having a charge numerically equal to that of an electron, when it is moved through a difference of potential of 1 mks volt. Its value (in mks units) is obtained from the equation W = qV, where W is energy in joules, q the charge in coulombs, and V the potential difference in volts. For a potential difference of 1 volt and the electronic charge of 1.602 × 10?19 coulomb, the electronvolt is 1.602 × 10?19 joule. See also Electron; Ionization potential.

Conversion factors:

• 1 eV = 1.602176487(40)×10?19 J (the conversion factor is numerically equal to the elementary charge expressed in coulombs).

The kinetic energy gained by an electron by falling through a potential difference of 1 volt. 1 eV is equivalent to 1.6 × 10-12 ergs. 1,000 eV is referred to as 1 kilo electron volt, or keV, and 1,000,000 eV are referred to as 1 mega electron volt, or MeV.

From this equation W = qV = (5 x 1.6 × 10?19 Coulomb) x 8900 v = 44.500 x 1.6 × 10?19 Joule
= 44.500 eV (because 1 eV = 1.602176487(40)×10?19 J)
= 44.500 x 10?6 MeV ( because 1 MeV = 1.000.000 eV)
K.E. = 0.0445 MeV

Well, I hope this right, I'm not so sure my self :P.
Hope this help and be kind to rate please, thanks.

try to search for it on the web i'm sure it will be of some help 2 u please vote 4 me

I have a PDF of the schematic i drew for my bike. it is posted on the Yahoo power-assist group. look in the files section.

http://tech.groups.yahoo.com/group/power-assist/files/EV-Warrior/

there is also a text file there that lists all of the wiring connectors and where each of the wires goes. as well as connection diagrams for the Curtis 1505 speed controller.

the charger circuit is very simple. the black and red wires from the charger port go straight to the batteries +24V and 0V terminals. the third white wire connects through a bullet connector to pin#7 (EPO wire) of the Curtis speed controller. this acts to turn off the motors while the batteries are being charged.

inside the charger male connector the pin for that 3rd white wire is shorted to ground. so when you plug the charger in the white wire is grounded thru the charger plug.

have fun. i really enjoyed my EV-Warriors while i could still ride them.

Hi,
your NG3 should have been preprogrammed for the type of batteries you are charging. The NG3 has the 3 wires from the power cord. Here is what I have done:
Brown from charger goes to black wire
Blue goes to white wire
yellow green goes to green ground.

hi, since u say the wires were hot , that means -ev and +ev got shorted, that might have damaged the power supoply, or the polarity is reversed,if u can manage to open the adapter, then try replacing the fuse if present , and the filter capacitor. let me know
