ControllerKelly KHB12401
Controller #3: July 2015 Kelly KHB12401,24-
120V,400A,Opto BLDC Controller/With Regen.
Set at 150A maximum (16kW to protect against
my EGO). Installed at 12,900 miles on

Controller #2: After 9,000 miles Kelly
KBL09401B burned out in July 2015 after
applied too much voltage from new Chevy Volt
Battieres. Specs were: Waterproof, 400A, 24-
96V - Set at 120 amp max. to protect batteries

Controller #1: Kelly KBL12271, 24-120V, 270A,
Burned out by riding it over two "5 mile
hills" in a row after 3,900 miles in the bike.
Was programmed at 120A Max.
Batteries28 Chevy Volt, 4.05 Volt, Lithium-Ion

Chevy Volt Batteries custom reconfigured to
have 28 Cells (100V-112V operating range).

Carry 1 or 2 45AH packs of 106V Nominal.

Original Batteries were Enginer Real-Force:
a7.6 kw-hr. 80 amp hour @ 96 volt

Recommended 1C discharge max. But, I
programmed controller to take 1.5C (12kW) max
and batteries have been taking it OK.

I recharge normally at .2C, but sometimes at

In practice, I've never taken more than 5.2
kw-hour out of it during ride. That is to
say, that is all this pack has ever been
capable of giving in this application.
System Voltage112 Volts
Charger Enginer
(4) Four, 15 Amp, 55 Volt Chargers

Recharge rate is 38 miles per hour (when
ridden at commuter speeds).

Recharge time is typically 1:15. Can recharge
at J1772, any four 120VAC outlets, RV30 and
RV50 outlets.

2 of my chargers are 110/220 so I can charge
at chargepoints with those.

2 of my chargers are 110 only, so I have to
find chargepoints that have level 1 and Level
2 to take advantage of faster charging.

Sometimes will charge using two Chargepoint
stations. I'll plug into the J1772 with two
of my chargers at Level 2. Then plug into
Level 1 outlet on one Chargepoint, and a Level
1 outlet on the second Chargepoint station.

For 110V charging I either plug into a
different circuit outlet for each charger
(each charger draws 10A at 110V).

At home, I've rigged an RV50 Plug that has a
pigtail with 4 110V outlets coming out of it
so it's easy to run all four chargers at once.

I have each charger on a timer so that I can
drop out 2 of the chargers early and not come
in hard and fast to top off the batteries.

Note: Fast charging does seem to put the
batteries out of balance much more quickly
than slow charging. Normally, I only have to
balance my batteries once per 3,000 miles.
HeaterOnly ride when above 32 degrees F (to avoid
ice), so with warm clothing it is fine.
Bodywork keeps you out of the wind.
