Trickle Chargers / Battery Maintainers
Ever used a trickle charger to try to maintain a battery over a
storage period of a few months, only to find it has reduced
capacity when you go to use it again? So did we. Now we use a
charger with smarts, instead of one that just cooks the battery
slowly. For typical 12-volt batteries (boat, motorcycle, ATV, lawn
or garden tractor, generator, automotive, RV, etc), we recommend
the Soneil
1206SX. At
our price, it probably costs less than the
battery you're trying to save, or one of those old-style battery
slow-cookers.
Trolling Motor Batteries
There are two significant aspects to keeping batteries for
trolling motors charged: a fast charge when the battery is in
regular service; and, a maintenance charge when it is not. Now,
you can have one smart charger that will do both, automatically.
For normal situations (overnight charging acceptable, one 12-volt
lead-acid battery weighing less than 20 kg or 44 pounds), we
recommend the Soneil
1205SRJ. (This charger not suitable for use in series
or parallel charger arrangements. Batteries can be combined in
series or parallel.) If you need faster recharges, we recommend
the Soneil 1220SR.

ordering page. If you have questions, say about connectors,

Modular EV Chargers
Many EV users want to charge each battery in their pack
separately, so that batteries are maintained individually, not
undercharged or overcharged because of the overall pack condition.
The compact, lightweight and intelligent Soneil chargers are ideal
for this application. Which specific charger you select will
depend on the nominal voltage of your battery modules (e.g., 6 or
12 volts), and the rate at which you want to charge them, and
possibly the capacity of your mains charging circuit. Contact us
with your specifics, and we will figure out which Soneil charger
is most appropriate for your vehicle. (We use the
Soneil
1212SR in our latest on-road EV project, one on each
of our twelve Orbital XCD34 batteries. They all run off a single
15-amp, 120-volt circuit.)

Electric-Assist Bikes
We love electric bikes; in fact we successfully campaigned to
get them legalized in Ontario. (A 3-year pilot project was
announced on October 4th, 2006, which covers most electric assist
bikes, provided you are 16 years of age or older, and wear a
bicycle helmet.) On most electric bikes, the objective is to have
a small, light battery pack to drive the electric motors, but not
exhaust the rider. So why use a bulky, heavy charger? The Soneil
chargers are small enough and light enough to bring along on the
commute, so you can recharge the pack at work as well as at home,
and smart enough not to overcharge the batteries with the
additional charging opportunities. Of course, you might find them
so affordable, you'll have two. With one at work and one at home,
no need to carry the charger with you. Which charger will be most
appropriate will depend on your pack voltage (e.g., 12, 24, 36, 48
or 72 volts), desired recharge rate, and budget.
We have a Soneil
3602S for our home-built 36-volt electric bike.
Affordable, and it can recharge the 7 amp-hour pack in about 7
hours, ideal for charging at both ends of a commute.
Unfortunately, with many electric bikes, the charger that is
supplied with them is the cheapest thing that will push electrons.
If you want to protect your battery investment, or if your OEM
charger fails, consider getting a Soneil charger as a replacement.
If you have a Schwinn electric bike that's a couple of years old,
and this spring it doesn't have the get-up-and-go you remember, it
might not be the battery pack - or at least not completely. We are
seeing a number of charger failures on these machines, especially the
24-volt models (such as were sold by Canadian Tire). If you are having
this problem, we recommend either the Soneil 2409SR (for bikes getting
a lot of use or needing relatively fast charging) or the 2404SX (for
less demanding charging requirements). (Please keep the battery
connector from your existing charger for re-use as we have not yet
found a source for the odd plugs used by Schwinn on those machines.)
Of course, we also have 36-volt models (like the 3605S and 3602S)
for bikes using that voltage, be it lead-acid, nickel-metal-hydride,
or even some LiFePO4 packs (depends on recommended maximum cell voltage
from the manufacturer - always use a BMS on lithium batteries).

ordering page. If you have questions, say about connectors,
e-mail us.
High Current / Fast Charging Applications
We are pleased to announce the recent addition of high current
chargers to the Soneil product line for 12-volt (up to 50 amps
constant current), 24-volt, 36-volt (up to 30 amps constant
current) and 48-volt (up to 20 amps constant current) lead-acid
battery systems. If your application demands high current, fast
charging, these units deliver it, with an intelligent charging
algorithm, in a small, lightweight package. (The constant current
ratings apply to the initial bulk charge phase. Current during the
charge maintenance phases is lower as appropriate to the stage.)

We don't usually stock the high current chargers due to limited demand.
Soneil continues to add chargers to the mid-range and high-current ranges.
However, we would be happy to answer your questions, or get them for you.
Just ask.
Special Requests, Handling, Shipping
We provide most connectors as requested by our customers for a small fee
(e.g., ring terminals, quick disconnects –
male or female) for their convenience. Unusual connectors, Gerbing connectors and
Anderson connectors incur an extra charge. For XLR connectors
(male on the charger), please specify your pin-out connection
requirements. We normally ship expedited postal delivery (three or four business days delivery),
but will ship whatever way you want. We will try to accommodate
any special shipping or handling requests. All shipping charges
are extra. All applicable taxes are extra. Canadian residents pay
GST or HST as appropriate.
For your convenience and confidence, we accept payment via
Interac E-mail Money Transfer and PayPal.
(We still want to talk to you about your application first, so feel free to e-mail
before ordering.)
