YANDINA C100 Lithium Combiner 100
SUMMARY
The Combiner 100 is a precision voltage-sen sing relay (13.0-volts) that connects two batteries together when either is receiving a charge. When the charging ceases, it disconnects so that each battery operates independently and prevents accidental discharge of the starting battery. Supplemental battery banks can be added by using an additional combiner for each bank. It eliminates manual switching every time you start the engine to parallel batteries for charging. Never again forget to switch it back. No diodes so no voltage drop, and the batteries get a full charge.

J Withstands ambient temperature to over 175 F (80 C) for exposed or engine compartment mounting.
SAFETY CONSIDERATIONS
DANGER: On all alternator/regulator circuits with an external sense wire
it is critical that the sense wire can never be disconnected from the
alternator output Damaging, self-destruct voltages may be produced.
Installation of a Zap-Stop will not protect against damage if this happens.
WARNING: If there are switches which can disconnect the alternator output
from the battery a Zapor similar protection diode can reduce the chance of
Stop alternator damage and it is recommended for all installations. Switching
off the output from the alternator should be avoided when the engine is
running. Since the connections made in the battery circuits can carry hundreds
of amps, it is imperative that you have low-resistance connections. This means
having clean metal-to-metal contact, the right size ring terminals, properly
crimped terminals (preferably soldered also), and secure mechanical
fastenings.
BASIC INSTALLATION
- Connect the BLACK ground wire to the common negative of your battery banks. Shorten if necessary
- The RED cables connect to the positive terminals of the batteries. SHORTENING THESE POWER CABLES WILL VOID THE WARRANTY. Extending is OK. The connection does not have to be made right on the battery terminals but any wire or cables between the battery and the combiner must be heavy enough to carry the combiner current in addition to any existing loads. Make sure the second red lead is not touching ground when you connect the first since the combiner sometimes closes momentarily when initially connected.
- Any other wires are not normally used and should be secured and the ends insulated. See Appendix.
With Single the engine Combiner 100 powerboats: you can use an (optional) OFF-1-switch to select the engine power source and leave BOTH-2 the DC loads permanently on battery 2. Starting power is normally supplied from the starting battery in position 1, but battery 2, or both can be selected in an emergency. In all cases, both batteries are being charged when the engine is running.
WARNING: If you use this circuit, turning the switch to “OFF” while the engine is running may damage your alternator. If not using a switch, the motor connects directly to the starting battery.
Auxiliary battery for commercial vehicles or mobile
sound systems. Make sure the alternator is rated for 100 amps or less. If it
is greater than 100 Amps, you need to upgrade to the Combiner 200 or the
Combiner 600. The auxiliary battery must be securely mounted in a convenient
location. If mounted in the passenger compartment, it should be separately
enclosed and vented outside the compartment, or you can purchase batteries
with built-in vents to which tubing can be attached. Both batteries must have
their negative terminals connected together, either by a heavy cable or
through the vehicle chassis. If the batteries are close to each other, just
connect one red wire to each positive terminal and the black wire to ground.
If the batteries are separated by more than a few feet, the combiner can mount
at either end and you need to consider some protection for the positive cable
between the batteries. See the section on FUSES & CIRCUIT BREAKERS. 10- gauge
wire is adequate but if you are concerned about voltage drop, upgrade to
8-gauge. Do not shorten the existing red wires on the Combiner.
Travel trailers and motor homes.
These vehicles typically have a “house” battery already installed. Make sure
the alternator is rated for 100 amps or less. By connecting the Combiner 100
between the starting battery and the house battery, the unused capacity of the
alternator will be automatically directed to the house battery while underway.
Since the Combiner 100 is bi-directional, a shore power charger on the house
battery will also make sure the starting battery is at full charge. Neither
system will draw power from the other battery through the combiner, so there
is no risk of discharging the starting battery.
BATTERY CHARGERS
A single output shore power charger can be directly connected to the house
battery. Multi-bank chargers are no longer required, but can be connected to
each of the battery banks.
OPERATION
The green “Combined” light will come on some time after charging has commenced. The time delay depends on how much current is being delivered to the bank being charged, and its initial state of charge. When the initial bank reaches 13.3-volts (±1%) the other bank(s) will be placed in parallel by the Combiner 100. If one bank is very low, the Combiner 100 may turn off and on a number of times as it brings it up to voltage. After charging has ceased, the green light may remain on for quite some additional time if there is no load on the batteries, due to the “float” voltage above 13.3-volts left over from the charging. If the internal temperature of the Combiner 100 rises too high, the red “Overload” light will come on and the Combiner will turn off to protect itself. After it cools by about 10 F (6 C), it will turn back on automatically. The overload condition should not be permitted as a regular occurrence, as charging capacity is being lost.
FUSES & CIRCUIT BREAKERS
Accepted wiring practice guidelines dictate that all 12- volt circuits, except
starter motor leads, should be fused. However, there is no path to ground
inside a battery combiner that can carry any significant current, should it
suffer an internal failure. Fuses in the battery lead to the combiner only
providing protection from a short to ground on the battery cables themselves,
which must pierce the insulation. Conduit covering can reduce this risk. If
it is a metal vehicle and the unprotected cables are close to a grounded
metal, the risk of a short is much higher and fuses may be a good protection.
The size of the fuses has to be much higher than the charging current
available because when the combiner first closes, quite large currents can
flow from one battery to another. These battery-to-battery currents are
limited by the wire gauge and length of the red wires which must not be
shortened. A slow-blow fuse of approximately 30% to 50% of the total Cold
Cranking Amp capacity of the batteries in the smaller bank is a guide to
value. Although the risks are minimal without a fuse, the results of an
accident can be catastrophic and even life-threatening. A disconnect switch
located close to the positive battery terminal to allow isolation for
emergencies and regular maintenance is a good design.
APPENDIX
REMOTE CONTROL
This feature is very rarely needed. We suggest you run without it for a while
to see if there are any situations where you would use it. The GREEN REMOTE
wire is left unconnected for automatic operation. It may be cut short if
desired. It can be connected through a single pole, center off, and double
throw switch for remote control. Switching it to ground forces the Combiner
100 off, and switching it to +12 forces it on. The response of the Combiner
100 to remote operations is delayed by turn-on and turn-off timers. When
disconnected in the center position, you are in automatically. If you only
need one function, a simple on/ off switch will do. The remote control input
is purely voltage sensing, so a light gauge wire is sufficient. The BLUE WIRE
is rarely used. If connected to the battery to be charged it will limit that
battery to 14.2-volts maximum. The red OVERLOAD LED will flash when it is
regulating voltage. The red LED may flash and the combiner turns off during
engine starting if the battery voltage gets less than 10 volts.
