My On Board charger get's so hot I can't keep my hand on it, is this normal?
Yes, the On Boards are not ventilated so all the heat generated is dissipated through out the aluminum housings that are a heatsink. A temperature of 160-180F is not uncommon.
I put a volt meter across the charger output leads and nothing comes out, Is something wrong?

Firm statements we feel comfortable making are:
Always recharge if your batteries are discharged more than 20%. A volt meter, or fuel gauge will be needed to measure this.
Do not leave your batteries in a deep discharged state. This is probably the number one cause of premature battery failure. We provide a battery
Recharge as soon as you can, but not if the batteries are warm, allow a cool down time.
If you're not going to use your batteries for extended periods, leave the charger plugged in and let it float/maintain. Lead acids self discharge, and in some cases you can return to find your equipment disabled, and your batteries ruined if the charger is not left on.

They include:
Not lengthening the cycle for these batteries will result in undercharging, and underachieving maximum battery life. See your manual for how to lengthen the cycle.
Small chargers on big batteries can also benefit from a longer cycle.

Large chargers on small batteries may also need a shorter cycle.
In addition to the three stage profiles, we also provide a single stage constant voltage profile for gel batteries having critical voltage limits, or starting batteries that can charged with a constant voltage.
Will using the wrong profile setting harm my batteries?
ALWAYS CHECK THE CHARGER PROFILE SETTING BEFORE USING.
I'm switching to a lithium ion pack. Will my charger work?
For Lithium Iron Phosphate 3.2 volt LiFePO4 cells, we need to establish how many cells you need to match the charger.
IF 12 volt charger, use 4 lithium cells
24 volt = 8 cells
32 volt = 11 cells
36 volt = 12 cells
48 volt = 16 cells
64 volt = 22 cells
72 volt = 24 cells
96 volt = 33 cells
120 volt = 40 cells
144 volt = 49 cells
Using fewer cells will make the charger run hotter, and shorten it's life. Using more cells will cause weak output and extend the charge cycle or the charger will fail to fully charge the cells.
These cells, and most commercially assembled packs are charged to 3.65 volts. In this case the voltages are about the same as charging an AGM lead acid battery, so using that profile, you will be able to charge your lithium pack.
If you require a charger to operate from a different number of cells, or with a different nominal voltage a different charger may be needed. Please contact us with your specific need.
Do I need a BMS (battery management system) for my pack?
Yes, most pre assembled packs come with the BMS installed.
High frequency switch mode power supply chargers. What's the difference with traditional transformer based chargers?

GLOSSARY OF TERMS THAT WE USE.
Charge Profile: A setting the determines how the charger charges the batteries. This term is only relevant to the last 20% of the cycle.
Bulk Cycle: Up to 80% of the cycle where max power is put into the battery. Program settings have no affect on this cycle. It is controlled by the internal resistance of the battery. As the voltage builds the amperage will naturally taper.
Gassing cycle:The last 20% of the charge cycle where a wet cell battery bubbles vigorously to stir the electrolyte, preset max voltage is met, and amperage is allowed to fall to the lowest point possible.
Absorption Cycle: The last 20% of the charge cycle on an AGM battery where preset max voltage is met, and amperage is allowed to fall to the lowest point possible.
Float Mode: When the last 20% of the charge cycle is complete, the charger drops into this mode to hold the batteries in a full charge condition. The voltage is held between 2.22 to 2.27 volts per cell. Amperage to maintain this voltage can be between 10 or 20 milliamps all the way up to 1 amp or more depending on battery size and age.
Maintenance Mode:If the charger is set to shut off completely, the battery will continue to be monitored, and the charger will turn itself back on based on time, or a minimum voltage so the batteries will not self discharge to a dangerous level.
Safe Mode: When a charger is connected to a severely discharged battery, output amperage is limited to about 10% of the charger output rating to prevent excessive current flow. Once a safe voltage level is met the charger will automatically enter the normal bulk mode and continue charging.
Constant voltage: A single stage setting where a preset voltage is met and held indefinitely.
Current Limit:A setting that does not allow amperage output to exceed the rating of the charger.
Lead Acid Battery: All batteries that require water, starting batteries, deep cycle batteries, AGM batteries, and GEL batteries. They are all lead acid batteries.
