Q1: Where do I get repairs and updates to Tekin Products?

A1: Check out the Service Request page. You can find information there on how to get your products fixed and upgraded.

Q2: Where can I get Tekin decals?

A2: To get some decals send a self addressed stamped envelope to:

Tekin
PO Box 2189
McCall, ID 83638

Q3: Where can I find the specifications on Tekin Products?

A3: Product specifications can be found on each product page.

Q4: Is it beneficial to send in a B112C with the H28 software to upgrade to the newest level? At what cost?

A4: The H31 software includes a better way of detecting the peak charge of NiMH batteries to prevent overcharging and damage to the cells. It also makes some changes to the display. The cost to update the software on the BC112 is $50.00 excluding shipping and handling. The turn around time is quick.

Q5: What is the nominal DC output and amperage for the BC112 C?

A5: Nominal DC output = 30 Volts. The combined draw of the BC112C power supply can not exceed
10 amps. If a BC112A is connected to the power out of the BC112C then the total of the
cannot exceed 10 amps.

Ex. Charger1 + Charger2 <= 10 Amps.

Q6: Is it possible for me to buy the upgrade chip for the BC112c and install it myself?

A6: Sorry, but we don't recommend installing the upgrade chip by yourself. Check out the service request page for more information.

Q7: Do Tekin chargers working with the 3300 batteries?

A7: Tekin BC112 C/A chargers have no problems charging 3300 batteries. The unit can basically run continuously at reasonable charge rates. This should have no effect on the peak detection methods.

Q8: Is the Tekin BC112 C charger a Pulse or Linear charger? Does it matter what type of batteries it charges?

A8: The BC112 C is a linear charger. However there is Powerflex mode which pulses the cells. This was designed for NiCd's but may provide some benefits when charging NiMH cells as well.

Q9: Does the BC112 have or use negative delta V peak charge rate?

A9: The BC112 has negative dV/dt peak detection and zero dV/dt peak detection (P0 mode). The negative dV/dt peak detection is used more for NiCd batteries, because NiCd batteries peak at a voltage and then start to decrease in voltage. The zero dV/dt peak detection is used for NiMH batteries. This is because when NiMH batteries charge they reach a peak voltage and then hold that value for a period of time. The zero dV/dt peak detection picks up this plateau and stops the charge. The H31 software is the latest software and it supports negative dV/dt and zero dV/dt peak detection.

Q10: Are the BC112C's AC and DC capable?

A10: The BC112C will accept standard 120V AC and 10-24volt DC.
The BC112A is DC only.

Q11: Is the Tekin BC112C available for 240V?

A11: The transformer for the BC112C chargers will not accept 240V. A different transformer is required. The transformer specifications are custom for this product. You will not find an off the shelf replacement that will work correctly. We have BC112C chargers in stock that will work with the 240V systems.

Q12: Why is there an infrared data port on the BC112C/A charger?

A12: The intention was to be able to download the battery data to a PC. The chargers can only display the data for the last charge or discharge. With a separate software program you could track performance over its life span or during cycling. Will we continue this project? How about a solid maybe.

Q13: Can you charge NiMH on the newer BC110 charger?

A13: No, the only chargers that will correctly shut off without damage to NiMH batteries are the BC112A & C with H31 software.

Q14: Is the older model BC 870 charger compatible to charge the new NiMH 3000 MAH battery packs? If so, should I change the charge rate for charging them or do anything to the charger to be able to use it?

A14: We don't recommend using any chargers but the BC112A or C when charging NiMH batteries. The problem with the older chargers is that their peak detection circuit is not sensitive enough to automatically detect the peak of NiMH batteries. As a result the charger will not turn off and you batteries will be damaged.

Q15: Is Tekin repairing the BC67?

A15: We do service the BC67. Follow the request for service on our website.

Q16: Will replacement parts be available? Ex: replacement FET's for the chargers: instead of having to send the unit in for repair.

A16: Many of the user serviceable parts are available in the online shop.

Q17: Does the G10 Series need capacitors or a motor diode?

A17: There are no external caps. or motor diode needed for the G-10 Series. These units have Tekin's patented circuitry that eliminates the need for a battery cap and motor diode. Another great thing about Tekin speed controls.

Q18: How many discrete throttle steps does the G-10 Pro have?

A18: 384 effective throttle steps.
