VENDOR QUESTIONS AND ANSWERS

Q- We are a battery pack manufacturer, and I know that we can build this pack. We have already determined the layout, but the specs given are incomplete:

A- Charging port requirements: Each of the four 12V 10Ah NiMH battery packs have their own charging ports, 18AWG wire with mini Tamiya connector male and connect with a 65 degree thermostat, are charged individually and are never connected in parallel for charging.

Q- Are the four 12V 10Ah NiMH battery packs parallel connected internally, or are they parallel connected by using the 4 Tamiya connectors?

A- Discharging port requirements: Each of the four 12V 10Ah NiMH battery packs must have their own 14 AWG wire standard Tamiya connector male, coming from each pack and must include one 4 to 1 Parallel Tamiya Connector to make parallel connection of four 10Ah 12V Modules, and form a 40Ah battery pack. Each of the four 12V 10Ah NiMH battery packs must be able to be charged in 7-9 hours at a rate of charging rate of 1.8A Max (1.75A standard). Charging must be accomplished using a Multi-Current Universal Smart Charger for 9.6V - 18V NiMH/Nicd Battery Packs or equivalent.

Q- Are the four 12V 10Ah NiMH battery packs shrink-wrapped together to form one bundle?

A- The four 12V 10Ah NiMH battery packs shrink-wrapped together with by heavy duty heat shrink tube to form one bundle in size of 13.25"L x 5.35"W x 2.35"H. Both the charging and discharging ports’ lead wires extend out from the shrink wrap to a length of about 6 inches to the mini Tamiya connector male (charging leads) and standard Tamiya connector male (discharging leads). The 4 to 1 Parallel Tamiya Connector to make parallel connection of the four 10Ah 12V Modules is about 12 inches in length.

Q- Are there any other insulation or shrink-wrap requirements?

A- No other known specifications for shrink wrap, standard insulation required for safety and specified to life of 500-1000 charge/discharge cycles.

Q- Does each Tamiya connector go to only 1 of the 12V 10Ah battery strings, or are all 4 of the 12V 10Ah assemblies paralleled in such a way that each of the Tamiya assemblies has electrical access to the full 40Ah pack?

(If this is the case, each Tamiya mini-connector would also be able to charge the battery pack by itself.)

A- Each Tamiya connector will go to only 1 of the 12V 10Ah battery packs, and connected in parallel on the discharge port with the 4 to 1 Parallel Tamiya Connector to make parallel connection of four 10Ah 12V Modules, and form a 40Ah battery pack. The charging leads and individual to each 12V 10Ah battery packs and never are connected together to prevent uneven charging.

Q- Do you have any pictures of the battery pack, particularly one that is cut open?

A- Photo is included as an attachment in beta.SAM. A photo of the cut open battery pack is not available.
