Battery Sizes and Capacities


Battery Pack Prices and Sizes

Revised 2/7/2017

Revision includes lower prices and updated dimensions.

Make the battery accessible.  Then you can use a smaller battery and replace a depleted battery with a full one

Some dimensions are rounded up to make sure the battery will fit.

Charger for the 14.8V 6800 Lithium Ion pack is $26.00. This charger will NOT charge the other packs listed.

All cells have a PCM which limits low voltage, over charge, and has short cirucit protection.

Battery packs come with a Polarized Connector. Mating Connectors are available.

All packs come with super flexible high temperature silicone wire.

Let me know if there are special requests such as wire length

Extra Polarized Connectors are available for $1.25

A charge cable with a Polarized Connector on one end and Banana Plugs on the other is available. Wire length 5″: $8.00

Pricing is not based on capacity. Cell cost and assembly costs are the main factors.

Charging

I recommend charging at 1/2C, but no more than 1C. C is the capacity. C in a 400ma pack is 400ma. 1/2C is 200ma.
250ma packs should be charged at 100ma. 450ma and 500ma packs should be charged at 200ma.

850ma packs should be charged at 400ma.

I only use commercial cells. These are the same cells that are used cell phones, instrumentation, and medical equipment.

The packs are not the same cells as Hi Rate RC Packs.
