I have several HD servos to operate so I need external power supply. As I am inpatient to wait for ez bits, how do I go about supplying external power for these servos? I am okay with modifying the EZ-B v.3, I just don't know what I need to do. Help, anyone?
I have them attached in the smaller block of DIOs and was wondering if it was possible to only alter these, or if the alteration affected all DIOs?
THESE ARE HIGH EFFIENCY AND WOULD BE.IDEA http://www.ebay.com/itm/Grade-125x125-Monocrystalline-Solar-Cells-2-8-Watt-Mono-5x5-Photovoltaic-Lot-/120775475856?pt=LH_DefaultDomain_0&var=&hash=item61cc995fe0

These will accept a low ampere charge well , sealed , gel/glass filled
Thats the thing about those is easier charging .
That's what I'm using on Omnibot, BOB. I have one in him and it works fantastic! I power the board, and also my motors and HD servos off this one battery. That way everything shares a common ground. Speaking of charging, what would I need to charge one of these batteries (haven't needed it yet)?

Charger 6v , 1 am hr , charges up in about 4 hrs
7 bucks shipped , buy two and charge extra battery.
AGM and gels last a lot longer if you slow charge them. Keeps from drying them out. I'm not sure about the voltage on a 6 v but 12v ones are 14.1. I would guess half at 7 volts and 6.2 to maintain J.W.
@jstarne1 Thanks!
A slow charge is 1.7 -2 volts over the battery rating at a rate between .7 and 1.5 ah . I bought a motorcycle computerized battery charger /maintainer that charges 1.5 amp from walmart. But I have 2 batteries so that's .75 ah per battery which is optimal slow charge. I leave them overnight. The charger I bought from walmart for 6 or 12v batteries was 20 bucks.
