Hi cruisinon2 I appreciate your input. I'm thinking after following this situation for some time, to use an 8000 mAh 16340 3.7v battery in place of the ICB17280 600 mah 3.7v battery. I know it won't fit into the structure however will retro fit it and to tidy it up use some shrink wrap. I think when fully charged and used in my particular circumstance it will allow the G10 relay to last a VERY long time and will need very little recharge cycles. Given the 8000mah battery can receive 500-1000 cycle recharges; I'm hopeful this will last me forever so to speak. I've bought a pack of 4 batteries to quick fix the next time.
