TheBeastie Posted April 15, 2010 Share Posted April 15, 2010 I have two "normal" batteries squeezed into my standard battery box on The Beastie, linked by an X-Charge system. The main battery is to start the engine etc, and the second is to run my radios and an inverter. I suspect that the second battery would be better as a deep cycle battery due to the pattern of usage (usually with engine off and running radio with up to 100W output on Tx). I noticed last night that as I was transmitting my internal LED lighting (off same battery) was showing severe dropping of voltage and flickering a lot. What, I wonder, might be the optimal "mix" of batteries for such a setup given I want to keep it all in the battery box? I have seen pictures of two red top Optima batteries but not sure if this gives best mix since the usage requirements for starting the engine and running radios seem quite different. Any suggestions most appreciated. Quote Link to comment Share on other sites More sharing options...
western Posted April 15, 2010 Share Posted April 15, 2010 a PC1200 Odyssesy would do well, here these are quite happy with deep cycling but expensive, but then so is radio kit. I have 2 of the PC1700 one for the vehicle & radio's, 2nd just for the winch. Quote Link to comment Share on other sites More sharing options...
TheBeastie Posted April 16, 2010 Author Share Posted April 16, 2010 Thanks Western. I knew they were more expensive but had no idea they were that expensive! Am just about to upgrade from roof bars to hopefully a Brownchurch roof rack so I may have to live with the battery for a bit longer but at least now I know what I need to sort it.
