GSL272 Posted August 6, 2021 Share Posted August 6, 2021 Hi, Can anyone inform me of the type of batteries required to power a Maxson 45 quad? Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted August 23, 2021 Share Posted August 23, 2021 I'm using 2x 6v 130ah lead acid batteries in series as per the original spec. I haven't got it fully operational yet, but have tested and does begin to show signs of loosing power. So in hindsight I would go for the largest ah 12v/6v combination that fits on the tray. I did enquire with Lincoln Batteries and they suggested a deep cycle battery would be suitable. Just means you can run the quad longer. Hope that helps.

GSL272 Posted August 24, 2021 Author Share Posted August 24, 2021 Hi, thanks for that info it does help. I was looking to put two 6v ones in but after your experience I might try the bigger 165AH batteries which should just fit the tray. I suppose a large 12v is a possibility also? cheers Alistair Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted August 24, 2021 Share Posted August 24, 2021 I would definitely go with the largest that will fit, no harm in it really. 12v would work as well, you could even put them in parallel I imagine and have even more capacity. Just not manual spec. When I enquired about a 12v deepcycle battery I think I was looking at around 200+ah that fitted in the tray. Is yours running yet?

GSL272 Posted August 24, 2021 Author Share Posted August 24, 2021 Yes I’ve ran it of a 12v battery, need to finish restoring the Tiny Tim genny to get everything working 😅 Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted August 24, 2021 Share Posted August 24, 2021 Nice, did you notice any high current draw or overheating on the motor? For the past 5months the motors been in and out trying to work out why it's pulling 150amps. Currently being rewound which hopefully will get to the bottom of it.

GSL272 Posted August 24, 2021 Author Share Posted August 24, 2021 No nothing untoward, I guess I was lucky with this one 😬 good luck with yours 👍 Quote Link to comment Share on other sites More sharing options...
GSL272 Posted August 31, 2021 Author Share Posted August 31, 2021 What generator have you on your Maxson, mine is a Tiny Tim L123 12v output one which I am not sure is correct? Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted August 31, 2021 Share Posted August 31, 2021 I'm hoping to use a WW2 PE-77 (Briggs and Stratton)which is 115v. I'm currently trying to convert it down to 12v with a buck converter and a few other bits. I got some spare parts from Antique Briggs in the USA. I believe the correct genny is Power Charger 7386579 (briggs and stratton)which is 12.5v 15-20amps according to the manual. Quite hard to find I think. Haven't heard of the Tiny Tim, does look different to the ones I've seen on a Quad. If it fits and runs a solid 12v might be worth trying.

Chris Hall Posted September 24, 2021 Share Posted September 24, 2021 I’m told by some guys in the US that the Quad will only run for about 10 mins on fully charged batteries before the voltage begins to drop and current draw goes up causing over heat. this is the power set I have to use.

Chris Hall Posted September 24, 2021 Share Posted September 24, 2021 There’s an early war version and a postwar Korea version. The post war version is much bigger, I have photos somewhere. Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted September 25, 2021 Share Posted September 25, 2021 That looks great, definitely the correct generator for a quad. Have you got it working yet? I'd be interested to know the operational current output. I have just lifted the quad onto the trailer and now its mounted correctly the current draw has shot up from around 130amp during testing to 150-200amp which is not sustainable to run on really.

Hi, just checked my motor and it’s pulling 154 amps. What should it be? did you get your issue sorted? Quote Link to comment Share on other sites More sharing options...
GSL272 Posted November 22, 2021 Author Share Posted November 22, 2021 Ben, do you have a Code for the correct belts? I’m wondering if mine are too long, the differential bolts are at there max no I still have too much play on the belts? Alistair Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted November 22, 2021 Share Posted November 22, 2021 Hi Alistair, I'm not 100% sure these are the correct belts, but they were the closest match to the manual spec I could find. I did speak to Gavin at Jeeparts and he had a guy come over to match up the belts. Might be worth a phone call. Link: https://simplybearings.co.uk/shop/p516003/A18-Major-Brand-A-Section-V-Belt/product_info.html Have you found any good parts supplies for the Quad? I'm looking for a few bits and pieces to finish it off. Thanks, Ben Quote Link to comment Share on other sites More sharing options...

GreenEagleKing Posted November 22, 2021 Share Posted November 22, 2021 Is it this one? WW2 Quadmount / Maxson m45 m55 Parts Trader And Discussion Group I've just been sent for approval. Didn't realise there was one! Thanks Quote Link to comment Share on other sites More sharing options...
Chris Hall Posted November 22, 2021 Share Posted November 22, 2021 That’s it, not many members as yet but it’s building up. I picked up some Quad rings recently for the Halftrack and got a power set cover and new seat coming. I think I’ve identified the connectors for the firing solenoids but need to check the spec against what are on mine. I also picked up a battery hold down frame and step from the states.

GSL272 Posted November 29, 2021 Author Share Posted November 29, 2021 Ben, I bought some of those belts, a lot better fit than the ones I had, thanks for that. elevation still incredibly poor, traverse is spot on! Thinking I might have to unbolt from the trailer and hoist it off to take a better look, do you know the measurements for the 3 legs? I’ll have to rig a stand up to set it on. 👍 Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted November 30, 2021 Share Posted November 30, 2021 That's good to hear the belts are better. I'd definitely recommend dropping the mount out of the trailer, it will make it easier to adjust everything underthere. Im not at the garage until the weekend. I can send the measurements then if you'd like? Quote Link to comment Share on other sites More sharing options...
GSL272 Posted November 30, 2021 Author Share Posted November 30, 2021 Cheers Ben that would be good 👍 Quote Link to comment Share on other sites More sharing options...
GreenEagleKing Posted December 13, 2021 Share Posted December 13, 2021 Sorry totally forgot to take the measurement. If it's not too late the legs measure 29cm from where it mounts onto the base to the feet. Let me know if you need anything else. Quote Link to comment Share on other sites More sharing options...
