Caravan & Camper Battery Charging

Hi all, I'm having a few dramas with my 200Ah lithium B-TEC from Enerdrive. I have 2 different water pumps and they both seem to be causing the BMS to cutout when the pump is priming or switched on. The battery state of charge is 99% and the battery volts is at 13.4. The pumps only draw a max of 3.5 amps and they are not tripping a 5amp fuse. I have a whole lot of other accessories that do not cause this to happen including a fridge/freezer, uhf, a few lights, and even tested my air compressor which draws 40amps and it did not trip the BMS. Does anyone have any advice on how to stop the pumps from cutting out the BMS? Thanks - Pat

Hi all. Going outback soon. Have a near new 120 ah deep cycle battery which I intend to charge using panel and redarc srpo120 controller. My second battery (which came with camper) is a "100ah" wet cell . It'charges ok but I'm not happy with its performance on a discharge test using the Engel as a load. So I'm looking at getting another deep cycle agm to replace it. Can get a good deal on a 100ah agm of a different brand to my first battery . The battery guy says both batteries should be identical if I want to charge both from the redarc. The redarc manual says they just need to be the same type. I guess I could ask redarc but need an answer by tomorrow if possible as will be opportunity to pick up new battery on Saturday. What do you think? Anyone charging different brand/size batteries with the redarc.? Thanks doc

Hi all, Currently on a 9 week trip exploring WA, woke up this morning with a warm fridge. The fuse going into the Redarc bcdc had melted. Replaced it but the unit looks like it has failed, I think it's 3 months out of warranty. I bypassed it with a parallel wire directly to the 2nd battery and that appears to also not hold a charge (I'll take it for a big drive tomorrow to be sure). I should be in Broome on Tuesday to get the battery checked/replaced. The battery was checked in Darwin a few weeks ago and I was told it was ok. The temperature has been so hot I have noticed the fridge running longer than normal to keep up. It's a Century Marine Pro Battery (also just out of Warranty). My question is does it really make a huge difference to have a dcdc converter versus just a simple isolator? All I run is a small Engel fridge and 1 Led light. I'm loathed to purchase another Redarc considering it only lasted 26-27 months. In my old GU Patrol the Smart Isolator from ARB lasted for years. Thanks Phil P

HI , To all ,What are all the different types and brands of batt charger out there that are usefull to members eg to charge a single 120 amp AGM or a twin batt 120 setup.?? Is there any with adjustable amperage ?The preference is for a charger that will work with a 1kv gene . There are I think whats called power factor corrected types that use less power to run eg u can achieve a higher charge rate with these on a 1kv gene. Trying to charge around the 20-30% of a/hr capacity of agm or max 30 amp single and at least 20 amp each for double Xantrex true charge 20,40 and needs a remote for adjustability lots of dollar 700 plus The remote panel has too be purchased to adjust amperage % 100, 80 ,60,40,20, votage profile is your typical agm flooded gel etc manual dip switch Blue seas [digital] p12 40 amp The""" most adjustable by far"" but it appears the most expensive adjustable amps x1amp and voltage adjustable x .05 increments float timer adjustable and amperage absorb trigger point adjustable for when it changes to float .[this allows for fridge loads etc ] Sterling procharge 20,30,40,50,60 $ around 630 for the 40 amp . The 50/60 amp are very expensive [amp adjustable %100, 75,50,25][has the ability custom voltage profile][lithium ] low pwr usage Projecta 50 amp does 50 and 25 amp but uses way to much power watts to do this for a 1kv gene $$ 550 Has seperate volt detection in the charge cable oz charge 30 amp adjustable for lower amps and low power usage 410 $$ Enerdrive pdf files appear a little incorrect contradict themselves 40 amp $515 Requires a call to Enerdrive 700watts on 40 amp Can any body add to this eg more selection ,and or ,cheaper prices [we all like that ] cheers swampy
