  1. don't buy a prebuilt lithium battery , build your own ! figure out what voltage you are gonna run and go from there . there is plenty of cells out there to choose from ( Headway 38120HP , Planno lLTO , Ying Long , Shengquan LTO, Honda EH5 , CMAX ,etc..) go to Facebook groups to research ,learn , ask questions , find out where to get legit cells to buy and if you feel you still question whether you can or can not build your own bank ., there are quite a few legit people to build you a premade bank out of legit cells that you will be more than happy . by the way , you will then find out how cheaply those limitless and D4Sound premade banks are made ...
  2. rhose batteries are really not for car audio but for rv's, trolling motors, etc. says 80 amps max charge , you would of been way better off building a bank of Headway 38120 hp's
  3. when assembling cells with your busbars , use some eva or other non-conductive material to put between bars/plates so you don't short your cells . make sure you balance your cells by connecting all the positives together and connect all the negatives together (DO NOT CONNECT POSITIVE AND NEGATIVE )and let them sit to balance themselves out . put them somewhere safe where they won't be shorted somehow
  4. the bank catching fire in your vehicle is not much of an issue as long as you don't dead short it ! i was primarily talking about when you build it , use caution as to not short the busbars , the arc will melt metal like a plasma cutter !
  5. just take your time and BE CAREFUL !!!
  6. wonder what's up with the 14.8v set point then ???? well then it sounds as if you'll be good to go
  7. by the way , if anyone is interested this guy in the video makes very good amp repair videos and is VERY knowledgable and explain things very well
  8. hopefully , if not , run your Headways at 14.8 , but buy new cells from BatteryHookup. https://batteryhookup.com/products/new-headway-38120-hp-3-2v-8ah-lifepo4-10-20-2020
  9. Lifepo4 is Lifepo4 , should not be charged above 14.6 whether it's a JYPower battery or a Headway bank , period . as with anything , always research things for your own knowledge . i myself , with what i've learned would never buy a pre-made battery bank from jy power, limitless, d4s, underground power, etc.. build a better bank out of Headways or LTO cells that will give you way more power reserve and output for a lot less money...
  10. Mechman makes a 240amp for your vehicle and i'm sure other alt companies can accommadate you . i have Crossfire XS-M 6.5'sin factory door location and XS -ST1 super tweeters (in A pillars) , will probably end up adding another pair of the 6.5's in the doors . been slowly getting it done !
  11. i've got two Crossfire C7v3 15's d1 pushed by a Deaf Bonce AAK4000.1 . ( have the subs and amp already but not installed , building the box right now waiting on a 5' x 5' of 3/4 baltic birch for baffle (subs up /port up ) this is going in my two door blazer in my avatar, going to install 190mil vibraflex for the roof with some GP STFU 200mil on top of that! then get everything installed one of these days !!! with 14.8 voltage , you are gonna shorten the life of the cells , people will tell you they run fine on that voltage but wonder why their bank degrades after awhile , i am buying new cells from BatteryHookup , so i'm gonna do it right!
  12. talk with your alt builder , pretty sure they can bring the voltage down to 14.4-14.6 , if not go with a Mechman
  13. i hear you about weight ! my 7cu.ft. box 1in. baltic birch with 3/4 added to baffle and two 55lb. subs and i'm hating the full weight of it !
  14. with LTO (Ying Long , lishen, Planno, etc..)unless your running dual alts (stock alt for vehicle and higher charging alt for LTO bank ) you are then wanting to charge about 15.5 volts . the thing with Lifepo4 (Headway) you can use your stock voltage alt , not all vehicles can be run on 15+ volts , hence why i choose Lifepo4 . my blazer's charging is around 14.2-14.3 on a 240 amp Mechman , was gonna get a 400amp alt but i really don't need it , maybe if i get another AAK4000 !
  15. just be careful and DO NOT OVERCHARGE the bank of Headways beyond 14.6 volts!!! i would also not advise using an alt with a 14.8 volt set like a CES , you're better off with a high output alt with factory voltage set (Mechman or others that don't have a higher than stock voltage )unless the alt manufacture can set voltage to 14.6 , cause 14.8 charging will degrade your cells over time .
  16. was reading through the sticky on this board and wondered about it till i saw this video on youtube , so yeah , gonna skip the relay !!!
  17. a BMS is not advised as it will limit current , you need an active balancer like a Heltech . BMS's are for solar storage and such as when you don't need high current discharge .
  18. absolutely.. i really doubt you'd pull over 400 amps from that Taramps and don't know how many amps you pulling from the 4ch. but , depending on your busbars, you should be able to pull 750 amps from that bank.
  19. unless you're buying used cells , Headway 38120HP cells cost around $14 each x 32 = $448 , some busbars cost around $180-$200, plus misc. bolts , lugs ,cable, plus a $20-$25 balancer . you are actually over $600. plus then there is cost of an enclosure for the bank . most of the times people have stuff laying around that they could use (extra couple feet of OFC wire, cable lugs , ring terminals , heat shrink , etc..) but if you don't , these things add up . if you were to make some busbars out of aluminum , you looking at 25-30 bucks instead of $200 for pre-made bars . also an extra cost ,if you don't have one is a power source to charge Lifepo4 batteries. so if you can get costs down around $400 , you are buying used cells and fabbing up some busbars . for most though , look to spend at least $600. by the way, ditch the isolator and let the Headway's run your whole vehicle , you'll get better voltage..
  20. by the way , DO NOT USE THIN BUSBAR PLATES like Parker on youtube , get some Coventry or Project DB bars , i got some off Ebay that are 4mm thick ( the plates in the picture i posted) the ones on Parkers you tube video are 1.143 mm thick , yeah not enough pulling 400-600 amp through it ! i'll be pulling about 450 max amps (Deaf Bonce AAK4000 & D'amore 400.4 ) using the plates(busbar) i got allows me to mount in a group 31 battery box
