    HobbyKing ECO6 chargers - WTF!

    I had two eco6's and they both died pretty quickly, I switched over to the accucell-8 and it runs much cooler and seems to be a better unit, I have had no problems so far, so its a good alternative for not much more cost.

    Combine volt amp and Ah meter for USD $15

    it says 20-70C, but looking at the analogue display it goes a bit higher... I purchased a cheap temp meter before that had 70 as the upper limit before, (not the same one) but I took it up to 90 without anything happening... maybe past that point it would damage a component and make the readings...

    DID I SCREW UP??????

    Yeah the difference is you have two 10s 2p blocks instead of five 2s4p blocks The convention is to Parallel first, then series, as this allows the parallel packs to remain in balance with less wiring... If you go series first, simply make two 10s2p packs (your series block in your original...

    DID I SCREW UP??????

    Hi, Keeping in mind that each of your lipo packs is 2s2p, then looking at your diagram, you have one 10s2p pack (your series block) and one 2s10p pack (your parallel block) each of the cells is 3.7v nominal 3000mah. so your series block is 37v 6Ah and your parallel pack is 7.4v 30Ah...

    600W 10-60V to 12-80V converter

    The 3Kw supply is 50.4v output, and feeds into the DC-DC which I set to 66.4v to charge my 16s Konion pack. Haven't measured current yet as I popped my 60v Wattmeter on it...

    600W 10-60V to 12-80V converter

    Haven't needed to yet - need to get my electric motorcycle running first before trying to up power. The main issue would be to ensure they output at exactly the same voltage so that load is evenly distributed... I had some information somewhere on load sharing, but I lost it a while back...

    Combine volt amp and Ah meter for USD $15

    I purchased the original meter in the thread because of its expandability, planning to use an external shunt. After some communication with the seller who kept asking me to wait two days and then offered to pay to have it looked at by an electrician or something here, they gave me a full refund...

    Combine volt amp and Ah meter for USD $15

    Hello all, I purchased the original meter in this thread, and am now trying to get it to work with an external 200A shunt purchased from the same seller... Currently eyeing out JMP1 and trying to work out where to insert the voltage reading across the shunt into the circuit. The four unused...

    the item just got added to one of the sites I frequent: http://www.goodluckbuy.com/dc-dc-600w-10-60v-to-12-80v-boost-converter-step-up-module-power-supply.html if only it was there before I went through the hassle of taobao!

    600W 10-60V to 12-80V converter

    I'm still trudging through my taobao order, my total final price for 3 is $66. The savings from ordering through taobao will increase significantly with a purchase of a higher number of units, even for 5 the savings would be much greater. I'm hoping they work better with 48v input, common sense...

    ahaha 100? pretty high. Did he mention what kind of discount it would be? Definitely cheaper through Taobao at those quantities. much much cheaper!

    different HP server power supply modding

    connected B11 to ground. B11 showed a small voltage before grounded which is a good sign! :D now to find the other pins!

    600W 10-60V to 12-80V converter

    The maximum voltage rating of the input caps is normally a good indicator of the upper limit. I lost the guide for paralleling power supplies, am looking for it again.

    Just on one side - the pinout seems to be right, so to get it on I do A11 to GND? anything else? Thanks!

    Greentime controllers

    Just to post my experiences with the controller: I purchased from Leo a couple of months ago, good communication, he promised to send matching connectors with the controller which didn't eventuate. My order took AGES to send, Leo kept making excuses and I had to extend the processing time...

    This is the precise one I purchased: http://www.ebay.com.au/itm/190680669114?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_1446wt_961 thanks for the pinout Stevesie, but I am only able to find pins A1, A5, A10, A15, A20, A25, A30, A32. Unless, do the pins mean the little holes in the...

    different HP server power supply modding

    Mine is slightly different, so frustrating, must have tried a hundred combinations right now, it's hard with only two hands :lol: Thanks for finding one with a similar design though, it will help! I ended up just buying a 3kw 48v 57a power supply that has already been reverse-engineered, but...

    600W 10-60V to 12-80V converter

    I have a link bookmarked at home which shows how to ensure the load is equally shared by using load resistors. I'll edit this post to include the link when I get home.

    600W 10-60V to 12-80V converter

    A supply doesn't need to be isolated for running in parallel, only for running in series. Someone correct me but I am 99% sure, and sure enough to hook it up that way without doubting myself. Yeah the 3kw supply is 48v 57A or something, costs <$50 on ebay if you want to find one. Although I...

    600W 10-60V to 12-80V converter

    Yeah it's pretty similar. But also, I just bought a 48v 3kw server supply! So these can be used at full 600 Watts! the supply cost 50 dollars, so 1.8kw of charging power isn't bad for 120 dollars!
