Thanks, Spot on and it looks a lot easier then trying to squeeze 3 wires into one. https://hobbyking.com/en_us/turnigy-180a-watt-meter-and-power-analyzer.html- How would I wire this to the bike as permanent fuel tank?

If I was to make up a 3pack parallel lead and was using xt60 connectors would I use 8 or 10awg?

My bad pasted the wrong link. Can't find the one I was looking at now so I'm going to stick with the 2 turnigy 250w chargers.

Sweet thanks, adding to the list now. What do you think of these chargers compared to the others as it doesn't mention anything about watts? https://www.stevewebb.co.uk/index.php?pid=CMLET0211&area=CHARGER. They are mains 240v and in the UK so not sure which ones to get now, as didn't realise the hk ones are from Hong Kong so more on postage and waiting time.

Thanks for all the advice gwhy. I am going to go for the 6s 8ah ×2 and just run one at a time for the first few weeks then parrelel them together at a later date. To start with I will buy some spade connectors and a xt60 connector for the battery side and will leave that attached So decided on 2× https://hobbyking.com/en_us/turnigy-graphene-8000mah-6s-15c-w-xt60.html 2× (1 as a spare) https://hobbyking.com/en_us/xt60-harness-for-2-packs-in-parallel-1pc-1.html 2× (for the cell checker so I don't have to keep unplugging them directly from the battery, to save on ware) http://www.kingslynnmodelshop.co.uk/p9299/Balance_Lead_Extension_300mm_6S_XH/product_info.html?utm_source=google&utm_medium=shopping&utm_campaign=xigen_shopping_feed&gclid=CjwKEAiArIDFBRCe_9DJi6Or0UcSJAAK1nFvdreu2Q6iZfj1bV-kvxloLn5_trPrFvGJwcTwQSzQChoCTx7w_wcB 2× https://hobbyking.com/en_us/hobbykingtm-cell-checker-with-low-voltage-alarm-2s-8s.html 2× (1 as a spare) https://hobbyking.com/en_us/jst-xh-parallel-balance-lead-6s-250mm-2xjst-xh.html For charging/balancing I'm going to get 2 so when I upgrad to 36v-48v I already have them, plus I can charge my 24v setup on 2 chargers quicker so win win. 2× https://hobbyking.com/en_us/turnigy-reaktor-250w-10a-1-6s-balance-charger.html And power with this http://www.kingslynnmodelshop.co.uk/Batteries_and_Chargers-Power_Supplies/c66_77/p4480/Pro-Peak_13.8v_Dual_Power_Supply_30A_415W/product_info.html And also a fuel tank meter https://hobbyking.com/en_us/turnigy-180a-watt-meter-and-power-analyzer.html ADDED extras for safety and future use https://hobbyking.com/en_us/nylon-xt60-connectors-male-female-5-pairs-genuine.html http://www.kingslynnmodelshop.co.uk/p12194/Ripmax_10AWG_Silicone_Wire_-_1M_Red_&_1M_Black/product_info.html http://www.kingslynnmodelshop.co.uk/Accessories-Wire/Wrap_and_Heatshrink/c21_341/p3399/Heat_Shrink_1M_Red/1M_Black_-_6.0mm-_on_order/product_info.html 2× https://hobbyking.com/en_us/fire-retardant-lipo-battery-bag-220x155x115mm-with-handle.html All in all £236.91 from HK and £75 from king's Lynn model shop Grand total with P+P is just under £315 Thanks Dale.

Just found this https://hobbyking.com/en_us/turnigy-reaktor-30a-1000w-balance-charger.html But not sure on the best PSU for it, any help would be much appreciated. Thanks

Is this not a bit excessive 64ah lol So with this setup with a 20a charger and PSU would that charge and balance the hole pack in 30-60 mins at 64ah ??? Not going to bother with the BMS, I want to do all the work myself. Going to make up some male spades to xt60 for the main wires on the bike, also wire the voltage meter on the main loom so only powers up when the battery pack is fitted. I will be using 2×6s 8ah to start with https://hobbyking.com/en_us/turnigy-graphene-8000mah-6s-15c-w-xt60.html Then putting them in parallel with one of these https://hobbyking.com/en_us/xt60-harness-for-2-packs-in-parallel-1pc-1.html I will buy some extender cables for the balance ports so I can plug the cell checker in via this and that will allow me to plug and unplug as many times as I like without the risk of damaging the port on the battery side. Job done. Just can't decide on what charger and PSU, as I would like to charge it in under an hour if poss Job done.

So with this I would charge the hole 6s 2p on one charger. Sweet just need a charger that can do the hole pack in 1hr, could you advise on the best that's not stupidly expensive. I've got £300 for the project as was going to buy a boost bikes setup but decided I could build so much more for the same money. So looking like £150 for bats and everything else so leaves the same for charger and PSU unless I get a 240v setup as will only be charging at home.

Just found these https://hobbyking.com/en_us/turnigy-graphene-8000mah-6s-15c-w-xt60.html Looks like a good pack and would only have to parallel 2 together for the desired 22.2v at 16ah and only £50 each so could even buy 3 and have a 24ah pack. They are a bit heavier than I was thinking of using but look good, have the xt60 connectors (want an easy click together the first time then when I get the 16" I'll make all my own connectors) and say they are in the UK. Would still buy the 2 chargers I mentioned earlier and the PSU unless anyone can advise on anything different. I take it at 15c for the little 24v will be fine? Sure someone said it's 40a con and 50a burst As said earlier on I think I've got it, so really I'm just looking for confirmation.

So does anyone know someone who has one? Or uses one in computation? Decided on the oset 12.5r as just can't find enough info to warrant buying a torrot at the moment, but my oldest will grow out of it quite quick so maybe a T12 will be next.

If I P4 3s batterys together will the charger read that as a 3cell pack or a 12cell pack ?

Thanks for that, do I need a BMS for lipo's? I thought they were only needed for building li ion. Wasn't going to bother with BMS, just build a lipo pack that I will monitor myself. I don't trust it will be working as no indication of anything till the pack is knackered. So with the lipo in mind, will the 2 chargers I mentioned earlier be OK for the job with that PSU I also mentioned? I will run a fuel tank on the bike and do all the monitoring once the day if over, will also get a cell checker so I will be the battery monitoring system. Sorry if I have misunderstood anything.

So it would be a safe configuration as long as I didn't plug anything in the wrong way ? I did see that big battery but was thinking about what someone said earlier (possible you) about if a cell go's bad then would have to scrap the hole thing, plus it's not stocked in the UK by the looks of the hk website. I was thinking about either 2x6s 8ah or 4x3s 8ah or 8x3s 4ah, all giving me 22.2v 16ah. Going to work out what is best for weight, availability and price to decide but I get what your saying about less connectors. I would mark and label everything and be extra careful when charging everything and putting it back together. I'm looking at 2x https://hobbyking.com/en_us/turnigy-reaktor-250w-10a-1-6s-balance-charger.html And Will add a voltage meter for on the bike to keep an eye on overall and check cell levels before charging. And was thinking of powering the 2 charger with something like http://www.kingslynnmodelshop.co.uk/Batteries_and_Chargers-Power_Supplies/c66_77/p4480/Pro-Peak_13.8v_Dual_Power_Supply_30A_415W/product_info.html Would this be man enough to power the both with a max 415w if the chargers are 250w each?

Dimensions of the bike are a big part of my battery choice as want it built and ready to go the day I get the bike. So with the 8 x 3s lipo I was taking about, am i right in saying this is the correct way to put them together So if I P1+2 and P3+4 using theses https://hobbyking.com/en_us/xt60-harness-for-2-packs-in-parallel-1pc.html This would give me 1+2=A and 2+3=B. Could I just plug A+B into this https://hobbyking.com/en_us/xt60-harness-for-2-packs-in-parallel-1pc-1.html and that would give me one single pack (say 4 x 5000mah = 20ah), would this would be the correct and safest procedure of building it? Assuming this is right and I have done this twice over (so now have 2 x 20ah 11.1v) is it just a case of plugging both of these Into this https://hobbyking.com/en_us/xt60-harness-for-2-packs-in-series-1pc.html and that is the correct and safest way to contact these in S to get the desired 22.2v 20ah. I understand I will have to change the connectors on the bike and maybe some others as well but just want to make sure if have understood it all before I send the money, think I got it sorted just not 100℅ if it can be configured in that way. Building my shopping list at the moment so any advice is welcome.
