Good job! :)

Nice :rolleyes: How many kWh now?

Thx, Yes :) Temporary mounting

Updated to 7s60p -> 4 kWh I designed it to 60A max(1A per cell) Packs busbars are equal for every cell, I made it from 35mm^2 copper wire Next step is 60A BMS and main battery busbar (to connect other 7s packs i future)

more data @pdf

At 3s20p like on your picture you'll need over 1.2m of busbars. For 12V 45A at 12mm^2 copper (not taking into account crimping resistances and wirring cell-busbar!) You will lost 7.5W on heat

Hi, charge cells to 4.2V then check self discharging - give them few weeks and check voltage drop Exploited battery do not have 1% of capacity because they will have big self discharge or wasting charge current on heat Cell cycle life is depend from using currents, bottom and top voltage...

1. Look at data sheet -> check battery capacity at discharge current (mA or C) 2 Check Your discharge current Bigger discharge current = less battery capacity Temperature also is matters

thank You

You right,can somebody recommend something cheaper than batrium system?

Hey, sorry for late reply, now itssomething about 2,7 kWh For fusing I use Eaton DC breakers, ANL fuse on battery,SchneiderB10 at AC site ---- update :D added repacked 77pcs. INR18650-29E and 35LGDAS31865, now its 7S40P with ~2,7 kWh added some breakers, bus barand metal case...

ok, problem solved... I was try to conect with my new 1206AN and I have success probably somethings is wrong with my 1210AN controler I attached pdf from EP ever support with COM and ID settings, maybe be useful for somebody

If its still smelling probably its must be still on current, check Your packs for heater, how big is yours packs? or you broke some cells while you harvesting it?

Parcel arrived :D Another Tracer - 1206AN with temp. sensor Today start working with my 2x 10W in series, very old china panels :D I planing to buy another solar panels and set it: 1210AN with 1x 330W panel 1206AN with 2x 195W panels in parallel Meanwhile I finish capacity...

I try everything in settings options, also try on another PC - same issue (both win7) Now i waiting for second Tracer, if i'll have the same situation i'll try with other cable
