    Aaaaw always nice to get some good feedback - thanks for taking the time and I hope it keeps on delivering!

    Yes I sell them for R900 at the moment - free shipping included. You are welcome to PM me for details.

    Hey JJ, I'm using a 5A continuous discharge off the shelf PCM. As mentioned on page 2 of this thread normally these batteries are "dumb" when doing 4 or less cells. BMSs with DOC settings are not worth the money and space they take up for this application (my opinion) and will take a hammering with dust and vibration. The PCM limits the voltage levels and cuts out - simple as that. Hope that answers your question?

    I completed the first 4 cell 10 000mAh bike light battery in the country (that I am aware of) and will be testing it over the weekend. This battery uses the (relatively) new 2170 size cells rather than the 1865 cells that I have been using in the past. The 2170's are used in the current line of Teslas but will soon be replaced by the 4680 which I'm also eager getting my hands on. Pics below shows the size difference between the 6800mAh 1865 pack (black) vs 10 000mAh the 2170 pack (blue) - I'll call it "The Mega". If tested successfully - it will be ideal for the Munga/Freedom challenge riders.

    Can't agree with you more. Personally I am a big fan of Ryder's Concept 1000 seeing as I can pop cells in and out at will and/or carry a spare. This coincides with the movement towards clean and uncluttered handlebars without spinning the lead cable 50 x around it. I do however believe that battery packs have their place in ultra races (I sell majority of my packs to Freedom challenge and Munga riders) for the time being at least. Thanks for your advice - it's exactly the type of input I'm looking for.

    Hi all, I'm currently in the development phase of a new battery pack (4 cell 10 000mAh - 1st of it's kind in SA) but would like to gauge the market to determine whether I keep it for personal use only or market it as part of my existing range. All input is appreciated and welcome ????

    This is a very accurate post and probably the most cost effective solution. Just note that the term "deep cycle batteries" can be deceiving. Your depth of cycle severely impacts your battery's lifetime, my rule of thumb for sizing Deep Cycle batteries for systems are double capacity so that discharge never exceeds 50%. I believe that is what Karman has done as per quote (i.e. one battery will do the job but two batteries will protect the discharge). While deep cycle is cost effective most professional installers will opt for a lithium solution today seeing as they have 10 years' warrantee on the units which they need to cover. Lithium can also be specced at full capacity for discharge with no threat of damage to the battery (where a BMS or PCM is installed).

    Achieved a very respectable 6.5 hours runtime on the 2100Lm setting.

    So here's another update: A client requested a 6 cell 7.4V 10200mAh battery and today is test day. Once again looking forward to results compared to similar units going for 2 x the price. I'll post final times once the lights go out ????

    I can supply this unit for R1400. There's a catch though - the 3 blue circled ports are all the same (like that of a battery pack) thus your ONT and Router plug must look like the red circled plug (like that of the bike LED light) in order to make it work. The ones on Takealot (that I've seen) have 1 x 12V port, 1 x 9V port and 1 x 5.5V port. Mine has only 2 x 12V ports so you can check your gear's supply voltage and let me know if this will suit you.

    PM Sent. Our standard chargers are R250 (including shipping) but this one will have some mods due to your unique Molex connector requirement.

    I have had a lot of interest in these battery packs since posting my research and experiments on this thread. I am happy to report that my initial feeling wrt pricing of these battery units were correct as I believed it can be done much cheaper. I have started selling these units for R850 (incl shipping) which is the 4 cell 6800mAh 7.4V unit. It is compatible with Extreme Lights, Pyrolights, Magicshine, Magiclight, Gemini and Fluxient LED lights. I also sell chargers for the 3.7V & 7.4V battery packs.

    Got some time to test the the 2100 lumen setting on the Extreme Lights with my Alpha Battery pack. Total runtime in this mode was: 4 Hours 18 Minutes 03 Seconds ​I was a bit disappointed seeing as I was hoping for a 4h30m + Because I needed to drain the pack fully to test the recharge time as per Hairy's request I continued to let the light run (it switches over from 2100 lumen to 200 lumen on its own as soon as the indicator light starts flashing red) but to my surprise the light continued in this mode for a further 7 hours and 34 minutes. The setup with the fan is shown below. Second picture shows the automatic switch-over from 2100 lumen to 200 lumen in the GoPro sequence. Next test will be the 750 lumens setting...

    Full charge time for the pack from drained to full was 7h46min - you were more or less spot on
  15. Lamber
    Thanks for that - definitely worth testing as well! My charger is rated at 1A @ 8.4V. Seeing as this is a 6.8Ah battery I would assume around 7 hours. The 1.8A chargers which are readily available should halve that. I will test this over the weekend as well so that I can include it in the factual results next week.
