Hello everyone,
I'm planning to build an autonomous transportable speaker with the help of JAB boards to amplify and power my system. I plan to use the JAB3-1100 board (1x100W) for my two woofers and the JAB2-30 board (2x30W) for my two tweeters. I would want to use the JA-11113 battery boards to power my system but I'm not sure if I can connect several of these to increase capacity.
I contacted Sure Electronics and they answered me it was possible to connect several JA-11113 battery boards in parallel, like it is said also in the datasheet, but on the product page on Wondom website they say it is forbidden to connect them in parallel. So I'm very confused now, has anyone ever used these battery boards in parallel ?
All the best,
Ewen

I have already found two websites forbidding the use of Ja11113 battery board being used in parallel OR series .
You provide the lithium batteries -- what if one of the parallel connected boards batteries went down /needed recharging before another one ?
It says its = BALANCE and protection --so if one was out of balance due to low batteries what would the other protection circuits on the other boards see ??---- a big fault.
Its in RED on the websites with a big disclaimer if you try to do that !
I wouldn't ignore that advice .

I suspect you could just wire a plain battery holder in parallel with the one on the board, so that instead of a 3S arrangement you have 3S2P. Or, buy a 3S PCM or BMS board and a number of battery holders. The PCM (protection circuit module) provides the overcharge, overdischarge, and overcurrent protection; not all include balancing, but there are add-on balance boards if necessary. Look for 3S BMS or 3S PCM on eBay or wherever.
