Dear Davide, I leave you in Vivian's hands, I'm sure you will come to an agreement., Vivian is professional in our product.

—— Davide Bet

Here is the signed PI. Thank you , We hope

—— Mr Ander

12V 110Ah battery pack for solar product I like your solar battery pack. Good quality and delivery fast.

—— Eyal Dolev

The battery pack is more atractive for us . May I receive drawing of other pack 12V 20AH with dimentional info ? I need 50pcs to test .

—— Nizamettin

We have received the battery packs and performing tests have passed . We are impressed by the assembly. it is almost the best one . thank you

—— Alexander Kozhushko

Pictures show a nice battery pack, performance is ok , We need serial connected 4cells (4S1P) configuration with protection circuitry

—— George Komisar

big thanks for your work, we got the cargos last week, it seems nice.

—— Johnny Black

I think it is a good idea to solve the problem, I am really appreciate you would like to help us.

—— Simone Kowalk

yes , we received the batteries and chargers last Friday, Everything looks great,well packed, no damage and dlivered in the time frame as promised.

—— Met vriendelijke groet

Thanks for your input, we have checked each and every think and on our side every thing is great. Just proceed to submit the company documents to get approval.

Parallel or Series?In general, when selecting a power supply, it is important to choose one with appropriate voltage and current rating to support the system requirements. Typically, power supplies are connected in parallel to increase the power/current rating and also to increase the system reliability by providing redundancy function. Series connection of power supplies can cater to special needs of the system when requiring higher output voltages.
1. Parallel OperationThe purpose of parallel operation is to get increased output current. When in 1+1 connection, the total output current will be maximum 2x of each individual power supply rating. Load sharing between the 2 supplies can also be achieved. (See “Load Sharing” topic below). When connecting more than one power supply (N+1), it is recommended to connect using external ORing diodes (Delta recommends the use of DRR-20N or DRR-40N). See Figure latest company news about How to Operate Parallel and Series Connection  02.To achieve redundancy function, the system current demand should not be greater than the rating of a single power supply. More details are available under the “Redundancy” topic later in this article. In the case of redundant connection, system operation is not disrupted when there is a failure in one of the power supply. This prevents overall system downtime.Load Sharing Concept
The power supplies can be connected together for parallel operation to increase the output current. See Figure 1 below. To achieve this, it is important that the output voltages of both power supplies must be within 25mV difference of each other. The output voltage adjustment must be done at 50% of max load current or at a load current 25% and above ensuring that both the power supplies have been adjusted at the same current level independently.http://www.tacbattery.com/
